Message	IF you have a Sticking Injector ( clogged ) The ECU will richen up the other 2 injectors in that bank to try and Compensate for it.. this will cause these cylinders to run Rich and LIKELY wash oil off the Cylinder walls and Smoke .. LIKELY the problem is on the 'Lean' side of the engine.. SOMETIMES the Injectors can be just exercised back into function.. ( Some shops can do this on the Car ).. Sometimes they need to be pulled. At Idle, Do a cylinder Ballance Test to find the LIKELY problem.. then go from there.. You have an Aftermarkett ECU so O2's Might still be working at Idle.. that MIGHT complicate the ballance test a little.. If you cant get a good ballance test ( Car runs like Krap and not stable when you pull One Injector Lead ), you might have to pull BOTH o2 Sensor leads to force Open Loop Idling, before doing the ballance test.. ECU's are fairly robust, so my take is it's unlikely that it was wounded when jumping.. Does this ECU have any Codes you can read?.. Cj
