2003 silverado starting problem

2003 silverado starting problem

Postby Kmorc [OP] » Jun 18 2012, 1:51am

My father has a 2003 silverado. It has a very rough time starting after sitting for awhile. To get it to start you have to hold down the gas peddle. Received the message, "Reduced Engine Power" and it wouldn't allow me to accelerate over 15 mph (this was all accompanied by my check engine light). Attempted to start the truck again today, same problems (had to hold down the gas to start the truck), minus the "Reduced Engine Power" message. Turned the truck off and immediately restarted without a problem. Allowed it to sit for a while and I was back where I started (my check engine light did not come on today, however, I experienced the same problems from yesterday). The truck was just at the dealer for this issue and they put in a new fuse box because mice had made a nest in the old one. The truck only has 30,000 miles on it and it pretty much just used for plowing and hauling on some occasions. He is contemplating getting rid of it because it such a headache. Any help regarding this issue would be greatly appreciated! Thanks, Keith.

Do you have the actual code that is set when the check engine light comes on? A lot of times the "reduced engine power" has to do with a throttle body problem.

Don't know the code. Check engine light never comes on when he takes it to the dealership. Go figure... He talked with A mechanic from the dealershIp today and they said it could be the accelerator position sensor.

Try and have it connected to a diagnostic scanner and see if it has any trouble codes in it's history. That could help narrow the problem down a bit.
