I checked the archives, did not find a solution:

Last run yesterday was a 45 mile jaunt, so the lawn mower syndrome can be ruled out. This morning, I had to crank the car, probably 45 seconds, to get it to start. The last 35 or so was with the throttle pedal to the floor, and then it was rough running for several seconds until it cleared out and ran fine. Every start since then today was hard, but not that bad, maybe 10 -20 seconds. The longer the car sat, the more difficult the start.

This afternoon, I checked for codes, A2 and A6 were 1-1-1. I cleaned the MAF, started the car and ran it a minute, then left it alone for an hour. Then it was hard to start again.

I pulled the plugs, they look OK< but have about 30K miles, so it's about time to change them. Plug wires (Bougicord), cap and rotor (Bosch) are all under 3 year old. The FPR is about a year old, as are the vacuum lines and PCV system. All seem to still be connected.

Any ideas where to start?
