Is this be something I should worry about?

Hevath · 07-03-2010, 09:05 PM

I was on the highway and I just got on the gas in 6th gear and it started to sputter then the engine light came on. Was very rough driving in limp mode. Turned the car off and back on... and its as if nothing happend. WOT is fine now and everything seems ok. Is this be something I should worry about?

I have a regular JB2
HKS BOV (I know .. i know... i just love the sound)
and AFE intake

No major mods and its been a month since the mods were installed.

I reset the engine code (Misfire on Cylinder 5) all seems ok so far

thanks in advance!

yeah it doesnt seem as smooth anymore, small sputters seem to be happening at WOT. but has yet to trip a code is there a test for bad coils or plugs? searching threads after this post for an answer

I also read that the front O2 can cause misfire on 4 5 and 6 but I havn't installed DP's or touched the sensor that I know of. Could it be the JB2? Its been working great for over a month so not sure if it can cause this. Thanks again!
