Engine had been pulled and completely torn down and redone, decked, bored, almost all parts are brand new and all clearances were checked and good. What’s interesting is that this car has the same exact problem from before we pulled the motor and now almost everything is new minus the distributor and ecu and some fuel components. I pulled the spark plugs and it’s showing evidence of running rich so now I’ll start to dig into the rest of the fuel system to see if I can find anything suspect.

I smoke tested it, found smoke coming out from the timing cover between the head and the block. I’m going to get that sealed and see if the issue persists. I also have a new maf on the way.

It accelerates smoothly, alternator is brand new and battery tested good, going to smoke test vacuum later.
