ignition? high rpm mis no CEL

[noid]

ok well problem is a misfire at high rpm when boosting (not at with free rev)no boost leaks.Good fuel pressure while misfireing. CHanged plugs tried to check ignition coil but my ohms meter is crap. noticed this coloring of 2 ignition plugs on coil pack. Is this normal? If not what could cause...this pics below.

^^^^^^^^^Click to see. The dark ones are a burnt bronze color and white looking ones are a very shiny silver color. Thank you fr any help you can give me.

it's tough to tell, but i don't think your answer is in looking at the color of the coil plugs.... looking at it's unlikely to tell, def. get your voltimeter working and do a resistance test on those secondaries....

are you pulling a misfire code? injectors could be another culprit....

THank you for responce. I'm not geting any codes at all.I said "misfire" because I know no other way to describe (bucking). I measured ohms today on ignition and Primary on cyl's 1&4 was 1.3. cyl's 2&3 was 1.2. I've read this is "out of range" with range being (0.70-0.86 ohms) My secondaries where 14.1 which is in range with range being(11.3k-15.3k). So does my primaries being out of range mean ignition coils are bad?

I've used injector cleaner twice ,but havent looked into them any further.I tried to get injector pulse on a universal OBD2 reader ,but was unable to get a reading. Reader did show that O2 signal cuts out while "bucking". O2 sensor signal tested and was working fine.
Thanks for any advice you can give me.

what you describe as "bucking" is typically a misfire....

, it's tough.... technically the answer is yes.... but i need to share with you a story....

a buddy of mine had an Olds Cutlass Ciera that would die out instead of go forward. i thought it was ignition related and tested the Ignition Control Module. it failed its resistance check so we paid $90 for another one... we put it in and it did nothing.

he finally got sick of it running bad and took it to a shop, and they replaced 4 of the 6 fuel injectors and its run great ever since.


slightly out of spec coil pack would only affect the vehicle when... well actually when you're describing... high boost + High RPM = demanding load on the coil...
