That sounds like the problem I had with my '93 SSEi just after I bought it a few years ago. It started and idled well when the engine was cold, but sometimes not when the engine was warm or hot. In my case, the throttle body needed a good cleaning, and I had to remove it to do it right.


When the problem occurs, don't let the engine idle at low RPMs - it'* not good for the engine'* longevity; until the problem is fixed, tap the accelerator to increase the idle speed a little, just like you mentioned.

Check for codes first buy grounding A&B terminals on the ALDL underdash on drivers side. Count flashes on Check engine light. No codes,= check fuel pressure regulator

hope this helps

Is there a how-to on cleaning the throttle body and is there just certain stuff you don't use? what about that screen that is there what is it for and do you clean it while stil on the car or take it off?

thanks

If the buildup isn't too bad, you might get by with a bottle of fuel system cleaner in the fuel tank, but that didn't work for me.

There might be a write-up about throttle body cleaning in the techinfo section. Other people may have found a way to clean the throttle body without removing it, by removing the MAF screen and cleaning the inside, but I took it off, removed the MAF sensor and screen, and cleaned it with an old toothbrush and spray carb cleaner.
Note: You can remove the MAF sensor and IAC sensor and reinstall them without worrying about mounting adjustments, but don't remove the TPS sensor unless you plan on and know how to recalibrate it when you reinstall it - the mounting screw holes on that part are adjustable to calibrate the TPS voltage within the normal limits.

On your SE it might be easier than it was on both of my supercharged models. Mine took about an hour each.

Okay, just take a minute here and humor ol' Andy, will you? Lift the hood, pull the vacuum line off the %$&* fuel pressure regulator, and just tell me if gasoline leaks out. I will feel _so_ much better afterwards.
