The guy I have tuning it ran the exact check of the plugs you mentioned.. He said I was good to go.. It runs very strong. With no smoke and no rough idle. the car originally came from Las Vegas. I have all the records.
I do have a few parts to replace. Front driver side rotor(warped) and a tail light bulb. not bad for a car that sat for 4 years.
Im in Hobart.
