Boggled ~ engine missing when driving

Sorry to revive an OLD post like this but I can't believe the things people come up with as far as "What do I do"? In this case, I think I would check the "E-F" gauge and make sure it's leaning a little to the right of "E". I'll be so damn glad when the new title comes in for my recent out of state purchase so I can unload it rapidly. Already have two offers from complete strangers to buy this gas hog, even after telling them what my actual fuel mileage is and they approached me just because of how clean this truck is. No 4-sale signs on it or anything. (15 mpg). 2000 Chevy 2500, 126,000 miles, old body style,(88-98?) 5.7, 4 speed AT, 3.73 rear end, 2 WD, absolutely NO rust, and this truck has NEVER been in salty winter time conditions as far as I can tell. Came out of northern Texas last July to Pa. I don't believe the previous owner drove it at all last winter in Pa. I wet my finger and rubbed it UNDER the lower door flaps and tasted "NO" salt. Kinda hard to get ALL salt residue out of that area. I've had this thing for 6 weeks now and have put 1,500 miles on it. Kept track of fuel use since day one. Best I got was 15.3! Damn near $400 in fuel makes me think that I could be riding in something a lot more comfortable and hire someone whenever I need something hauled. Sorry for the rant and I really love older trucks but this rough riding SOB has really turned me off! Hate to go foreign or hybrid but think of all the bucks I'd save....Naw, can't do that, I just need a smaller truck that gets better mielage. NSG

Uh, the original post/problem was almost 3 years ago...Hope he got it running by now....nsg

j cat, Took your advice and replaced the 2 upstream o2 sensors. ($168). I'll have to wait a while to get an accurate mileage reading. This is gonna be one hell of a bargain if I decide to sell it. All I want is what I have in it for cost of truck and parts , I'll chalk up and eat the labor due to it being a learning experience! I'm retired and have nothing better to do.(Well, I do but she doesn't) Other repairs include: front end alignment after $950 worth of Michelins all around, turned rear drums to get rid of pulsating brake pedal, new front air dam, (don't know if it had one originally), got ALL lights working, DRL's, interior, cargo, new tranny tailshaft seal, K&N Air filter, polished headlights so I can now see GOD if they are on hi-beam, been working on lowering tire pressure to get a better ride. Truck is still stiff and I haven't had a load in it that weighed more than 10# yet. Sits real high on it's own and get a lot of steering wandering in crosswinds. I'm thinking the camber needs to be something other than what the manufacturer recommends??? The radio wouldn't put out anything other than AM and the cassette part was dead so it now has a new AM/FM/CD so me and Patsy Cline can go down the road together...Did I mention the part about it being ABSOLUTELY rust free???? Not even where the outer door skin attaches to the door shell!!!!! If I was really ambitious and was gonna keep it I'd strip it back down to the frame and rustproof everything. I'm starting to feel guilty about even thinking about driving this next winter. Whether or not I keep it I'll probably get it "Fluid Filmed" in the next few weeks. nsg
