As soon as I fix one problem another one arises. I was throwing an egr code that was as simple as a line that had come off. Fixed that.

Then it was a p0300 random multiple cylinder misfire. I thought maybe the plugs got fouled from running too rich with the egr problem. Changed the plugs last night and seemed to run fine.

I now have a studder under heavy acceleration. I'm running outta ideas on how to fix this thing.

 

You gap the plugs? Your MAF ok? Did you check for boost leaks?

 

I gapped the plugs to .24. I have no idea even how to know if it's the MAF. I haven't done a boost leak check. Not real sure how to.

 

Check the gap on your plugs since you just replaced them...I had the same issue and the gap was the culprit for my wot studder.

 

It feel like it's just randomly missing at idle too.

 

Yah recheck the plugs but if you can find anyone to do a boost leak test for you would be helpful. Pretty easy to do if you can find someone that can blow smoke through the system that is the best way I found to search for leaks.

I don't gap my plugs. I thought the iridium plugs come gapped so I don't mess with them.

 

make sure you used the right set of plugs, and maybe a tune????
i had the same problem but it was just a gapping problem and everything was fine after that

 

Pull the MAF sensor connector.

 

Make sure there is no kind of vibration in your clutch assembly or tranny. The knock sensor is very sensitive and will cause a misfire every now and then. I had that problem.But make sure plugs and gaps are right first.
