Not sure if your referring to my situation or not but my factory plug lost a ceramic. I then switched to NGK and gapped them to .028 without messing them up bit I was having those misfire issues 4k rpm and up full throttle. Got a second pair and same issue. Got Denso today and just dropped them straight in and bam I've had no issues all day and I've had a good amount of full throttle today

Appreciate your full accounting of the obvious ...
Juben called this 1 .. I guess I will be checking into the Denso ITV22 to see if the pop I am hearing goes away ..

He was right about it being plugs bit mentioned the insulator. Mine were all fine in those way. Club America actually said it about switching to denso. Obviously

 

[Blyman93]

Bad news. Problem came back

Is your meth kit on? If so, try turning it off and switching to a 91/93 only tune and making some pulls without meth.

Meth wasn't on. weirdly went all day no issues. Only a last run to the store did some 3rd and 4th pulls and it's missing.

The next time you're going to be driving it and getting it close to the rpm zone where this happens, try to get a log and let's see if we can tell anything from that.

 

[Blyman93]

Will do. Not sure exactly how to upload that to here however

 

[Juben]

You can upload it to datazap. That's an excellent program for reviewing logs and I use it exclusively.

OMG, ty Juben - thank you for sharing Datazap. I have actually been looking for one, was actually starting to think about writing my own.. Oh well saved my a fair few hours work there

 

[Blyman93]

Ok. Still in CA so will be a bit till then. However have driven 800 miles since I noted the issue was back, that was only present that night for some reason. I've had numerous 3rd and 4th pulls one to 140 and am currently not having an issue. This is inconsistent AF.

Here's a question, my knowledge of things is limited so if this is stupid disregard. I drained my battery a month ago accidentally. Had to get jumped and everything, could that have an effect on the power going to the pump or the coils? Btw issue still definitely present.

Wouldn't think so. Datalog is still the way to go. Would be pretty rare for the FP to be failing as it would be leaning out all cylinders I would expect.

Clean the connectors for the coil packs and visually inspect the wiring to them the best you can. Next step swap out the coil packs with other member/friend and if that is the fault swap out one at a time until you find the unserviceable one.

Problem is I have used another members coils lol he doesn't have issues yet I still got sputtering with his. So I don't believe the plugs or coils to be it. But I could very well be wrong
