I got a 88-91 b16 in a 89 si hatch, has anyone ever ran into a problem running the pw0 ecu? On the freeway at cruising speeds (70mph) with light throttle seems to feel like it accelerates and deaccelerates on its own? It only does it cruising on the freeway at light to moderate throttle (no load)?
Other than that it runs great and pulls good....No Check Engine light or anything? Please help.
I suspect the ecu?

 

check your coil it cold be getting weak

 

Yeah its normal from what i understand. I have 3 friends that run the PR3 and PWO and they all have it around 70 mph. I dont know what the problem is though. or how to fix it though

 

Thanks....I wonder why the obd0 b16 ecu's do that??
