...terrible at idle..Any soluitions .THKS? Has to be a bad sensor because it don't do it all the time only when the motor grabs a little water temp. then chk. eng. lght appears then runs bad at idle. If you fuel up on it, it will miss a hair then clears up until the motor comes back to idle. Cleaned idle control valve, chk plugs, wires, fuel filter and pump all good . Thing got me frustrated. Any answers welcome
