BRN-EVO

I had a cel about a week ago and I took the car yesterday to scan the error and it was from the idle control so I cleared it. I drove the car for all day and tonight when I came back as I turned the car off, the cel came back again since I have a turbo timer. The cel came out at the same time when I turned off the switch.
The guy that checked my car yesterday said that nothing is wrong with the plugs or anything.

What was the trouble code number. Have you had the turbo timer installed for a while before this happened? Does the car feel as if it stumbles or do the rpm drop at all?

I've installed the turbo timer around 8 months ago. Actually, I dont notice any change in idle or rpm. Could it be from the intercooler? Mine is a 3" ETS with lower pipe.
