New spark plugs and it misfires? No code HU?

New spark plugs and it misfires? No code HU?

So the car went in for its oil change at 26k miles, while it was there the tech decided to change the plugs.
OK

I get the car back and I just noticed that while it's idling it now has an erratic misfire?
And the only thing I hate more than fatkinis is erratic problems!

The car still pulls well and runs well and has not thrown a code but with this engine being as fragile as a fat chick rocking a micro mini on 8in heals....you never know when she will fall over in a big old pile of crap.

Good news is that I have a check up in about 1500 miles...no clue why but the car says I do. So maybe they will figure it out. Watch it's a bum spark plug or they forgot to add some dielectric grease to the spark plug nipple...he he he said nipple....before closing it all back up!

What do you guys think?

Probably one of the coils is not seated or the electrical plug is not fully on the coil pack.

Time to take it back...

Yeah but I can't freaking replicate the problem!
It's hit or miss. The car will sit and be just fine and then burble burble burlble....and then she is fine and again in 15 or so min burble burble burble!
I hate these kinds of problems!

So, they changed your plugs, and now you are having rough idle? Better get used to it.....Welcome to the club!

Yeah she is starting to sound like my freaking 1.8t VW!
But that car lasted me a good 120kmiles and was troubble free!

It might be the plugs...happend to me...bad plugs from Bav Auto. They were OEM BMW lugs but something happened to them...not sure what. Bav Auto is great and refunded me....don't think it was them, but the OEM plugs seem to be hit or miss....not that I would go with anything else anyway.

Yeah but how the hell am i going to prove this one?
Like i said it is hit or miss. So i can show up and say look....and nothing will happen?
Maybe shoot a video with the camera?
