I would suggest to get a scanner connected to the car to retrieve any saved error codes in the computer box. Some shops would let you borrow their scanners.

As for the causes unless an error is detected there could be several issues that may have caused this. Observe if there is lagging when stepping on the gas while the car is in idle or at parked. Observe also if there is inconsistency with the idling. This may be just caused by holes or leaks in the air passage from the air filter to the car's intake or the idle air control valve may be dirty or faulty. Check also if there are leaking vacuum hoses or worn out ones.

If this only happens when in gear check first the fluid if you need to add more or needs replacing. The solenoid inside the transmission may be dirty. Or possible that the torque converter may be bad.

I have a same problem. need help

it could be a faulty sensor on a wheel assembly, the dealership would be able to scan the abs system and give you a fault code, a local auto parts store may well be able to do the same.
I'm sorry for asking, but did you check the fluid level and bleed the brakes? just a thought
hope this helps.

Hi there?
The temperature sensor causes this sort of problems. when the engine is hot, disconnect the temperature sensor and see if it starts..

You will have to check the voltage of the motor.With the window switch depressed check the voltage at motor.It should give 12 volts.If there is no voltage, then its motor causing the problem.But if there is proper voltage, then its regular causing the problem.Also check and confirm, the window switch is receiving the voltage and switch wirings are intact and not getting loose.In the regulator there are metal brackets, they tend to get bend and this blocks the motor from running.So check the brackets too.If they are bent, then get it straightened.-------------If the regulator checked faulty,worn out bent ten it has to be replaced.-----------

Sounds like this may be a "glitch". The maintenance items will not do this but it never hurts to keep up on it. The brake/tail light warning is 1 of 3 things; 1. faulty bulb/s, have some one turn the lights on and then have them step on the brakes while you look at them from the back. 2. Inferior quality bulbs. They will work in the system for lighting but will keep triggering the monitor/warning indicator. 3. Faulty BCM (Body Control Module), but not likely.

mostlty if you clean the nozzle from outside by a needle or something like, but make sure there is a water in washer tank.

If you bypass the pressure sensor at the dryer, the AC compressor should kick in. If it don't not turn on then your compressor clutch is bad.

driving with low fuel is never a good idea. It can allow all kinds of contamination in the tank be picked up and sent to the engine clogging the pump, and injectors.
I'd start with a good fuel system cleaner like Tecron. add the contants of the bottle to the tank then put at least 12 gallons of gas in the tank. You may need to do it a second time especially if you notice improvement but it's not yet up to par.

Hello,

The fuel filter is the silver can thing that is behind the mini radiator which is a fuel cooler.
The fuel filter is a round soft drink can size unit.

To locate it, look for the main black plastic air inlet thing leading to the top left of engine bay which is on your right hand side as you face the engine. It leads to a mini radiator looking thing which is a fuel cooler. Right behind that you will see your fuel filter.

Take care and good luck

This is done for performance and geometry. Mess with the sizes, you will notice handling issues. A lot of higher end performance cars will do this.

check oil level, oil expands at higher temperature.

yea go to a local autoparts store and purchase copound 2-26 its an electrical contact cleaner, spray up the socket and clean it out with a paper towel.
see if that helps

Did you check to make sure all of your spark plugs are in their holes?

is the catch ok and not been knocked foreward by slamming the tailgate too hard ,striker /fastener /holdinf pin/ ---use own description for the bit in the floor that tailgate fastenens too
