Okay... here is my problem.
I replaced the timing belt and adjusted the valves. It took me 6 times to get the valves right, but i did it. Here is my problem:
I am having problems with pre-ignition. I tried adjusting my valves thinking that was the problem but realized (about attempt 3 or 4 on the valves) that the noise iheard was preignition. So a break out the handy dandy timing light to check things and my timing is off by only a degree or so. I adjust it, and my pre-ignition noise is even worse. The only way i can eliminate the noise is to retard the timing...right now, its about as retarded as droolin' Johnny riding the small bus. My problem is that i have an emissions test on saturday to make.
Anyone clue me in to this?
my first attempt at the timing belt change resulted in my timing being a tooth or two off (couldnt even find the marks to set ignition timing) so I set it back to the dealer specs (thanks again Paul) and now im having this preignition problem.
My distributor w/vaccume advance was changed about 10,000 miles ago.. is it possible that it could be defective? I have pinging with both the vaccume lines connected to the distributor and disconnected and plugged.
Im really stumped and im reluctant to screw with the timing belt again if i dont have to... thats why im asking first. I may rip off and exchange my distributor simply because it has a lifetime waranty and it'd eliminate one of my theorys.
Thanks in advance for any help.
