Houston, we have a major problem.
Up until two weeks ago, my old RamCharger's been running like a champ. And then all Heck broke loose. I went to start it one morning and she fired up like normal then quickly coughed, sputtered, and died. An attempted to restart got good cranking, but no fire and a smell of raw gas. So I wanted a few minutes for it to clear out, and then tried my fathers old trick of starting a flooded engine. I put the peddle to the floor and tried cranking again. This time it caught but ran extremely rough and if I even thought about taking my foot off the floor it would start to die. I also noticed a bit of black smoke coming out of the tail pipe. After roughly 15 to 20 seconds the old 318 sprang back to life like nothing was ever wrong. It's now done this on 7 other occasions. Each time it would not fire unless the peddle was on the floor or I left it alone for a few hours. Each time once it worked through what ever it was choking on it's run absolutely fine.
The truck's an 88 with the first year for the tbi. 4x4 and the good old 727. I've checked timing, plugs, wires, filters, been through the wiring harness. I'm hoping someone here's got an idea of what may be wrong. I've taken to driving the old '84 while I sort this out but it's got a bad steering box and quite frankly scares the crap outa me.
