Check Engine Light Update

[rainmaker]

I took the car to the shop over the weekend to (1) have the lower control arm bushings installed and (2) diagnose check engine light. I also complained of a slightly low idle speed (around 490-495 rpm when warm/hot).

Got the car back earlier this morning.

The lower control arm bushings weren't installed as only 1 bushing arrived (an apparent miscommunication between Service and Parts). Hmmm... Have to wait another week (or two) for the parts to arrive.

They checked the car over with the HHT. The Check Engine light was reset as well. The tech wasn't able to give me the fault codes that cropped up but 'translated' it for me. (Although I insisted on getting the fault codes, but I guess he thought he knew better. Hmmm...) Anyway, here's what he wrote down:

Problems:
- Idle speed control
- Intake air temp sensor

A further notation read:
"Control Module EFP N4/1"

Can anybody translate this into English? Jim, are you there? You seem to be the expert here.

Problem with not getting the original fault codes is that I can't reference what he wrote down with know fault code interpretations and fixes. I wanted to learn more about this car...a critical part of ownership I always believed...

The good news is the Check Engine light hasn't come on yet although I have driven the car extensively today.

Many thanks...
