......Just thinking recently alot of people have been experiancing peoblems with there idle control valves. If it is not working properly "maybe" the fuel mixture is off. I know the boost is controlled via the map sensor and air/fuel mixture via O2 sensors. Realistically the a/f mixture would be off if someone had a very slow reading O2 sensor. NG are known for having very slow responding O2 sensors. This problem was corrected with the t-7 ecu, just our luck. The only way I know of checking for a slow responding O2 sensor is via tech2. Abbott racing told me there was a way to clean old o2 sensor to improve performance but I can't remember it at the time. If someone wanted to clean there idle control vavle a quick shot with carb cleaner will do the job. Its a very, very, very, very, very slim chance of clearing the problem but only takes five minutes to clean and cost a dollar or two for a can of carb cleaner. Not sure if this helps anyone but I thought I throw it out there anyways.
