having touble with my 95 Camaro. its running rich around 11.8 afr at open loop. will rev up but if I push the throttle quick it cuts out. once the car warms up the reving isuue goes away but then the afr drops to 10.5 or so. I know I need to be around 14.7 at idle and 11.8 on the top end. I replaced the 02s checked for vacuum leaks couldn't find anything. I got the tunercats software to make adjustments and eehack to data log but have never used either. what should I look for in the datalog and where would I make the changes in the tune? I am wondering if telling the pcm there is a larger flow injector if it will correct and call for a smaller pulse and compensate to fix the problem. I am going to replace the header gaskets Tuesday night and check the thermostat. I really want to learn where to make adjustments in the tune to get the car running great not just running.
