    I was speeding in my nissan titan (112mph) and now my truck backfires and struggles to accelerate, jerks around between rpm’s and stalls all the time. Its only when I try to accelerate a small bit faster. My question is it the ect sensor? If not maybe the Tps sensor?

    I have a Chevy Impala 2000 and it overheats when driving and when I turn the AC on. I am not sure if its the fans that are not working. What could it be?

    I have a 2001 Toyota Tacoma 2.4L 4-cylinder and I can NOT find the coolant temperature sensor. I am VERY frustrated. Please HELP!

    you can easily test the ECT by running it under hot water, you will still get a reading than waiting for the engine to heat up.

    first of all thanks for answering my question.

    but my car is weird, it only overheats when am trying to race or just by going a little fast, because if i drive like a grampa all slow it doesnt overheat.

    thanks

    could be bad water pump, bad thermostat, bad auxiliary fan (if you car has it). It also depends how much it overheats. Just a little could be bad water pump, but it overheats way too much than my money is on a bad thermostat

    might be the heater core gone leaking. Depends on the car model, but some cores are more prone to leaks than others.

    my car has a coolant leak and it looks like it coming from under the thermostat housing but i looks and felt it and nothing was coming out….what could it be?most of the coolant leaks out on the driver side.but only after the car has ran for about 15 min and thats when the heat or a/c is on.

    Better make sure the fan runs when its supposed to, and if the thermostat is bad.

    if you have an answer to my question please comment back.

    i have a ford contour 96′ v6 and it overheats
    i already replaced the temp coolant sensor, temp coolant switch and radiator and it stil overheats, do you guys know what could it be ?

    another thing is a mechanic told me that it couldn’t be the cylinder heads cause the engine doesn’t throw the water away.
