Replaced the pre-Cat O2 as per your advice and boom crappy idle gone! Shes purring like a kitten now!

Changed the tranny fluid too with some brand new ATF +4, changed the Diff fluid and the Tcase fluid too. Its like a brand new truck.


I was having an issue where after a cold start it would run good for about 2-3 mins, then start to idle really crappy and almost die, after about a minute of this the idle would sort itself out and run normal. Replacing the Pre-Cat O2 resolved the issue.

 

Excellent. Glad ya got 'er fixed.

 

Love it when people post updates and fixes. Glad it's good to go.

 

Edited original post with details of the problem I was having.

 

yeah heyyou has already helped me tons just in the 1 week i've owned my truck!

 

THREE CHEERS FOR HEYYOU!!!!!!!!....... literally i suppose

definately need to change my precat o2 sensor too, looking kinda crappy and rusty!

 

I think I am going to get new O2 sensors on my next cap/rotor change. Plus some Magnecor wires and pulstar plugs. Gonna be an expensive tuneup. Damn Cali trucks and their 2 pre cat O2 sensors.
