Mercedes-Benz 1998 E320 - 160,000 Miles Strong
I did a spark plug change on my friends AMG 1997 E420. Later during the week he noticed that the power was erratic after he put his foot on the gas sometimes. I tested it out and it happened to me on the freeway going about 70ish I put my foot on the accelerator then released my foot and then I press on the gas again and 0 acceleration for about 2-3 seconds after that I get TOO much power I have to let off the gas. It has also happend at stop lights. I'm waiting at a RED light, GREEN, I press the gas and nothing,2-3 seconds later I'm over reving. I dont know if the spark plugs job has anything to do with this problem but it seems to be getting worse. Any ideas??
