I own a 95 gmc jimmy 4x4 and recently i had my fuel pump filter and sending unit replaced. it was running fine and then when i went to go take off to school one morning it was driving like crap. It feels as if the engine lost alot of power and while going 55 i cant get the rpms to go over 3000 while floored! my mechanic couldnt get any codes at all.
Someone please help!
