i am pretty sure my computer is gone bad please tell me what you think. first my plactic intake cracked and was leaking coolant onto cyl#5 so i causing a missfire. so i did the intake cleaned the coil and plug now my i am getting a missfire on cyl #4 immediately after installing the intake. i have changed the coil and plugs and still a missfire, i also tested the injector and did a compression test and all is fine. it seems to be an intermittent missfire also. it is worse after driving for a bit and when i stop only after driving it for a few the idle surges. oh and i also got a code p1000 saying that obdII tests incomplete. anyone have any ideas???
