LS1 Random Misfire Problem
Recently my car developed a "Multiple Random Misfires" code from the CEL, in cylinders 7 and 2. I pulled the plugs, wires, and coil packs, none of which helped. Checked for vacuum leaks and didn't find any. Tried listening to an injector, and injector #7 turned out to be sticking. I just replaced #7 with an OEM injector, car ran fine on start up, but after a few prods of the throttle it started misfiring again. Any ideas what could be causing this? Taking it back to my mechanic tomorrow to see if there's anything else blatantly obvious it could be, but I'm in a definite bad spot; the car's my DD and I Need it back running properly, ASAP. Anyone who's had the same issues, or any advice please let me know! Car's an '00 so it has the 26.4lb/hr injectors
