Experts, I just drove my MY 01 996 C2 27k miles odometer, from the airport, and it has a violent vibration at low speeds under 20mph and under 3k rpm. I don't have a CEL reader to post the codes When I was not on the gas the vibration went away, put as soon as gas pressed it came back. Pulling off and under 20 mph it felt like the something drastic was about to happen and the CEL was flashing. Btwn 3-4k rpm it was less violent vibration but still bad. I recently got it back from the shop and but it was only for oil change, and brake flush no engine work. The MAF sensor was already replaced last yr, maybe 4k miles on that. I searched the other threads and it could point to ignition coil pack. I drove it about 14 miles and tried to baby it as best I could. The dealer is about 20 miles away mostly highway, what are your thoughts on driving it to the dealer, or should I tow it. One post said u could damage the cats and there really expensive. Can someone give me guidance if it is ignition coil how big and costly a job that is? I know u don't have much to go on w/out the codes. Question - should I err on the side of caution? Thanls in advance for any guidance, and i'll update the outcome
