hey guys, when my jeep is first started, it has a rough idle, it will shake the whole jeep, but after it gets warm and hits closed loop, idle is nice and smooth.
Also when i slow down at a light, the idle seems to get very rough until it shifts into 1st gear again at a stop and then it smooths out and runs fine ....i cleaned my IAC really good but wondering what else could cause this problem ?
my fuel pump never drops below 32 psi of pressure, its like the idle falls too low when slowing down but then recovers when fully stopped and in 1st gear.
I also have a new TPS sensor from carquest.
