The guy at the parts store said these were copper core and a step colder. I will get some of the TR6's. Is that what you are running Trapps?
There was no error on the display... It acted like it was going to run rich and then went lean for about 3 seconds and I shut it off. If I recall correctly it did not automatically shut off after running lean, it happen so quick it is hard to tell. The car was running like $hit but still moving. Good thing I was at the end of my driveway.
