Changed Plugs & 02's
 

I just changed my plugs and front 02 sensors at 75K. Truck runs great, EXCEPT now when I come up to a stop my idle drops to below 500 and almost stalls. It also does it when i've let off the gas, slow down and turn, to a point where the power steering seems slugish. Could the new plugs & 02's be the cause? One other thing, after the work was done I put my Troyer tune back in and have gone back to stock. The low idle is there in both. Anyone with some ideas?

It may have to re-learn the new plus and 02 sensors, how many miles have you driven it?

cant see it being the plugs unless you put the wrong ones in, but it could be the o2's or you missed a wire putting the intake back on

did you gap the plugs?

Problem solved!!! Cleaned the throttle body over the weekend, WOW what a difference. I dont know why the idle problem started after the plugs & O2's were changed but now the truck is running like it should. Idle is at 750 when in park and 700 when in gear. Put my tune back in and its fun to drive again. I guess I'll wait on the 09.

What's the best way to clean out the throttle body? Should this be done on a regular basis?

I just pulled off the air cleaner housing and used a carb/throttle body cleaner and a toothbrush. Then wiped it down wit a clean rag. As far as on a regular basis? I'm going to since it was so easy to do.
