I was able to resolve it by cleaning the MAF with a circuit board cleaner as suggested by a posting here.

I tried the cleaning and the CEL came back on the next running with the same issues.
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Hi All,
I've been digging around for an answer to my idle & CEL issue and have found several topics, but none match exactly what I'm seeing.
The CEL came on about 6mos ago with p1123 and p1125. I was able to resolve it by cleaning the MAF with a circuit board cleaner as suggested by a posting here. I did not notice anything wrong with idle or acceleration at that time.
It's now come on again. I've noticed difficulty at start up. The throttle response is poor right after start up. I have to play the gas just to get the RPM's up. In addition, once warm, if I step on the gas hard the car bogs down. If I gently run up the speed there is no problem with acceleration, but I can't punch it.

I found a posting that suggested unplugging the MAF to see if that was the problem. I can now hit the gas after the engine is warm and the car really moves again, but it didn't solve the throttle response at start up. I would say it's almost worse.
Does any of this help point to the MAF failing, or something else?
Thanks,
I thought I had the same problem with pretty much the same symptoms. The dealer also diagnosed it the same way. Took the car in and found that one of the hoses had a hole in it. Replaced it and everything is fine.
Sorry for the delayed response. The car is a 99 non egas C2 Coupe. I have a code reader, it's the basic model. The codes are p1123 and p1125.
I've kept the MAF unplugged since this post and the throttle response is SOOOO much better. Just ordered one from Paragon Products. Way better price than the dealer. Even beat Sunset.
