Hi,
I have a 4 bolt 350 in a 88 burb, rebuilt with 70,000 + km on it. I will be driving, or just starting, the engine will run rough and the engine light will come on. The engine misses. If I turn the engine off, let it sit a couple of seconds and turn it back on it's fine. What gives here? Also sometimes it will cut out for a second or two, then cut back in and all is well. I can't seem to reproduce the problem, for example I thought it might be a lose wire, so thought perhaps going around a corner or something, but nothing seems to trigger it, it's just random.
Any thoughts,
Clint
