Hi - I have a totally stock 81 with a 350 and an auto trans. One day, it started backfiring through the carb. Usually I would be inclined to think something like that would be timing related, but the timing on the 81 is all electronic through the computer. I've verified that all the spark plug wires are in the right spot. I've checked for vaccum leaks and found that the ported vaccum sensors out of the thermostat housing were both broken. I replaced them both, but that didn't fix anything. Any suggestions?
Thanks!
Thanks!
