Tune up blues

duneyota · 11-06-2009, 10:59 PM

the truck was running fine,and then came the minor tune up consisting of new spark plugs,plug cables,and cap and rotter. Now shes is running a little hard with a minor studder only when cold.
i am thinking maybe a bad plug,but not sure where to start my trouble shooting.
thanks in advance...Rick

What type of plug did you use? From what i gather, the oem ngk or denso plugs are the best

did you double check the gap on the plugs before you put them in?

the first plugs i used were ngks unfortunately my gap was way off, recommended gap is 32..i had them at 38..lol.
so i bought a new set of plugs this time gaped correctly, the studder got better,but still not running how she use to.

any one think maybe a carb problem?

Could be a carb problem but I'd look other places first.

Fuel Filter?
Timing?
Air Cleaner?

Seems like your symptoms are related to the tune-up, but sometimes things just happen at convenient times
