ok, i completley cleaned my throttle body and components to the t. idle is still low, but the engine doesn't cut off. that's an improvement. i got code P1297 Manufacturer Control Fuel and Air Metering. does anyone know what causes this? now i get code P0108 MAP/BARO Circuit High Input. It feels and sounds like my engine is getting uneven fuel mixtures. the engine stops reving around 3500RPM's, but after a few seconds it increases. it sounds like it red-lines at 3500 but just for a few seconds. anyone ever had this happen? thanks!

 

check the Throttle Positioning Sensor?

 

yeah, i did that. is there anything special you have to do before you install it? it just goes straight in, it only rotates one way, so i imagine it can't be installed wrong. maybe the computer got fried.

 

You still got the stock cat in there?

 

nope.

 

it all started after i got a whole lot of muddy water under the hood. i figured something shorted. i replaced the tps, and it's idling between 1500 and 2500 rpm's.

 

Pull the Jet Module and see what happens.

 

i pulled it after the problem started. it ran fine after that. how would i reset the computer?

 

Disconnect the negative battery terminal for 10 minutes or so. Some people say you have to turn the key to the "Start" position for a little bit but I've never done it that way. After you hook the - terminal back up it should take a couple hundred miles for the computer to relearn your truck and driving habits.

Then retune your radio pre-sets ... [:@]
