SOURCE: P0336 Code
The code P0336 is crank shaft sensor performance code.The sensor could be faulty and not picking up a good signal.The after erasing the code,the problem still exists ,so it is then a pending code and when you shut the car off and restart it the code reappears.Just another idea here ,if you have not had a tune-up recently(plugs,wires,airfilter,etc.)you could get unwanted codes and your engine will not perform as it should.This could cause poor gas mileage as well.John.

Normally if you can't get a reading from the ecm the ecm is dead, and goes to default mode meaning it will run ok but is at base timing and won't kick in to closed loop having the 02 sensor controlling fuel and timing, they did this because if the past if the ecm failed the car was a pull toy so you sat on the side of the road so the ecm could be bad. You could have someone do a pin out on the ecm but it would take more time than it would cost to replace the ecm.

When I see all these codes i instantly think of two things. Vacuum leak especially intake manifold gaskets and Mass air flow sensors. Spray the engine with carb cleaner when its running and see if you get it to rev up,run rough or run different. Next unplug the MAF and drive the car, see if it runs normal.

Possibly it's the Idle Air Control (IAC) valve. It is attached to the intake manifold. It's supposed to open and let air in when the the throttle is closed. The simplest way to test it on this car is to remove it entirely. It is just held on to the intake manifold by a few screws, and removing it leaves an opening in the manifold to let air in. If the car idles smoothly with the IAC removed, you'll know there is a problem either with the IAC itself or with its circuit. You can test the IAC with an ohmmeter between the center prong and the two side prongs. Neither one should be an open circuit. You can test the circuit with a voltmeter on the harness, between the center slot and the two side slots. You can refer to www.hmaservice.com for the complete details, available free with registration. Possibly it is clogged and you may just need to clean the IAC with throttle/carb cleaner. Let me know if this helps.

Testimonial: "I found that the air control wasn't it, I found a plug wire that had a worn spot in it. Thanks for the help"
