I'm puzzled. :screwy:
I have a 2000 Plymouth Grand Voyager with 90K on the 3.0 liter engine.
It started running rough and missing, so I took it to my mechanic. We did a tune up, but that didn't help. He found a leak in the intake manifold, and we fixed that. Still nothing. Code said it was missing on cylinder 2, so we replaced the injector.
The thing still runs like garbage.
Someone mentioned it might be a bad EGR valve, but nothing comes up in the codes. My mechanic says we need to replace all of the injectors, but I have reservations that such a specific problem would be caused by bad injectors. At low speeds (under 40) and high speeds (over 55), and when I'm in passing gear through 40-55 it runs better. Not purring, but not nearly as bad as when I give it normal acceleration between 40 and 55.
Anyone out there have any idea what could be the problem?

Just to clarify, did the mechanic clear the code after replacing the injector, and it came back? Not sure I would've replaced the injector right up. Unless I had a spare one on hand, I'd have put the "bad" injector in a different cylinder and seen if the problem moved to that cylinder.
You mention at low speeds and high speeds, but I'm wondering if it has to with engine idle. The IAC valve routinely causes poor idle quality if it gets gummed up, but that should subside when you open up the throttle.

He did not clear the codes. We forgot to do that, and the next day I left for a trip. The light is still on, so I guess we need to check that.
Changing the injectors requires taking the plennum off, so it's not so easy to switch and test, as the whole thing has to be put back together.
I'm hoping when we read the code it will tell us something new.:smooch:

Welcome to the forum. There are many possibilities. Read through this:http://www.obd-codes.com/trouble_codes/generic/p0302-cylinder-2-misfire-detected.php
Next time you post please type in a subject that discribes the problem. "Help!" doesn't do anybody any good when they are searching through the forum for a post regarding the problem they have.

Sorry. I fixed it.
I'm new here, and just learning the ropes!
