Ok so here goes the novel.. I got a 03ba xr6t. It's a 5 speed manual. Say when I'm driving along, I come to pull up to set of lights or stop sign, il slip the gear into neutral, THENN my idle without me doin anything, rev itself out to about 2 grand, the engin light comes on and the the whole motor gets thrown into a misfire.. The other problem is my computer is t relaying the message of what's wrong..'iv had the car on the dyno and it showed no problems.'did a vac leak test and compression test and all is ok.. I can't figure out the problem and it's killing me!! Also my fuel consumption is crap too at 19.1L per 100.... To add, I had my throttle body changed to brand new initially cause of this.. Please!! Any information on solutions to this!! Thanks
