Hi guys, my girl friends bother has a 2000 V6 Camaro with 86K miles.

His car is running like crap, I put my Predator on it and got P0300 mulitple miss fire.

We change the plugs with NGK TR-55 with factory gap (I think .055) and it ran a little better.

Then replaced the plug wire with stock AC Delco's and it's running better, but still not 100%

Also how do you guys reset the SES light, I can't do it with my Predator?

Thanks
Andrew

 

What do you gap TR-55 for a V-6? Is .055 to big?
