I have a 2000 Bravada , realy like the truck, engine needed valve job, so we just found one less miles ( 49,000 ) in a 2002, well garage did it, and now dosent seem to have power like it did, and the oil pressure. At running speed stays at 40+, but when you come to idle or slow down very much it goes down, about half way, 20 - 30 is this normal ?? I always thought , with old engine, it stayed about 40 all the time, even at idle ?? Please let me know.....other Bravada owners or ??
Thanks , Bill W.
