Re: B21 K-jet woes... 200 81

Hi, John!

Back again...

"I don't think you have a O2 or frequency valve problem. That system isn't suppose to be able to cause

enough difference to be noticeable by the driver. It's strictly a fine tuning system. "

Just thought I'd let you know directly that I followed up on the suggestion of Jim's to look into the frequency valve. You can read more about it in my reply to him, but when I pulled the harness connection off to measure voltage in the harness to ensure that it was getting juice, the motor really bogged down and stalled. Maybe it's that the Lambda adjustments made by the O2 sensor and ECU are indiscernable by the driver; but when the frequency valve was rendered inoperable, the motor really pigged out.

I'll get some Techron and run two bottles through and see if the problem goes away. (Cross your fingers for me...)

Thanks again for your help!

Rob
