ill let you know
If its your coil packs the car will misfire, at least thats wut mine did when one of my coil packs went bad. My impala use to stall out after start up and i replaced the mani o2 senor and that fixed it, u might wanna replace the o2 senor near the cat conveter. Or it could be a vac. leak.
