Dave,
that car has 43,000 miles.
A bad plug or plug wire can be confirmed with a screw driver by shorting out the plug and then swapping it with an adjacent cylinder. Takes about 10 minutes or less.

Don, I hear your pain and it reflects mine.
every time I take one of my cars in for service they stongly reccomend about 2500.00 worth of BS preventative maintainence they call it like change all the hoses, changes all the belts, change all the brake oil, etc. I had the dealer appraise this car while there and they said low of 2500. This is a car that cost me over 20,000 6 years ago. Some how all these numbers don't computer

Mike,
Saturn Corp. sez there are no open recalls or campaigns on this vehicle number's VIN.

Charley,
It is about a half hour job to swap a set of 4 plugs in this engine. Remove a plate on top and there are the sparkplugs and wires. My neighbor replaced both plugs and wires for parts of 80.00 and his labor of an hour.

I have received a lot of replies from the Motorhome tow car forum as this saturn is the toad that is towed by my motorhome and we have special forums at IRV.COM for anything and everything about motorhomes and the toads that are towed.
I had a reply from a GM Technician that stated the charges seemed way high to him based on the amount of time it takes to do that work.
Another wrote me that when he complained about the price gouging at a California Dealer to the Saturn 800 number, they sent him a $100.00 Chit to be used at any Saturn dealer anywhere. This sez to me they are agreeing that Calif Dealers are gouging their customers.
