well i finally got around to doing it! thanks, i actually used a kids toothbrush & some rags. the TB def needed the clean. damn the black stuff really runs all over after you spray it with the cleaner!!
yeah i did change out the TPS, IACV(wow! was this was in bad shape!) & PCV too while i was at it...
btw, what sensor is attached directly before the 4.7 resonator box??(is that the right name??). i thought it was a MAP sensor & ordered one(rockauto) to replace. but its def not the same part.
now ive gotta figure out how to clean my intake sytem behind the TB. i would love to try seaform, but shipping quotes are 6x the bottle cost!!!
