Ok so it runs alright but when I cruise around town the narrow band 02 says everythings ok but when I floor it under 6000rpms its so lean it doesnt even show up. I have no cel and vtec works after 6000rpms its runs great. With the stock (d16y7) ecu its fine, it runs rich at wot but theres no vtec. I have changed the iacv, throttle body including the tps and map, and I took the plugs and wires out of my d16z6 crx which runs fine and its not any better. What should I try next? Also before anyone says it I know the narrow band isnt great but it gives me an idea. Please help.

 

Anyone?

 

uhhhh how about the obvious right answer......... obd1 conversion harness and a P28 ecu.

good luck

 

uhh how about Ive tried that and it ran worse! I have a conversion harness and a chipped p28. Thanks for that obvious answer! Anyone else?

 

Can anyone tell me if there is a major difference between dx and ex harnesses besides the vtec,knock and 2 wire iacv? I just seems werid that no one else has had this problem and if they did they didnt post a solution. Someone please help.

 

Car runs fine at part throttle, anyone?
