I've got a bit of a problem that is more of an annoyance.
S52 with OBD2 and M50 manifold. It bucks HARD at low rpm/low throttle crawling. Basically any time I'm cruising in stop and go traffic it'll at random cut all throttle for 1/4-1/2 second then kick back in. It happens frequently, and I drive in stop and go traffic frequently. I do have a decent diag suite, but not sure how to use it to solve this (I've got ISTA, etc). Engine has no codes.
I'm thinking my TPS, throttle stop, cable slack etc might be wrong or out of sync causing it to dance between detecting fully closed throttle and 1-5% open. Anyone have a source on the procedure to set this up properly? (My TPS has been replaced, no change).
I think I have a small exhaust leak on my rear header flange after the o2 sensor, possible this is distorting the readings? Doesn't leak at idle, only under load.
MAF? ICV? Any other ideas?
