Hello Everyone
I've looked and searched and generally kind of poked around here for a few hours trying to find something that could help my friend.
He purchased a nice Custom Chevy truck that someone had put a 94 LT1 Corvette motor and 6 speed transmission into it. The original owner had replaced a bunch of head gaskets and they would immediately blow one after the other and he got pissed finally and sold the truck to my friend. My friend had the Aluminum heads surfaced because they were warped and bought some new head bolts and took care of that problem.
The truck runs fine at normal operating speeds but when you get after it it pings really bad. He says it will still blow the tires off the truck through the gears but it just pings severely. At part throttle it's fine. He scanned it and saw about 38/40 degrees of advance at idle which seems high to me. He says that it cranks as though it has to much initial advance too. The truck idles with a very fuel rich smell. The truck does not have a working MAF Sensor but is setting no codes. The truck has no Knock Sensor. No Codes. I'm not sure if it has a working o2 sensor or not. No Codes set.
He said the computer had been sent by the original owner to a guy named Mark at Street and Performance. Can some of this stuff be programmed out so the engine just runs open loop all the time? I'm just trying to help him get his truck running properly. Any help is appreciated.
