Harper Posted May 6, 2010 Share Posted May 6, 2010 Paul, if you are still having your start problem, and want to check the B+ latch relay that I mentioned earlier, and if you have A/C, then there's a relay in front of the windshield washer reservoir. It's the cooling fan relay, and can be swapped out with the B+ latch relay to see if that is the culprit. The air bypass that the idle speed stepper motor is mounted into, could be gooped up with oil or carbon, and could hang the pintle and keep it form moving freely. The motor itself can be tested, but requires a special switching tool and careful handling to insure that the pintle is not extended beyond 1/4". I would check the relay first. I mentioned these as possible culprits to start with because the throttle plate is completely closed at idle, and the bypass passage is the only way your engine gets any air during idle or start(unless of course you depress the accelerator pedal). May not solve the problem, but it costs nothing to check, and you've eliminated that as a possible cause. Link to comment Share on other sites More sharing options...
