Throttle body replaced under warranty has a defect, now out of warranty.

ANSWER : Hi there:

Although we’re not lawyers and not permitted to provide legal advice, to my knowledge, State of California "lemon laws" apply to new vehicle purchases as opposed to replacement services; however, you might want to contact the California Bureau of Automotive Repair for specific guidelines. What I’d advise is to not continue taking your vehicle to a dealership if they are not going to cover the components under warranty. Instead have a professional mobile mechanic complete these repairs; or sell the Suzuki and purchase something a little more reliable; as fuel system issues are common with these vehicles.

ANSWER : The engine running rough for a moment after using throttle body cleaner is a normal symptom. This should only last for a short period of time and then go away. If the issue does not go away after a few start ups or a short drive, it is possible that the throttle position sensor or mass air flow sensor could have been damaged as a result of using the throttle body cleaner. Many throttle body cleaners will specify if they are sensor safe. IF the throttle body cleaner is not sensor safe, one of the sensors may be fouled out. I would recommend having a drivability inspection performed on your vehicle to determine the exact cause if this issue persists. Consider YourMechanic, as a certified technician can come to your home or office to determine the cause of this issue.

ANSWER : After you replace the throttle body then all you have to do is turn ignition on with all accessories off. After 29 seconds of not touching anything the engine computer will relearn the new throttle body. Leave it on for at least 2 minutes before turning off. Start the vehicle and see if vehicle idles good and throttle works before driving. If no Check Engine Light comes on then you are good to go.

If you run into any problems or decide to get some help with the job, consider YourMechanic, as a certified technician can help ensure the correct installment of your new throttle body.

ANSWER : Hi there. This video is actually pretty good on learning how to correctly replace the throttle body on your vehicle. This is another good video to learn from. It is possible that your fuel injectors are still clogged with debris or you have a vacuum leak that is causing this problem. Double check all of your connections first, then I would start looking at the EGR valve, mass air flow sensors and other fuel system components, as that is typically the cause of these symptoms.

ANSWER : Hello,
I believe what you are describing is a problem with your PCV valve. A bit of oil in the throttle body is not going to harm your motor and is certainly not going to cause it to blow up. At an idle, the PCV valve restricts air flow, to reduce this problem. At high manifold vacuum (idle), a spring loaded valve is drawn up and partially restricts flow to the crankcase. The PCV system is relatively simple. An inlet hose connects to a filtered air source. This is used to supply clean air that is drawn through the engine. Most of the time this air is supplied through the engine air filter. On a few designs there is a separate inlet filter that cleans the incoming air for the PCV system only. This filtered air flows through the engine, picking up fumes and vapors. The air exits through another hose, connected to manifold vacuum. The flow of air draws fumes from the crankcase and burns them harmlessly in the engine. This also creates a slight vacuum, relieving any pressure that may build. Negative pressure helps to prevent oil leaks and oil consumption by the engine. The PCV valve also helps regulate the amount of air flow, which helps prevent oil being drawn out of the engine. When the PCV valve is not working correctly, this will cause an imbalance in air flow and vacuum causing the check engine light to come on. i would suggest having a professional from YourMechanic come to your location to take a look at your Jeep.

ANSWER : When it comes to remanufactured or brand new you are better off in most cases with the new one. The reason the company did not have the remanufactured one in stock is due to there has not been enough old cores returned to get rebuilt yet or the remanufactured part is in short supply. When it comes to getting a new or remanufactured part I have seen mixed results. The remanufactured one rebuilds an old throttle body using the base housing and installing all new parts in to it. The replacement parts will have to meet or exceed the manufacturers part performance and specifications. Just remember that if the manufacturer identified a product problem and changed the unit specification the dealer will get the new designed part before the aftermarket companies will and you may get old stock on the aftermarket where a dealer will only sell the newer part. If it was myself I would only use a factory new throttle body on this car. It may cost more but at least I would know I would get a new quality part with any last minute changes to product.

ANSWER : Hello – the first task is to check for problem codes, whether the Check Engine light is on or not. I suspect there are still wiring issues with the throttle body, and if so, there should be problem codes to guide you. I recommend a engine inspection performed by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, give you an accurate assessment of damage and cost estimate for repairs.

ANSWER : It is always recommended to replace the sealing O ring or gasket under a throttle body when removing or replacing it. If not then a vacuum leak can develop causing driveability symptoms and check engine light to come on.
