Last year soon after I bought this truck I ran into this problem that seemed have been solved by replacing the starter.
Several months later the problem returned, and cleaning the MAF sensor seemed to do the trick.
About a month after that the problem came back and replacing the MAF sensor solved the problem, I thought.
Last week the battery died. Died as in suddenly quit acting like a battery. I replaced it and the problem seemed to go away, for about a week.
The symptoms, which are intermittent, are:
1. Misses when driving, but can drive fine for hours without missing.
2. Difficult starting. During cranking the engine will buck, or stop, for a moment, then continue, as if the timing was way off. When I stop cranking the engine sounds like it turns a little more, firing twice, weakly. Also, I smell gas.
Odd symptoms, for sure, but maybe folks familiar with Chevy V8s will be familiar with it.
I'm guessing another sensor, possibly the crank position sensor, or a vacuum leak. Someone suggested the ECU may be failing. I don't work on newer cars much, so... ask me about 1969-73 Opels and I can help.
It threw a code the last time I drove it but my reader needs my laptop and the laptop is now on the charger. I should have the code within an hour or so.
