Check fuel pressure regulator. Pull vacuum hose to regulator and see if it has fuel in it. If so replace it.

Without knowing your model and year and engine, check and make sure no wires are damaged, while running unplug the alternator and see if the problem stops a short inside the alternator can cause an electrical current change causing the problems if so replace it, is the air filter dirty, if so replace it, and lastly inspect around the intake for any cracks, you can use a can of starting fluid, while its running spray around the intake and see if it idles up, if so look at where you sprayed it and see if you can see gap or broke vacuum line.

RMPs won't drop on 97 SL2


on the s series it was very common for carbon to build up inside the idle air control valve-IAC valve.there are too expensive and are easy to fix-buy the part so you know what is looks like the look at your throttle body(follow your air filter box tube to the top of the engine-the throttle body)the iac is right there.

you have a 1.8 liter turbo engine correct? it is the water pump that is driven by the timing belt. 100% positive this is correct i have replaced countless water pumps for this reason. the reason it overheats while driving is becuase the splines on the water pumps plastic impeller are gone and it is just freewheeling on the pump shaft. at idle the pump spins slow enough to get the impeller to turn. very very very very common. replace water pump timing belt and tensioner.

Most likely your throttle position sensor is faulty. You could have a vacuum leak as well. Most probable cause is a bad sensor. Is your check engine light on? Have you checked your engine codes? You can go to autozone.com and register for full free online repair manual.
