Anyone know why the timing would change? Is that just wear & tear on the timing parts?
Coupla questions on the O2 sensor and timing.Bob Lincoln said:Either one.
A bad O2 sensor can cut your mileage in half, if it's really bad.
The carb has electronic controls on it - ie: a feedback carb and the O2 sensor can adjust the air/duel mixture. I'm sure it can't adjust in as wide a range as fuel injection but the carb can adjust somewhat.On the carbureted V6, how does the ECM control mixture? I thought the only thing it could adjust was the timing.
No, I didn't have the $$ till today. Looks like they had 31k miles on them. I'll try to post a pic of them tomorrow.Bob Lincoln said:How many miles were on the plugs? I thought you had replaced them.
31K is awful soon for plugs to look that bad, but it could be a combination of it being out of tune and the "wrong" plugs in it. I've had Bosch Platinum plugs look like crap after 10k miles but most others have lasted far longer.No, I didn't have the $$ till today. Looks like they had 31k miles on them.

I did not know that. I'll swap out the cap as soon as possible. Thanks Bob.Bob Lincoln said:It's vital on this engine and the 318 to use a cap that has brass inserts and not aluminum. That white residue is aluminum oxide and forms quickly, and causes misfires and reduced spark.
