has any one done an engine tuneup on their own. regardless of that which spark plugs and cables are recommended?

Use AC Delco parts.

are bosch parts bad?

Not, Bosch parts are good, for most stuff. Some people here have had bad experiences with their spark plugs, though. I'd stick with AC Delco.

ac delco is our oem right

right

I have good experiences with the AC-Delco rapidfires personaly.

The Bosch +4'* I was using worked great for the first year but detiorated rapidly after that. Not worth the almost 7 dollars US i paid for them.

I'll agree on the Bosch plugs. I've had nothing but trouble in any car with them. Don't waste your money on Splitfires, either. The NGK V-Max is a better, more reliable design, and costs less. If you don't stick with OEM, and wanna try something new, they're the plug to try.
