Northern New York | My son recently bought an 2008 chevy one ton with the duramax engine. 107,000 miles.
Truck runs great except when pulling heavy loads ( 25,000 lbs gross).
Truck without a trailer runs great, truck with empty trailer runs great.
Under load it will occasionally go into "limp" mode and throw code P0087, which is fuel rail pressure too low.
Took it to our local Chevy dealer, they scanned and said two injectors were bad, so they changed them.
Didn't help at all.
Any ideas?
Unfortunately, he bought it out of state and place he purchased from has basically told him he is on his own. | |
