Hey Guys, got a issue with my 99 Eddie Bauer.
Its a 99 EB, with a 4.0 SOHC
Bad idle when cold, rough and dies without your foot on the gas. When ambient temp is warmer when the car is cold, i.e. over 75, it is better at idle. When warmed up it runs fine.
This leads me to believe it may be the coolant temp sensor.
I have replaced, the IAC, the upper intake manifold gasket, cleaned the MAF, that was exciting, the car blew white fuel exahust for 20 min.
None of these had any effect, still idled bad when cold. The engine light was on, i did a code check, i have forgotten them now, but i think they were the bank 1, 2 lean codes.
I failed a emmision test once, with the light on. When warm the light didnt come on, so i went home, reset the computer and went out and tried again and passed.
The only thing i havent changed is the ECT sensor, which i have not been able to find for some reason, i looked for anything that looked like one when i had the upper intake off, couldnt see it, ARRGG
Where is this on the engine? Some say its by the thermostat, i cant see anything that looks like it by the thermostat.
I have a small coolant leak too, which also leads me to believe the sensor may be cracked or bad, which i cant find either.
I have a small leak that drips off the lower rad hose, i replaced the clamps and hose thinking it was bad, it still has a small leak coming from somewhere.
Any ideas??
