My 97 Accord started to jerk when ever the rpm's go over about 3300 rpm's. I tuned it up Sunday, it ran fine before and after the tuneup. I decided to wash the engine compartment, after I got done I decided to go for a short ride and that is when the jerking started. It runs perfect so long as I don't go over 3300 rpm's. I have not had a chance to have it scanned for any codes since it is at the daughters place.

Without the codes, what do you guys think the issue could be?
