I really appreciate everyone's help.
I'm just looking to possibly get my engine running a little smoother. There is a slight knocking or tapping, which I understand could be valve clearance. Also, it seems like it could be missing at vary low idle speeds, which would be timing.
Basically do a tune-up, w/o taking it to the dealer. If there's anything else I should be looking at/checking, or could do to get it running smoother, don't hesitate to suggest.
If I buy a shop manual, is this going to explain how to do these two adjustments (or check them), or am I just using the manual for the specs to check? Because if it's just the specs I'll find them somewhere else. Also, I'm thinking if I'm going to be doing any engine work at all a manual wouldn't hurt, so what is the best brand? Is there a decided best, or does everyone have their own opinion?
Thanks again guys.
