Okay, can't give you guys a code, my truck is conspiring against me to keep me from getting one. It's a '99 2WD with the 3.4, 187,000 miles, lately, did the valve cover gaskets, plugs, coil packs, cleaned the throttle body, and changed the old cracked hose up top that connects to the throttle body.
Off and on for the last few weeks the truck's had an intermittent weird surging feel, loss of power sometimes when driving then it quickly recovers. This only happens after the truck's been driven for a while, usually after twenty or thirty miles.
It's gotten worse. Runs fine when cold, runs fine on short trips, going to work is about a 40 minute trip, invariably, within five minutes of getting to work or getting home, the thing trips the CEL now, idle is very low, it stalled on me once, has the same bad loss of power intermittently. You can put it in neutral at a light, rev it up to 1,000 and it'll idle fine but CEL stays on. Get to work, park it, by lunch time, whatever's wrong has fixed itself - no CEL light comes on, truck runs fine. Truck runs fine getting me back and forth to lunch joint, ten minute round trip.
Going home, same issue, about five or ten minutes from the house, the CEL comes on, low idle, loss of power, etc. Let it sit for half an hour, the CEL will clear itself (honest) and truck will run fine. I'm in South Louisiana, there aren't a whole lot of auto parts stores on my route, and the two I do pass are in mid-route both ways, have had it checked there, but since no light is on, no codes are showing up. Is this a glitchy MAF sensor? It's making me nuts. I'm used to being able to drive this thing anywhere, and I've checked vacuum lines, and done everything else I can think of - problem seems oddly consistent whatever it is. Thanks guys, sorry for sounding dumb on this one.
