hi peeps im new to the forum. sucks my first post will be about help ..... as i cannot find an answer. this forum as alot of knowledgeable people as well as faqs. hopefully some of you may assist me on this.

i have a 91 crx dx automatic. ive just done a mpfi swap on it. however the issue is this. that runs bad. its also throwing a code 9. now the weird part is, is when i reverse c1 and c2 the code goes away. however romping it for a few minutes brings the cel back.

i know the wires are correct. ive done well over 10 mpfi swaps. solder heatshrink etc etc even doubled checked for broken connections. ive tried 2 different known working ecu's as well as 2 known working dizzys. as my other auto mpfi works fine.

the only difference between the 2 cars is my 88 auto has no egr and this one does. well not anymore. is it possible the pre exsisting egr circuits are causing this problem? or has anyone ever experienced on an 91 auto egr dpfi to mpfi swap. after 5 days i have not been able to come up with a solution.

also the timing is dead on as well...

hopefully someone here may know

thanks for your time
