After i took my 96 GTI off a 3 foot wave it began to run horribly. If you punch full throttle at a dead stop you hear the engine revving(slightly higher pitched revving then normal) but there is little to no propulsion. If you let off a little, it will pick up and go and you can "baby" it into full throttle after a few seconds of 1/2 throttle but why would does it not propel correctly from a dead stop. Sometimes it runs well when you get it into full throttle but other times it temporarily bogs down and then picks up. I replaced the spark plugs last week but i noticed they were kinda dirty after 1 use. Could it possibly be the wear ring?
