I checked for vacuum leaks around TB and UIM. Also sprayed a little around each injector. No leaks. I think I might be onto something. I remembered seeing my son with the ratchet on the nut thats on the end of the butterfly shaft. I think there'* a spring around it. When I had him putting the accelerator cables back on and tighting down the EGR shield I think he might have tightened down that nut which caused the butterfly to be partially opened when it'* idling. I held the cable guide and loosen the nut maybe a quarter inch and the motor is idling at 900 now 800 with it in gear. what do you think ? all I have to do now is get the codes cleared. This would explain the TPS error code too would it ?

It'* doubtful that explained the TPS code. It would simply think it was at part throttle. TPS codes are typically for low or high signals. Your stock TPS can be checked with an ohmmeter, preferable analog so you can watch the needle sweep for any dropouts.

The throttle plate being cocked part way open could very well explain your problem, as could the disconnected T.

FYI, none of the screws or studs on the TB are considered adjustable. None of them will do anything but make things worse. Air and fuel is managed by the PCM. Not by stop locations.

Will,

Thanks. The SES light went out when my son took it for another drive. I might tweak on it a little more to see if I can get it down a little more, but I'm thrilled to have it running again. All things considered this has been one of the best cars I've ever owned, and I've owned a few. Some of them a lot more expensive than the $7300 I bought this for back in 2001. So....a recap

New UIM, LIM gasket set, wires, plugs, TPS sensor, Oil + filter, Radiator, upper and lower hose, T-stat, coolant, O-ring set, rags, break cleaner, choke cleaner, torque wrench - $ 700

The car running, my son being able to see his girlfriend, the old man getting his truck back, and the wonderful help from this forum - PRICELESS !

Thats a wrap

Wow, that total went almost as high as a mechanic would charge. Hope that was a good torque wrench!

On a side note, can you gaurantee that nobody broke the two throttle plate (butterfly) screws loose from the shaft to the plate? If so, that is a very tricky little bugger to get realigned without any leak-by. When I do them, I hold them up to a bright light while I adjust the plate a little at a time, then lock them down.

That figure is a little inflated. I included the new Radiator and hoses. So $300 of that is the cost of those parts. Also the wrench was $80. It might be possible that the screws are bent/broken. I don't think he went that far with it. I'll check it out. thanks again.
