Sometimes when I'm accelorating or holding a constant speed, my car shudders or shakes, kinda feels like a misfire. I'm right at 100k miles and I'm not sure when the plugs and wires were replaced, or if they were. We're changing them this week, but I was wondering if that is what is causing it. Does that sound like plugs? Or something else?

 

plugs and fuel filter would be a good start.

 

alright, that's what I was hopin to hear. I changed the fuel filter in december, so I hope this fixes it!

 

a plug not firing could cause a shudder, i'd loook there first

 

yeah, problem solved. replaced plugs and wires. :]
