Help!!!

I have a 94 Accord EX with 253,000 miles. I got it at a great price and I have had her a few weeks now. I have run into a lil problem though. She started stuttering(no loss in rpm's though) between 3-4000 rpm's while in park revin the engine. On the road she will do it at about the same rpm's but when I give her a lil gas she will smooth out. I replaced the plugs,wires,dist cap and rotar button but still doing the same thing. I took it to my mechanic and he really did not know...He said it was happening on the third cylinder???

He said it may be an injector??

Has anyone run into this problem?

What do you all think it might be?

maybe ur injector ur injector is prob clogged or havin probs of some sort for ur 3rd cyl, could be the reason why ur problems are within only a certain rpm range and when u hit the gas u smooth out cuz ur usin more, u feel me

Everytime you step on your gas pedal, the fuel pressure goes up, that's probably why it smoothed out.. assuming injector is the culprit here..

Just get the injector cleaned, use one of those injector cleaner.. or get a new set..
