Howdy all,
Been awhile since I have posted. Tried calling a few in the know people for advice and I myself am a fair mechanic, but to no avail. Truck can only be started with your foot to the floor (sometimes....when it is cold it seems to start easier), it will not idle and will die each time you put it in gear. You have to rev it up full blast and shif it into gear to get it to go.....not good!
None of the following changes have cured the problem.
1. Swap out TPS with new unit
2. Replaced IAS with new unit
3. Swapped out MP computer for stock one
4. Cleaned T-Body (B&F Stage II)
5. Checked all vacum hoses and electrical connections
6. Replace ignition coil
7. Checked all SP wires and plugs
8. Replace upper rad hose (found a leak)
It throws the following codes: 12, 22, 37, 55. But I don't see how any of them affect the idle circuit. Check engine light is on.
TIA for the feedback!
What am I missing here?
