Used the MAF that came with the kit, so have no idea how many miles were on the TB or the MAF. And no I wasn't saying the plate itself was cleaned by the FI cleaner stuff, as that's the air control, I was just commenting mainly on the the intake after I put the new tb on, and then it started acting up in the cold and started thinking it as a system. So started with the tpo area and down. My next go was to replace it with the maf I had and still have. Just trying to figure out where the hiccup was in the most logical and inexpensive process is all. The question was raised if it was fixed, and as of now it seems to be. There was just this hiccup that perhaps was in the feedback system for some reason. But it had to do with the replacement, the engine was going I think really rich at those times
