1994 silverado dies when put in gear and push the accelerator. Otherwise runs fine, it is a 5.7L vortec. Have changed almost everything (complete tuneup} plus the throttle possession sensor. The funny thing is that is the code it is reading. I have put 2 new ones on it, checked all the wireing and plugs to it. I have one person telling me it could be the MAS or the pick up coil. Any ideas?

Interesting, to me it sounds like a weak fuel pump. You mentioned codes. What are they? Also, have you checked fuel pump pressure? Finally, did you mean the "MAF" and not the "MAS?

Let me know.

PS: Did you check for vacuum leaks?

Well after LOTS of asking around we found the right guy! It was the Motor temp sensor! Who would have thought! Tanks!
