Check engine light?? 94SE
Would any check engine light keep the engine from going into closed loop?
Seams I am having problems with the 94. I can't get a scan tool to work and thought that I could just figure the thing out by checking everything. What I get is if I clear the coads the engine will start and run for about 10 sec and then the check engine light will come on. If I don't clear it again the Check engine light will come on at start up and stay on.
What codes will retard the timing? The power is low and has that sound of bad timing, but after 3000 or so RPM it will take off like new. We tested the ECM as a OBD II, but after looking at past posts I think I have a OBD I, with the OBD II, conector??? (is this true for 94?) How do I test this thing?
Thought that I had this thing figured out last week because my engine fan was running after cold start up. But after finding the problem only being a bad compressor head switch and repaired that I'm back to nothing!!
Does some one have a list of codes and what effect it will cause?? Like I said the engine sounds as if the timing is way-slow. The only mod is a custom chip that the engine ran great on before this. I do have the computer on the floor to check sensor OMes.
