Yeah, replaced the timing belt when I did the water pump. Pinging before, pinging after.
Fuel filter? (origional)
vaccuum leak (intake, etc?)
plug wires? (origional from 1997)
carbon build up? (Seafoaming made white smoke only). Running up to 4 grand does not smoke.
What are the chances it's the knock sensors at this point? I mean, wouldn't that be slim, since I have no codes, and there are two of them?
I'm getting 21 mpg mixed city/hwy driving. Pinging is during acceleration, not loud knocks, definitely a pinging. Everything else ir good. This is driving me nuts...
