I've got a 1994 Ford Escort with the 1.9L and the 4EAT auto tranny. It's my beater daily driver that gets good mileage (~33 mpg give or take).
I've got a couple problems with it that I can't track down any further without a breakout box....
When the vehicle is cold:
-Starts fine
-Runs fine
-Idles around 1,500 - 2,000 rpm
When the vehicle is warmed up:
-Idles fine if you've been driving and come to a stop (~750 rpm)
-Runs fine (No misses, burps, hiccups, etc)
-If you shut the engine off, it will restart VERY hard
-Engine turns over fine, it just won't go. It'll stumble and hesitate until it either dies or finally catches and goes, then it'll idle around 2,500 - 3,000 rpm!
-Drive for awhile and come to a stop, it idles fine and runs fine.
I've been working through the pinpoint tests in the PC/ED manaul as far as I can without a breakout box. CKP is good, CMP is good, IAT is good, ECT is good, IAC is new..., have not tested EGR system yet. Cannot find any vacuum leaks, intake gasket is new.
Here's the kicker. I can't get it to spit out any codes when I do the KOEO test. I don't even think the PCM is performing the check. I'm using a jumper and a test light. When engine is warmed up, I shut it off, let it sit for 10-20 seconds, connect jumper and test light (test light comes on dim..), turn key on without starting engine, test light stays on. It won't blink, flicker, or do anything. I know I'm doing the test right because I went over to my 92 Ranger and performed the same test and got Code 11 (System OK). I haven't stopped in anywhere to have anyone scan it yet either.
I'd love to scream HELP ME NOW!, but the car functions fine for a DD right now. I never have to start it hot because it's either in the morning to go to work, or in the afternoon to come home, EXCEPT when I have to get gas. Then you shut it off hot and have to restart the effin thing. You end up flooring it while it's cranking over to get it to start.
Anybody have any idea what this could be?? Could this be a bad PCM?
Anything obvious I've missed?
