    Again with the misfire!

    Hi all!
    I’ve had some misfires again! I had the chain phasers and supposedly the vct solenoids replaced. But I’m getting a misfire again very intermittently. It’s a misfire for all cylinders, it also comes with a p054a. The misfire only happens under heavy acceleration above 55 mph and is very violent but it’s rare.

    Any help??? Please???

    Do you have the hole drilled in your intercooler? If not, do a seach on the forums and drill the hole.

    I drilled the hole. After test driving, dirty water everywhere!!! I will also be changing the spark plugs as a precaution. Hope this was the fix!!!
    Thank you!!!

    Leave the hole open. As moisture accumulates it will weep out the hole. The loss of boost at low RPMs with the weep hole has been shown to be negligible to the overall system. Plugs should be gapped at 0.028-0.030 if running stock. Since you had misfires on the current plugs, be sure to check them carefully for cracked insulators if you're reusing them. It will look like a hairline crack in the porcelain. Replace them if you see this.

    Well I drilled the hole earlier in the day, drove for 15-20 minutes got home and noticed oily water underneath. I just drove to work 45 minutes and it misfired under a load condition three times, It may still have some moisture in it I don't know. I will be changing the plugs and boots soon.

    What do those codes come up as ? Could still have a bunch of crap in the intercooler still if misfire. Try pulling the cold side AT intercooler (one spring clip) and putting a towel in there see if it soaks up anything.

    If you are misfiring under load, try this, instead of going on a road in 6th gear like 45mph, do it in 2nd and let the rpm hang up high, get the engine nice and hot this way. It wont have as much load on it in a lower gear like that.
