I have tried multiple of things. I put a new engine harness. A new p28 ecu. My distributor was new when I did the rebuild. I made sure all of the wire plugs were in the correct spots. I did the timing 3 times to make sure it was correct. I need help!! I don't know what to do any more. It seems like I tried everything. It's a obd1 eg coupe with a gsr swap. I have a d15 harness and planned on running the vtec solenoid and pressure switch to the ecu once I got it running correctly. I have a check engine light and already did the pin test. It's throwing 7,8,10,16,19,22 and 41. I ran it before with out the oxygen sensor. It seems like it back fires when I floor it and Boggs down and tries to die.... Please help me out!!!

 

do you have the tps and map plugs switched? here is a list of obd1 codes

Is the tps calibrated?

 

You are throwing nearly every major code in the book, and you wonder why it's not revving??

Code 8 is enough to put it into limp mode, preventing rpm's over 3000. My guess is you have some major wiring issues. Did you cut *any* of the harness wires? Have you triple-checked your 3 major grounds (battery, transmission, thermostat)??

BTW that "new" distributor could be junk if you never tested it - new doesn't mean usable. A large amount of cheap china-produced distributors are just expensive headaches.

 

I bet you switched the TPS, MAP, and the IACV connectors....google the wiring colors and match them.

 

I'm using a d15 harness and wiring vtec myself. I have it running. Just has a minor revving issue. I keep timing it. Which I'm pretty sure the crank with the pulley on you time it by the 3 line mark with the one in the middle. I collaborated the tps and it still does the same thing.
