Default Strange misfire issues when the car is cold..

A few times now (maybe once a week), when I start the car in the morning, the engine shudders a bit, engine light flashes and pulled codes indicate misfiring (in cyl 1 I think). This happens for about 10 seconds, after which the engine light stops flashing (and goes away) and car then runs like normal.

Any idea what may be wrong? The only thing I had done recently was a timing belt / water pump and suction pump change... The CP's were replaced maybe about 15K miles ago...

Car drives fine and runs like a champ otherwise..!

I'd say CP # 1 is on its way out

Default Do you think it was coincidence that it happened right after the timing belt? What about..

... the spark plugs..? This sucks..

na, just random CP failure. I'd replace the plugs and that one CP and see if it cures it

Default NGK is a decent one, i think the stage colder set were like 8 bucks for 4.

I looked up the part number online and went to advance and they had em in stock. However, i think they only lasted about 8k, as my fuel economy is slowly dropping. I can only assume its the plugs on there way again.
