LeAccord

Hello, I drive a 94 accord ex. I put in a new k&n air filter today, just the cone no tubing. I already had a cheap air intake system in so I just left the old tubing in. My problem is that after the new cone filter my Engine stutters when I accelerate after about 3k rpm. It goes but then it stops then it goes etc. So I was wondering if it's because there's to much air going in now, or if anyone could give me any ideas.

sounds like a map sensor problem.

Thanks for the idea!

It's possible. Maybe the KN filter is flowing more air at that particular RPM that the ecu hasn't adapted it's long term fuel trims yet. I assume everything else is stock since you didn't mention anything else...

If it's adapting still, it should resolve itself after a little bit of driving. You can disconnect the battery and reset them also. Never heard of this problem before with just a filter swap. Let us know what you find! Good luck.
