Check the timing if you can and set it to 10*BTDC (make sure you follow the correct procedure to set the timing...).yeah its a pinging noise
It should be in any manual. If you don't have a manual for your car, I suggest you go over to the Camry forum on AutomotiveForums.com and download the appropriate manual for your car. The manuals for generation 2-6 are stickied at the top of that forum and are available for free downloading.is there a how to to set timing?
Wait, do you actually put load on your motor at 1500rpm? Manual or auto?ok so i up'ed my grade to 90 noticed a little difference the rattling stoped at about 1500 rpms ten last night i put some seafoam in it to clean the crap out of it and we'll see how it goes from there
