what do you guys do to get a little power out of these engines.... i have a 1998 gmc jimmy 4x4 with a 4.3l i have a cold air intake and this thing seems weak to me. For the size of this engine it just seems like it doesnt pull as hard as it should. Also i have no s.e.s lights on and shouldnt have a mechanical prob. I put on new plug, cap, and wires also. Is there anything economical that i can do to get some power?
Also i am getting about 280 miles per tank if i run it down until the low fuel light comes on.....
