Ok, cleaned the TB, omg was it black and bad, cleaned the sensors too, except the tps which was clean. (not exposed to any air flow, no way to get dirty?) I noticed better throttle response at take off, at first it would bog down then sort of launch, now its a smooth rise in rpm. Gona wait on the o2 sensors since they are 50 a pop

 

Usually if the o2's are bad it will throw a code. Nothing to worry about really

 

way to go man, im gonna probably do that on mine before i reinstall the motor in to the truck.. although mine still has more than enough power to break the rear wheels free and roast em..

 

I agree with dodgeramguy85.But here is something you may try with the o2's if you think you are having issue. Take them out and set them in gasoline over nite. This tend to lossen up any carbon build up on the tips and clean in the morning and re-install. I have some success this. Whether it works is a matter of opinion. However when you looking at $200+ for new ones this may be worth a try.

 

some chrysler engines like a wider gap than stock. i tryed this on 318,360 engines i set the gap at .045 not sure it helped. if you go to wide the engine will stop firing at high RPM, but not low RPM. but if it miss fires any dont run that gap, for any RPM. the best way to experiment is try one cyl first. that way if it really hurts its only one cyl, and you can get back home. been there done that.

 

i can see and understand the sicence behind that, when i did my tune up back in august, i used the Bosch Platnum +4's and the truck absolutely LOVED IT.
