I have spent all night reading past posts about bucking in our cars. Mine has been getting worse. I replaced the +4's 3 months ago with Autolite Single Platinums that NAPA told me was a direct OEM replacement. Are these bad plugs to use? This bucking is getting worse. I have FMS wires that I have had for about 50k. I am getting ready for a 1300 mile trip in 2 days. Should I juts go buy Bosch Wires to have something new in there?
Any help would be great.
Thanks
