Don is good people. He will hook you up.

Replaced Fuel Filter Yesterday... I coughed up $50 to have Tires Plus in Cherry Valley do it...

It seems to have fixed the intermittent stalling and running rough... It's like nothing was wrong except for the fact that when I am on I90, the SES light flashes... no misfiring... it's weird... I'm going to get with TheAutoGuy to use his garage to pull the plugs and regap them to .060 to see if it is that.

Flashing SES means constant misfire.... and if it was Cyl 1 and 4, don't those share a Coil?... also, for $250, you can replace the plugs, wires, MAf, and ICM. Why spend that at teh stealership?

So it's a possibility that I am looking at a bad coilpack too, amirite?

Wires and plugs I should be good on, once I regap... wires checked out too...

If I am going to replace MAF, should I just pop off the money for a N* TB and the necessary related goodies?

Unless you have a ported blower and smaller pulley the N* wont net you much power gain but will give you a slightly quicker throttle response and will need a tune. Clean your MAF with a q-tip and rubbing alcohol.
Take some sand paper on the coil pack ends and make sure the ICM is tight before you go swapping them out. Make sure you use some DE grease on the wires.

Not too, a bad coil pack will cause issues like this

 

[RebelGTP]

DE Grease has been used on the wire connections to the plugs, I will go get more to work the coilpacks tomorrow.

I'll have to pick up that MAF bit to pull that out, I planned on doing it long ago, but never got to it...

I just had a similar problem. Car would just start screwing up, and it would stay running but would barely move and if you tried to give it throttle it got worse. Turn off the car, and it would start right up, and run fine like nothing happened. Seemed to happen more when the fuel was below 1/4 tank, so I assumed the pump was giving me trouble.

Ended up being the fuel filter. It fell apart internally, and the metal center that held the pleats would block the outlet limiting fuel supply. It literally rattled when I removed it. Might be worth checking out.

Wasn't even that old of a filter, maybe 6 months on it.

Did that two days ago... and I think it was the original 8-year-old one on the car...

it's running really decent now

 

[Ron Vogel]

Yeah, I read the original post, and didn't read the others...I see now you already tried that.

Even on a stock L67 I'd never run a .060 gap though. Maximum should be about .056-.058

Advice noted... It's on a .065 gap now

Though, my fuel mileage is ramping up significantly as noted by the DIC...

Just also want to thank everyone who has chimed in on this thread, the advice and help is greatly appreciated. It's also good to know that there is a good amount of previous experience and knowledge that can be tapped. Thanks guys!

Cleaning the coil packs is a good call, that reminds me I had a problem with them having bad connections. Easy fix to taken them apart and clean up the connections.
