Engine Performance problem
1994 Chevy Truck V8 Automatic
hi, I just put a newer motor in my 94 chevy pick up. I used a block from a 97 vortek, heads from my original motor (they were redone at a local machine shop) and I used my throttle body intake. I had the complete 97 vortek with wiring harness, but had to use what I did because my 94 wiring harness didnt have all the sensor plugs the 97 did. Any way got everything in and connected and timed and everything seemed cool, except the service engine soon light was on, not the check engine light I had seen many times in the past, when the water temp. Was too high or etc. The truck seems to be fine except it doesn't accelerate as it should. Might it be in limp mode or default mode? And why? All the sensors seem to check out ok.
