do the complete tune-up and get that out of the way. Flush the coolant, change the oil and oil filter, change the plugs, wires, air filter, fuel filter, fill the tank with 93, check all you fluid levels, including washer fluid, brake fluid, coolant, and make sure the brake lines are in good shape.
As per the oil, everyone has mixed feelings. I am told that the pure one filter from purolator, and mobile 1 synthetic 5w30 was the best blend, but everyone has a differing opinion on their oils.
Prestone 50/50 coolant is fine for the rad
and regular sae brake fluid to top off the unit.
High octane only from here on out.
Plugs should be the champion AC's....I forget the number's off the top of my head. 230 sumthin I think.....But I forget.
Wires.... Magna cores found at Kenne bell or Summit, should be 8.5 or bigger in the mm's. Poston sells performance wires for a good price too.
The coil pack should be checked out, possibly upgraded, but for now, if the car is running well, I would leave it alone. Lets get this started the right way, and get you on the road to 13's!!
