Message	fine when I left home. Got to work and it was idling rough and afr was hovering around 16-17:1 And again, on my way to work I got on it in third gear and had major hesitation in the 5-7k rpm range. Max boost was around 12psi and it was still cool out when I left for work. Wonder if my fuel pump is failing. Guess I will have to install a fuel pressure sensor and start data logging.

Seems like heat range 7 is what SZ is recommending - MixManMash 21:12:56 07/10/12 But does it make sense that I would need to switch plugs - Evan_Wright (Ca) 21:48:08 07/10/12 It could be possible. If you have a log of before the gear - MixManMash 08:17:19 07/11/12 Interesting update. Drove it to work today and it idle'd - Evan_Wright (Ca) 12:57:42 07/11/12 strongly suggest that, my gauge has saved me multiple times (n/m) - Red Hawk (CO) 16:12:36 07/11/12 Re: Main causes of missing under high load? - unfamous 23:48:00 07/11/12 Thanks for the suggestions.
