My truck seems to run ok in park, with a little variation of the rpms. But when put in gear MOST of the time it idles way down and dies. I can usually keep it running at stop lights with my foot on the gas a little. Then again sometimes it idles down to much and dies. Isn't constant, doesn't happen at every stop. Engine light comes on once in a while, but goes off either by itself, or when you turn the truck off, turn it back on and its gone.
Only one current code came up : 636 TOT sensor voltage out of range. Several cm codes were present. :
O2 rich right side
Egr below min volvtage
Fuel pump circuit failure
Converter clutch lock up error
Act sensor greater than self test max
Replaced the IAC, TPS, fuel filter and air filter.
Cleaned the thottle body and checked fuel pressure.
Any help would be appreciated. I didn't know if the cm codes were something I needed to worry about. Although I disconnected the battery thinking they would go away and hooked it back up 20 min later. Codes still there
Thank You
