- 2002 explorer
Ok....first let me say I am by no means an expert. Having a problem.
I have a noise, that I would describe as piston slap or spark knock. It only happens between 2400 and say 2800 RPM's and at idle speed in park.
I have switched to 93 octane, but it does not eliminate the noise.
I have used various additives that claim to quiet engine, valve and lifter noise, but they didnt work either.
Anybody know which way I should go here?
The dealer told me this is normal for an explorer with 85k on it.....I dont buy that!
