So my hardbody has developed an idle problem. At idle it's stumbling around and missing. It's okay driving, but at stop signs/lights, it's got the rough idle and shakes around pretty good. Kind of sounds like a popcorn maker.

I cleaned and reoiled the air filter, and also put another MAFS on. The sensor wires themselves looked fairly clean when I inspected them, so I left them alone. After that was back together, started it up, but same results.

There's brand new NGK plugs+ wires on it and I just read the codes.

Just making sure:

5 red flashes
5 green flashes

Means code 55? If so, then that is the "No malfunction" code.

Any ideas?

More than likely a vacuum leak somewhere.

That, or:

- EGR valve sticking
- bad injector (doubtful)
- bad plug or wire
- low fuel pressure
- bad O2 sensor
- clogged IACV

I would pull the plugs and look for one that's dirtier than the others. You might have a bad plug or wire, even though they are new. It happens.

How's the cap and rotor?

Hmmm, looks like I have some detective work to do.

Here's a quick vid I shot with my cellphone (which I love BTW)

PS, the dog is a camera nut... whenever he see's one he goes bananas!

Did you swap out your cams? Sounds good.

Based on that video, I'm leaning away from plugs and wires.

I just watched it again...mine did the same thing when the MAF plug got screwed up. Wiggle it around when the engine is running and see if anything changes. It's a common problem. Mine was even "fixed" at the dealer before I owned it, but failed again a few years later.

Haha, I know! It does sound like its cammed. I'll try the MAF plug and see if it changes.

K4AL called it.

Was a vacuum leak. One of the hoses going into the charcoal canister somehow wiggled off the canister. As soon as I plugged the hose with my thumb, it purred like a kitten.

Kind of mixed feelings, glad it's fixed, but also feeling like a dumbaxe since it was pretty obvious!

Thanks boys.

Better than running crazy lean.
