I posted earlier today for help on a 97 sl2 that is driving me crazy, and now my post is no where to be found in any section-what happened??

Hello all, I have a 97 sl2 with 1.9 dohc, and it has a major problem
right now. When cold it will start right up and run good, but to start it you must hold the throttle to the floor, and when it warms up if you shut it off it will not start back up. It will try if you hold the throttle to the floor-what it does after cranking for about 5-10 seconds is starts for a split second revs to like 1500 and the dies immediately. I have replaced the spark plugs, fuel pressure regulator, ignition module, map sensor, disconnected the battery to reset, new air filter, pvc, and probably more. Only things I have not replaced are tps, crank angle, computer and oxygen sensor....Any ideas?? Please!! Oh yes I did a block off plate for the egr_but still left the electrical connector hooked up-no check engine light either...The egr is the first thing I did.. Oh yes when it does start up it is running RICH-black smoke coming out of the exhaust, and stutters like it is choked and then it slowly comes around and revs up and clears out, I also disconnected the charcoal canister...I just thought of something else, the temp gauge does not work-stays on cold all the time. i wonder if it could be the sending unit telling the computer that the engine is cold and injecting extra gas-like the choke on???? |
If you posted it in the New Member Area ... I deleted it.

I think I have it figured out. The coolant temp sender is saying the engine is -8 degree celcius when it is about 80 degrees outside. I unplugged it and the car starts right up and runs great-just check engine light is on now..Got the new sensor going to be here in a couple hours...
|
FYI it was the coolant sending unit-replaced it the gauge works the engine starts beautifully cold or hot and runs and drives great...
|
Celcius you say .........
|
correct-with my nemisys obdll tester-that is what it read-like below freezing even when it was 100 degrees F here...
