Its a 1997 pontiac grand am gt 2.4. Car ran like it was running on 2 cylinders and threw a p0300 code but didnt throw a specific cylinder code. I changed coils and plugs and now the car just cranks and is shooting smoke out of the throttle body. Smells like unburned fuel (hope that's all it is) I heard a rumor that new coils with an old timing chain the timing can sometimes jump. Ive tried putting the old coils back and I checked all the fuses. And I kno it could be crank sensor but im unsure as to whether or not that would keep it from running
have the same problem?
