Plug Replacement 95 Aurora

Took my Aurora to have it checked out as it started missing and running rough. They checked it out and said the Plugs and wires were showing a lot of carbon tracking and needed to be replaced. They qouted me for Platinum plugs and hi performance wires and labor as $514.00 I thought this might be a little high. Is it that tough to change the plugs or can a home mechanic do the job. If so what is the easiest way to do the back 4 plugs? also the traction control has started to shut itself off not long after we start out. It seems to not do it as much when the engine is warm. Also it resets when you shut the engine off and restart. Thanks in advance for the help..

P.S. it has about 80,000 miles on it.

I would use AC Delco platinum plugs(factory spec'd for the car)and AC Delco wires(lifetime warranty). Wire set is around $100 and plugs around $50. Easy to do yourself. For the rear bank, unplug the coil pack wiring connectors then unbolt the coil pack bracket for access. Replace only one wire at a time to avoid cross connection. Spark plug socket, six inch extension and a flex-head ratchet and you're ready to go. Carefully check the plug electrode alignment and gap them at .050" for a '95. Apply a liberal amount of dielectric grease inside the plug boot before you pop them on and you should not have any more problems with tracking.

Thanks a bunch. Going to give it a shot tomorrow. I sure do miss the days of working on my 66 Impala or my 67 Firebird... Lots of room to work and not many hassles.

Thanks again

The manual recommends replacing plugs when the engine is cold. Got something to do with the aluminum block.

Correct! Easy to strip aluminum threads when hot.
