well, im posting this, but i feel you have an engine problem, cause you posted a thread today on how to break in an engine, then you posted another about low compression, now your compression is good ??? ok, anyways, if you replaced your tps, then, you have to set minimum tps with a scanner at a dealer, or an independent shop with a scanner tool, (there is no other way around this) then, set idle at around 3200 rpm out of water, then it should be around 1500 plus or minus 150 in the water, but if you have an engine problem, you are wasting your time .........
