I have been getting the hesitation problem that quite a few people have been having.. surging at idle and bogs down under gas then takes off when its been running at operating temps for a while.. it runs likea beast when its cold.. but once ive been running it for a while its really annoying.. anyways ive been thinking about getting new wires sense it seems that the wire changes helped alot of people and that the 7 wire is getting too hot/burnt.. well I was looking at wire kits and I found a taylor thundervolt one that costs $120 but can withstand temps up to 600 F or something like that.. seems to be real top of the line.. i was wondering if everyone thinks it would be worth it? Can I just bring the wire kit to the mechanic and hell put those in? I dont' know how to work on cars.. and im really getting annoyed with this hesitation problem ive had it for about 2 years now..
