Current tires are all seasons, UTQG = 500. Not great, but good for listening/feeling what over-driving is. I have a set of 17's that I'm going to throw summers on once I freshen them up.
I haven't been out in about 2 months trying to tackle this misfire issue. Hopefully this summer I'll be back at it. The Firehawks are on my list. Everyone says their great for the price. Your tips have definitely helped. I feel like I jumped in trying to be Randy Pobst from the start, and that's more detrimental than anything. Ever since then, I've been listening to the car, feeling it a bit more, paying attention to the nuances. I need to put in some work!
But thank you again, it is much appreciated!
