RPMs increase at traffic light with foot on clutch
This has happened two different times: when I was at a traffic light, the RPMs increased. I don’t have any warning lights on my dashboard either before or after this happens. My car won’t move forward when this happens since my foot is on the clutch. I went to the dealership, but they couldn’t duplicate this. Can you tell me what is causing this to happen? Thanks.

Hi there. We will be happy to help with your 2005 Honda S2000. The surging you are experiencing is very likely a result from a stuck rotary air valve inside of the idle air control valve. This is a common problem that many S2000 owners have encountered. Cleaning out the idle air control valve should bring the driving condition back to normal. If you want to have this looked at by an expert, a certified technician from YourMechanic can come to your home or office to diagnose your RPM issue.

When does VTEC engage? VTEC requires oil pressure and ECU logic to engage and seems to engage anywhere from 5700-6200 rpm on all S2000.
Honda S2000 – 9,000rpm.
The S2000 was introduced in 1999 for the 2000 model year and was given the chassis designation of “AP1”. It features a front-mid engine rear-wheel-drive layout with power delivered by a 1,997 cc (122 cu in) inline four-cylinder DOHC VTEC engine.
The high-revving engine pushes the sports car to 163 mph.
Enthusiasts have been asking Honda to bring back the S2000 for years, but to no avail.
At 3000-5400 RPM, depending on load, one of the VTEC solenoids engages, which causes the second valve to lock onto the first valve`s camshaft lobe.
At low RPM, the engines are docile and quiet, but when the VTEC system crosses to its higher RPM cam – that is, when “VTEC kicks in,” as the high-lift switchover has become known – the engine note takes on a sharper edge, with an increase in power that`s immediately noticeable from behind the wheel.
The normal RPM range for cars on highways is generally between 1500 rpm and 2000 rpm. The idle rotation ranges between 600 rpm and 1000 rpm. A diesel engine usually stays idle at around 750 rpm, while it runs at a speed of 110 km/h on 6th gear at 2000 rpm. However, petrol engines rotate at 6000 rpm at high speeds.
Shifting between 2000 and 3000 is normal.
Fewer than 700 S2000 CRs were produced between the 2008 and 2009 model years. To reduce weight and lower the center of gravity, the S2000 CR did without the base car`s spare tire and only offered air conditioning and radio as options. This CR has those options, making it less rare but more livable.
The S2000 was based around an extremely rigid steel chassis that Honda dubbed the X-bone frame. Claimed to be lighter and stronger than nearly every contemporary sports car, the X-bone had a 2400mm wheelbase and offered perfect 50:50 weight distribution as a result of the engine`s position behind the front axle.
We`d lean toward well-maintained second-gen models with their improved low-end torque and refined suspension, though there`s undeniable joy in revving an early S2000 to its 8900-rpm redline. Of the early cars, the 2002–03 examples are the best, with their transmission and interior upgrades and a glass rear window.
Prices for a used Honda S2000 currently range from $16,999 to $69,990, with vehicle mileage ranging from 9,324 to 147,281. Find used Honda S2000 inventory at a TrueCar Certified Dealership near you by entering your zip code and seeing the best matches in your area.
VTEC, however, tends to perform between 4000 and 5500 RPM, based on the engine`s condition, oil pressure, and other factors. Every rider finds the sensation of increased performance with high efficiency to be particularly thrilling. So we closely check for the moment when the VTEC kicks in.
At approximately 6,000 rpm, a solenoid opened a valve, sending oil pressure to pins inside the rockers. These pins locked the two outer rockers to a third, center rocker, which engaged a more aggressive center cam lobe, and that lobe supplied the additional valve lift and duration needed for high-rpm power.

