does this sound like a Bad maf? My car just had a stroker motor installe. Ever since it began to slowly run like crap afterward, it was on and off. Then it started all the time. It will idle, but when you give it gas it falls on its face like it isnt getting spark or fuel or something. I was abkle to take it to the dyno to get the air/fuel right and I hoped that would fix it but it kept dong it afterwards and finially crapped out and runs liek crap all the time now. Its so bad it pretty much wont run.
Hptuners picked up a 'low voltage to maf' code and a "throttle position sensor code". I replaced the throttle position sensor and the problem is still here.

Just because there is a TPS code doesn't mean the TPS is the source of the problem, you need to find all related wiring and components with the MAF and/or TPS to figure out what is actully causing the problem.

Well its not the MAF. I am at a point where I dont know what to do. I doubt this will be the root of the problem(s) but Im going to pull the spark plus tomorro, it sure is running like most of if not all of them are fouled out.
Who did the tune for your stroker ?
If the VE and MAF tables are far enough off from eachother the result will be a crappy running engine, TPS and MAF codes. Nothing to do with sensors or wiring... Just a thought.
