I had my car tuned yesterday and they found a minor misfire on the 2,4,6 side of the motor, its all cylinders.

Not bad enough to set a light or cause a noticeable drop in performance but its there.

Tech suggested O2. He checked for leaks, DV's, etc and they all came back perfect. New turbo's, new EGT's, everything else checked out.

I do get what I feel is a hesitation of sorts in 6th gear accelerating from 70 and up.

Car acclerates fine and I think the feeling is from a mount issue but it could be the motor.

Engine was recently(less than 2K miles) removed for turbo replacement. It was leaked down and checked over so no problems there.

Before I pony up for new O2's I'd like to see if there are any other things to check.

They did check the ignition amplifiers and those were good. Doubt 3 coil packs went back all on one side.

Thanks!

I had my AR chiped last weekend and lost three coil packs withen 20 miles. I lost 2,5 and 6 it could be luck or in your case bad luck that you lost all three on one side.

good luck

Swap the misfiring cyliders coils with the other coils and see if the misfires follow the coils. An O2 sensor will not cause misfires.
