Question about Chrysler Cars & Trucks
Replaced alternator and now car starts but idles at 2500 rpm, bogs and misses when you give it throttle and sets off codes P0201 & P0202. Both #1 & #2 injectors and TPs sensor have been replaced with no effect.
What is sensor p0201 and p0301?

A faulty IAC would cause a random misfire rather than a misfire in a specific cylinder, as would an intake air leak, both of which would cause a high idle amongst other things.
Run the engine until its good and hot, disconnect the injector harness plug so the injectors are disabled, remove all the spark plugs, disable the ignition by unplugging the wiring connector(s) from the coil pack(s), and then carry out another compression test on al the cylinders.
If the compressions are now all relatively the same then you very highly likely have a faulty injector in cylinder 3.
Very best regards

SOURCE: High idle at starting
Sounds like you have a vacuum leak in the air intake side. Check all your small and large hoses around the throttle body. Also check your idle air valve....cylindrical device connected to the the air box at the front of the engine.

It sounds like you have a vacuum leak or intake gaskets leaking. Try this. Start the engine and let it reach the idle it want to go to. Get you a can of Brake Clean and spray it around the intake manifold (it on the top center of the engine, you may have to removed a plastic cover) If the engine idle changes up or down then the intake gaskets are leaking hence your vacuum leak. I hope this will help you.
