Hi All,
I've been lurking for quite some time and posting where I could help. However, I've got a question regarding my 2000 SOHC.
I'm a little stumped........ In the first 15-20 minutes after startup, my truck appears to pre-detonate at 2k rpm - 3k rpm. It mainly does this at
1/4 to 1/2 throttle. I can let off or open the throttle to 3/4 or more and the noise disappears.The intake gasket and tensioner recall has been done so I think that should rule out noises caused by those components. Is this pre-detonation or something else?
Any ideas?
Thanks in advance for the help!
Scott
