tps bad?
ruff idle/poor acceleration...got codes 41(02 sensor),63 tps signal too low. got out the old Haynes to check tps. at idle-.945v full open-4.5 volts...within range according to the book. It also says to check the resistance...said it should go from 3.5k ohms down to around 350ohms wide open. Mine never moved from 3.5k......is this possible? For the voltage to be right and resistance off? Kinda thought they moved hand in hand.

tps bad?
I can't imagine the tps causing it to idle rough.Not sure about acceleration.Sounds more like air idle bypass valve or the egr valve to me.Sure you didn't get some bad fuel???Hope this helps.
