92 chevy with vortec heads
I rebuilt my engine. Put bigger cam and crank with flat top pistons and put vortec heads on it with new aluminum high rise intake replaced the map sensor, tps, temp sensor, spark plugs and wires new distributor, cap, and needle and rebuilt the throttle body and it still isn't running right. Is runs very rich burn way to much fuel and burns the plugs soon after I start it. Please help. Idk what else I can do.

Re: 92 chevy with vortec heads
You may need to have the eprom reprogrammed to adjust of all the changes you made to the engine. I have never had to adjust anything on a TBI, so nmot even sure what adjustments are there. I moved this to the main area to get you some more looks hopefully

Re: 92 chevy with vortec heads
You need to contact Brian Harris at tbichips.com (Harris Performance)
tel:336-471-2827. You need him to burn you a custom chip. Have all your info and give him a call. Did you put in an adjustable pressure regulator and a high performance fuel pump. |

Re: 92 chevy with vortec heads
I checked my plugs today and all are fouled out with serious black substances on the except for my 6,5,and 7 plug they weren't as bad but I have very bad miss fires and sputors and flames coming out of my tbi when I throttle down on it. Any suggestions?
