It will not go over 20 mph if I try to drive it and after computer diagnostic these are the error codes i get p1290, p1125, p1295, p1120, p1515, please help.

this may be the problem but a pro should do this as he needs to know the correct wire to do this. this is on our tips page it will probably take care of all the codes.
Just had the same codes come up on a 2001 rodeo I'm working on right now.

what I found while back probing at the pcm on the APS lines 1, 2, and 3 also TPS 1 and 2 is lose pins in the pcm connector. I shoved paper clips from the back side of the connector to tighten up the pins and the problem is gone.

hard to fined because when you back probe you make the connection but i found the wires turn in the connector to easy shovel a paper clip to tighten it up
