Whats the problem with my truck? 1998 Toyota Tacoma

ANSWER : It is very likely that you have a powertrain control module failure. This can happen often on many GM vehicles. I would recommend having the powertrain control module tested and replaced as necessary in order to resolve this issue. After the powertrain control module is replaced, a reflash procedure will be required so that the vehicle can relearn all of its primary engine data. Once the reflash is completed, your vehicle should no longer have this issue.

ANSWER : The torque converter clutch is not releasing as the transmission is shifting. Try pulling the fuse to the torque converter labeled as TCC and see if the symptoms change. If the vehicle stops acting up, then the torque converter clutch solenoid is active and not releasing. If the symptoms are the same, then the torque converter clutch is melted and needs replaced (torque converter replacement). If you need further assistance with your transmission shifting hash and stalling, then seek out a professional, such as one from Your Mechanic, to help you.

ANSWER : Hello – you may have an overheated engine, with a blown cylinder head gasket (or other overheating damage) or simply a run-down battery. The same serpentine belt that drives the alternator also drives the water pump. Depending on how long you drove after the belt failed, the engine may have overheated – with some damage. I recommend an 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 : The problem sounds like you have flat spots on the tires in the rear when the tow truck operator dragged and pushed the truck with the transmission locked. I would recommend having a vehicle safety inspection to see if there is tire damage or other possible damage done by the tow truck. Have a mechanic from YourMechanic come and do the inspection and check the problems for you.

ANSWER : Hello – when the AC compressor fails, it can deposit a fairly large amount of metallic debris throughout the AC piping and components. It is VERY difficult, even with chemical flushes, and added filters, to get all the grit out of the system. The result is that the new compressor has to deal with metallic debris, which can quickly trash a new compressor – spreading more junk into the system. Replacing the dryer, metering orifice, or evaporator control valve, and thoroughly flushing the system with appropriate fluids meticulously is the only solution. I recommend an AC compressor replacement by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, and carefully rebuild your AC system.

ANSWER : The problem is in the horn pad. The horn pad may be damaged or changes in temperature can cause the contacts to touch in the horn pad causing the horn to beep. you may need to call the company to come and fix it or remove the horn fuse until it is fixed.

ANSWER : Hi there. Assuming that both engines are the same size, the compatibility of "fitting" should be OK. However, since this is a service we don’t offer, we’re not best suited to provide the best advice on this. I can tell you that a common problem have with replacing motors is communication with the ECU. In most cases, it will require reprogramming by a specialist in order for all the systems to work correctly.

ANSWER : The first thing to do is disconnect the A/C compressor and then turn on the A/C and see if the engine still stalls. If it still stalls, then you have a problem with idle control circuit and would need further diagnosis. If the engine idle goes up, then connect the A/C compressor so it kicks in and see if it kills the motor, then you may have a compressor locking up and stalling the motor. The A/C pressures will need to be checked and monitored to see if the high pressure goes too high indicating an A/C problem that will need a mechanic to diagnose in person to see what is causing the A/C pressures to be so high. If you need help with this, have a professional, such as one from YourMechanic, inspect your truck’s stalling issue and let you know what needs repair.
