I have a 1993 gmc 1500 4x4, I replaced the engine a few months ago, and I am not getting any fuel economy, it is drinking alot of gas, I have replaced all of the sensors ie. Oxygen fuel pressure, engine coolant sensor. I cannot get fuel milage to rise, anyone have any ideas on what I can do? There are no codes in the computer! Please help!
