I got a misfire cylinder 2 code here is the story.

the car gave me this code about 4-6k miles ago, so I changed the plugs code did not come back until a few weeks ago. so last weekend I figured I'd swap the cols from cly 1 and cly 2 to see if this cured the problem or if the code would move to cyl 1 (making it a coil pack problem) and the plug looked good, well it did not move still reading cyl 2 misfire

so I swapped injectors 1 and 2 dove it for a while engine light stayed off the next day will driving around it came back on, so I swapped plugs 1 and 2 looked at them booth neither looked any worse or better than the other checked the gap on both and reinstalled. Drove it to work yesterday no light drove it again this morning and it came back on, same code p0203.....any more ideas? oh one other symptom after the engine light comes on the tranny shifts hard.

Long shot here but the Pontiac was idling terrible a while back. Found that by unplugging a harness on the throttle body, it idled fine. However, the trans shifted really really hard while it was unplugged. Before digging into the electrical, I decided first to clean the Tb. Everything was back to normal. Got lucky I guess. Hope you do as well.
