Started noticing a slight miss around 4-5k when at WOT and figured id start down the list and at the top is spark plugs. Now I don't know a thing about the whole 1 step 2 step colder stuff so if someone could enlighten me and give a recommendation base on my mods. Thanks!

 

What are ur mods, i know u was running a suoer aggressive lulley at one point without meth or e85. Have u pulled ur plugs and checked them? What plugs are u currently running we need more info to help ya.

 

Does it feel like one time one and always at the same rpm? Mine occasionally has a miss/studder at the same rpm every once in a while since 2005 and 80000 miles. Another local had the same problem too until his car was totaled. It has done it stock, stage 2, modified stage 2 tune, and e47. All of them were new tune that were loaded on then tweaked. My ecu was even changed trying to diagnosis another problem.

Car still runs great so I never really worried about it.

 

Iv had an issue before simmer to what u saying its happen maybe 3 times total since iv owned my car and on stock n tuned, it felt like a miss around 6k+ range. But like I said its only happened like 3 times someone told me it may be the car pulling timing due to knock.

 

No I haven't pulled the plugs yet thats my plan today lol I got home too late to do it yesterday and I won't know what I'm running till I pull them...the glories of buying used ...and I haven't paid attention to if it happens at the same RPM or not I just notice it everynow and then. the pulling timing thing would make since in my case. and sorry forgot to mentions Mods are in sig. (ZZP 2.6, 60's, ZZP Tranny and Motor Mounts, Injen Intake, Full Catless Exhaust, CX Racing H/E,Upgraded GM Clutch,Old Rakes Tune)

 

Just an update, Changed plugs (looked very worn), put in NGK Iridiums gapped at .035 runs like a champ, Acceleration smoothed out and no up top missing =D

 

Nice u still need to get ur tune and pulley fixed lol ur running wayyyy to small of a pulley to not have meth or e85

 

Hasn't done it for a couple months but was always at the same rpm and the hpt log didn't show any knock. Although I don't do ,any multi-gear pulls much anymore. It happened at the same rpm as another local years ago. I am on e47 now so it is very had for me to get knock.

I would just say it is an electrical/ecu glitch.

 

yeah yeah yeah, im living life (or my motors life) on the edge

Talk to James and said he wouldn't be free to do any tuning for a while so can't do much till then
