While running at any speed from 800-1200 rpm the car surges or spudders. The rpm doesn't jump around at all. Also, this doesn't happen while in park or idling in drive while stopped. thanks for any input in advance.
bought it a month ago, changed the cap/rotor, plugs and wires. it was doing it a little before I had it tuned but now I'm noticing it more. I'm taking it back to the shop that tuned it next week but I was just checking for ideas. thanks
