    Pending p0300. Misses going up hills

    I'm gonna try this post one more time with hopes a little more info will help.. The car has had a problem with missing going up hills since the pcv system went and was replaced. It bucks and the CEL flashes but will not set a permanent code. Currently the data I have pulled is
    cyl 1- 1 in last drive cycle
    Cyl 2- 197 in last
    Cyl 3- 2 in last
    Cyl 4- 228 in last
    And a pending P0300

    It will miss on occasion on flat ground mostly on hills pedal about half down and the car sitting around 3500 rpm. Not above 5000 and not below 3500. This issue is driving me nuts and I need some direction.

    Swap spark plugs 1 and 3 with 2 and 4 and see if your mis fires follow the spark plugs or not. If they do, replace your plugs, or , at the very least, re gap them. If the mis fires stay put, you may be looking at a coil pack.

    Agree sounds coil related. Did you remove the coil pack when working on the PCV system? I know with my old plug boots the spring would get caught up inside the rubber boot and i'd have to make sure it was popped down in order to touch the plug top.

    Regap at .028 and torque to 18ft-lbs - no anti-seize

    MSD Blaster OEM Replacement Coils 8236

    From Hesitation Gone:
    -BKR8EIX-2668 (iridium plugs), ~$25, expect ~10-15k regaps on these, ~40-50k overall life.
    -BKR7E-4644 (nickel/copper plugs), ~$8, expect 15-25K out of these plugs, with a regap or two required at 5-8k intervals on stock tune.

    What's the down side to anti-seize?

    To update last night I finally got a permanent code to set (this has been going on for months) I didn't have any tools to pull the plugs but I did pull the coil and check the springs cyl ?4? (one closest to air box) was a little out of place but "fixing" it didn't help the problem. I will be buying plugs and changing tonight to see what happens.
    Also dealer replaced the intake and cam cover. I've taken it back and they keep telling me nothing they will do without a check engine light. I already know it doesn't fall under power train (if it's a coil) but should I make an attempt to see if the dealer will fix? Or am I wasting my time?

    Would you recommend the MSD over a parts store coil or OEM GM? It is 50 bucks cheaper to get the MSD lol. Is there benefits over the stock coil? I've heard mixed reviews of MSD in the past but i guess if gm coil can't last more than 30k then who cares. Edit: nobody has the **** thing in stock kill me

    As Thebigzeus said, it will allow you to overtorque the plug.

    The suggested plugs have a special coating already part of it.

    I bought an NKG coil (new and stock) from someone on the forum just as an insurance policy. I found the MSD one after the fact. I have purchased other MSD products in the past and have had no issues with any of it. Look for reviews online to help you decide.
