hey everybody, need some help with my 87 tII. i've got a hesitation that a local rx7 guru said is a result of hooking up my af ratio guage. he said the fix for it is to locate the ground for my ecu and splice into it and run another ground. need help locating this ground wire.
thanks, josh

 

does it happen at 3800rpm? that is a common problem. has nothing to do with the gauge. there are lots of write ups on the net on how to reground it. don't have any handy though. try doing a search on the forum for past topics.
