My 02 gt 5spd is lacking power through the rpm range. First off I bought this 3 months ago and is very good shape and maintained. First test drive, she would slide in third. Now it won't hardly spin in first, it does still through u into the seat, it just wont break loose. I will floor it in 2nd from 3 grand and it Just dont respond like a feakin gt should. It seems like it gradually got this way, and also it has offroad x with 1 of the o2s not working at all. But it was like this when I bought it so that don't make since. Also has new fuel filter. What should I do or Check? Also it tries to squall tires more easily when it's cold, but is back to the bog in prolly 30 seconds. Please help cuz it's pretty bad when a gt can't smoke a civic
