I have a 1992 Eclipse 1.8 NonTurbo. Since I have owned it it has seemed to have an intermittent miss. Yesterday I was pulling away from a stoplight and the car felt extremely down on power and was smoking and backfiring. The smoke is gray. After getting home , I noticed how gassy the exhaust smelled and I could even see raw gas blowing out on to my driveway. I have done a compression check recently and all cylinders ranged from 190 to 210 lbs. I do have spark and I have used a noid light to check to see if the injectors are getting a signal.
This is where I beleive my problem is. #1 cylinder the noid light is on constantly (may flash occasionally), #2 is steady off, and #3 and #4 are a normal flash/pulse. I used a screwdriver as a stethescope to listen to see if the injectors were clicking and #3 and #4 were clicking.
When I unplug #1 the smoking diminishes greatly but the engine RPM does not change. #2 does not affect the RPM or the smoke. The resistance of #1 and #2 injectors measured below spec but that does not explain the noid light not flashing.
My problem boils down to how can I check to see if it is the wiring, the ECM or the Injectors? I have very little experience working on fuel injected vehicles. I dont even know where the ECM is on my Eclipse.
Help me if you can!
