perhaps your riding the gas peddle more? have you been doing more city/stop & go driving lately?
add some Seafoam to your gas tank. 1 full bottle right before you fill up. might do some justice on those high mileage injectors.
I just picked up some plugs, cap & rotor. 4 day weekend, time for a tune up, suspension check & clean, wash & some engine bay detailing
I have Jay's grounding kit to install, and his red spark plug wires. just need a red filter to finish it off.
