Ya I don't have my wide band connected to the pcm. I did get an o2 slow response code but am nervous about spending 60$ on something that I really don't think will fix the problem. The o2 data is only used in closed loop which is basically normal cruising around town or at idle after your warmed up. My problem is at idle before and after warmed up but I have zero problems and zero misfires cruising around and then at wot when the o2 sensor data is once again not being used I have issues. So Idk man I'm going insane. I think its fueling but if it was fueling why would it happen at idle with such a low load on the engine but then be fine cruising around town at basically anything under 40% throttle. It just doesn't make sense. Hppefully my dad can come over tomorow with his fuel pressure tester and compression tester. I'm just really hopeful its not a chipped piston or something but when I pulled the spark plugs they all looked perfect. No build up or deposits on them. Basically brand new with a hint of burn on them. Ive had the car over 2 years and never replaced the crankshaft or camshaft position sensor I know normally the car just won't start if one is bad but I'm wondering if I have one that is just half dead or something.Originally Posted by w3tbanana
