Question Question about an ECM problem?

I just took my MY02 WRX in on warrenty now here is the problem. The dealer told me that the #3 cylinder was misfiring because there was not enough fuel burning off due to poor oxygen consumption. The dealer sent in the ECM to get it remaped so there would be a widerwindow for the spark plugs to fire. He said the problem was due to the fuel I was using. I live at high altitude in Denver CO and he said that Federal Law requires the fuel have a higher alcohole content for enviromental purposes than in Japan and OZ.

Have you heard anything about this Federal law?

I was using Premium UnL should I continue to use Premium or go to a lower grade? (I think I should the higher grade for the Turbo)

I was also wondering if I should use Synthetic oil or continue to use the 5-w30 SEA?

Is there any brands of gas sold like Conoco that I should avoid besides generic?

Confused and need some answers!!!

Thankx
Erik

Sounds a bit fishy to me, but I don't live in colorado...Try asking the guys in the Rocky Mountain club forum. Otherwise I'd say buy premium name brand (Chevron, 76, etc.) gas. If that still doesn't fix your problem, I'd say you have a ECU lemon! (so to speak)

I picked up my car Thursday and it seems to be running well, but I really haven't driven it all weekend because I went to the Olympics. I'll be asking a lot more questions if it happens again.

I would also like to know if I should use synthetic oil or just stick with the 15w-30 SEA?

Thankx
Erik
