so i picked up a 99 2.5rs last week, the guy told me he put new pluggs, coil, fuel pump and fuel filter on it, and a aic sensor, he said it wasnt starting! so two days later i drive it up snowboard( ripped a few doughnuts and drove up the pass in rally mode) park it and try to start it to warm my gloves! wouldnt start, come back 2 hrs later wouldnt start! go to pop start it and it fire on the last try befor pop starting it! drive it to a buddys to go over it everything seems fine! found a lose air intake tighten that think it fixxed!later that night it wouldnt start, wouldnt pop start, finally a friend tapps the new aic sensor while turning over and it fires! for the next few days it would not start like once a day and i would have some one tap it and it would fire! now it wont start at all! i pulled the aic it has no real carbon on it! so i pulled it out and the piston moves in and out when u turn the igition on and off! im so comfused! any ideas, the car it turning over great and has fuel to the engine!
