All,
I want to tune-up my 98 Jimmy myself. 75K miles. I've read everyones input on Delco vs Bosch plugs, buying a good cap, and buying good wires. I will of course try to buy the best out of all of the suggestions.
My question is that nobody has mentioned the timing. I know the timing light and manual adjustments are a thing of the past. Do I need to have a computer check and\or change my settings after a parts tune-up? If so I need suggestions. GMC wants $165 for plugs and I'm guessing timing.
Thanks in advance,
