H23a 11.5 comp pro1 cams tuned on Hondata.
I had it tuned perfectly, but it started getting lean at times and bucking at cruise. I replaced the entire fuel system, sensors, a lot of wiring, ECU, hondata, distributor, checked tune multiple times, re-tuned, had professional check tune. I think something is causing interference or back-feed to ECU but no Check Engine Light. However, it'll get a solid Check Engine Light with chrome chipped ECU. I'm lost and I need help. Relay wiring diagram would help.
