I drive a 1987 toy 4x4 truck with a 22ret. Yesterday I attempted to adjust the TPS, i can only imagine that I did it wrong. When I was done the truck drove the same. The reason I adj the TPS is because I seem to have been getting poor MPG and yes I have taken into consideration that I am riding on 33's. Today when I cranked the engine it ran fine, I checked the codes and now I am getting a code 14. The book says that code 14 is a turbo pressure problem. I am at a loss. I removed the EFI fuse for about a min and the code still shows. Can this be a problem with my half @%$ attempt at adjusting the TPS or could I have really screwed something up.

Disregard, I let it warm up this time, pulled the EFI fuse after it was shut off and let it sit for a few minutes. I then pulled the codes and it now reads normal.
Sorry.
