So sunday im running behind and work, and instead of going up the street and putting mixing 91/and 100 like i have been, i threw $20 in at my station and decided to fill up monday with with 100. Monday morning i have crazy misfrie/rpm issues when starting the car. I was going to log these issues but it seemed to dissapear lately. So monday i top off my tank which was alittle over a 1/4 of a tank full, withh 100octane. Long story short when i go to log the car this morning, no more issues. SO i know for a fact that i am running a 93 octane file. what file are others that use AWE code having this issue running. I personally have no probs, especially with the cost of 100octane vs 91, mixing every tank like i have been, but for some they might need to get a 91 octane program to fix this. This is all speculation at this point and i need to now log a tank of 91 vs 100 to see the diff but just wanted to see what everyone else thought?

I have a vacuum leak somewhere.. and when I reset the ECU its fine for a bit.. then as it adapts for the leak it starts to run like poop when cold.

I will be replacing the Spider hose tomorrow, as I have a cracked hose back there..

well see if that cleans it up..

my start the S4, and RPMs jump immediately and hop around for about 1 min, until the car settles down.

a few times it seems like the car was going to stall out too. odd, cause i havent seen this issue since going stage 3.

i dont like it either...

especially if it stops once the car warms up.

djillusion

yep completely stops when the car is warmed up..

Many will disagree saying you need a colder plug but you will only really see the effects of a colder plug after a hard track day. I have tried Platins and other cold plugs and have misfired badly on everything but stock PFR6Q's gapped to .28.

Of course, I can only speak from my own personal experiences while your car may act completely different.

these are the plugs that came with the kit

no its runs fine once it settles in not after you clear the codes. I have full boost

also...i think both codes are written for 91, as they dont have a specific 91 and 93. Though i hear most East coasters run the stock box file with 93+ and CAI open element file is rec for 91. *Shrugs*

btw...you have MAIL regarding AWE fueling