When replacing my fan clutch should I change my cooling fan to a flex-a-light and get a new flex-a-light clutch?
ANSWER : Hi there. It is best to always put on the OEM parts that are required for the vehicle. However, you can get a flex-a-light clutch fan for your vehicle as long as it will bolt up to your water pump pulley and clear the radiator and shroud. I recommend having a clutch design fan for your vehicle and not a fan that spins with the engine all the time. Those fans will cause the engine to overheat on highways and in town especially in hot weather. If you need further assistance with your cooling fan, then seek out a professional, such as one from Your Mechanic, to help you.

Abs light, emergency brake light, steering wheel assist light, engine light, EPC light, traction control light
ANSWER : Hello, thank you for writing in. The vehicle does utilize a lot of the same sensors for these systems. Are there any other codes that are coming up when this code appears? If so you will want to take these into consideration when processing the repair and making a diagnosis. The module may be bad, and replacing it should fix the problem. The lights should turn off once the main computer recognizes the new module and the sensors sync up. If you believe the sensors need to be cleaned you may do so. Do as minimal as possible to make sure you are not damaging the sensor or disrupting the wiring inside. A bad connection would make the lights stay on. With so many lights that are effected by the module being illuminated, the module is likely bad or does not have a connection. Check the connection first and then resort to replacing the unit. For more help with these electrical tests, contact our service department.

No dash lights, back right tail light is out, no parking lights. Brake lights work though as does head lights.
ANSWER : Hi there. In many cases, when you have electrical problems like you’re describing, it’s caused by multiple electrical component failure. It’s likely that a few electrical relays are not working; especially if you have systems that utilize the same components (such as your brake light and tail lights). I would recommend having a professional mobile mechanic come to your location to complete an electrical problems inspection first, so they can pinpoint what is damaged and recommend the right repairs.

Battery light goes on when I start car then turns off, if I rev engine light comes back until rpms go down. Abs goes comes on/off
ANSWER : Batteries can die due to faults in the charging system so ideally a suspected "faulty" battery should be load tested before a decision is made to condemn it. The only exception to this rule is if the battery is already clearly "old" (greater than 5 years) but even then once you put a new battery in, as a replacement for a "dead" battery, you have to comprehensively check out the charging system. Diagnostic Trouble Code P0460 will result in disruption of the dashboard fuel gauge’s ability to accurately report your tank’s fuel levels. The fuel gauge readings may be erratic, or read somewhere off scale. Vehicles equipped with a low fuel warning light feature may also suffer from erratic low fuel warnings in the event of a code P0460. Unless the P0460 code has been reported alongside other trouble code, all of the vehicle’s essential systems should otherwise function normally. I would recommend that you request a check engine light diagnostic to first resolve the fault causing the P0460 code to set. The check gas cap light warning light could be due a faulty gas cap and/or small leaks in the EVAP system.

2012 equinox reduced power light engine light and traction light came on. Lost a lot of power got home and all light except engine
ANSWER : Your car has what is called a "safe mode" that will be engaged by the computer when it detects that something critical has gone wrong related to any of the major components in your engine chassis or power train. This may be related to a number of things, most of which should have been registered in the computer when the check engine light came on. I recommend having an expert from YourMechanic come to your location to inspect your check engine light and diagnose any codes registered by your vehicle’s computer.

When I put my foot on the brake my back left brake light goes off, when I take it off the brake the brake light comes on
ANSWER : I would suggest trying to disconnect and reconnect the wiring to the rear lights. I have seen these older Toyota vehicles rear lighting short out on the lights themselves due to the way the light circuit was made on the lamp housing. Look at the housing circuit on the light to see if one is touching another, and that could tell you why it is malfunctioning. There could also be a problem with the brake light switch. If you are not comfortable dealing with wires, I recommend getting in touch with a certified mechanic who can look at your brake light issue for you to see what’s going on.

First, the fuse 19 keeps blowing. When I hit the brake pedal my dash lights up. The third brake light acts like a running light.
ANSWER : Hi there. Check the wiring on the vehicle to the tail and brake lights. There is a cross short that is causing the lights to blow the fuses and make the tail lights brighter than normal. If you need further assistance with your electrical issues, then seek out a professional, such as one from Your Mechanic, to help you.
