Cold starts back

Hi Al.

Congrats on the race! Hope you've recovered from the speed high and the testosterone high with that magazine model! Winning definitely has it's advantages eh?

I have your Fireball 2 flash with Buschur stage 2 except I don't have their Mass Air Pipe. Power is awesome but recently I'm having problems with cold starts and rough idle. I do have a CEL 0420 (inefficient cat) that should be corrected with the addition of the O2 simulator Buschur provided for me. I've cleared the code by removing the battery lead without any improvement. I also drive quite a bit (Now 29K miles, 7K since the flash in two months). Any suggestions on what it may be? I'm thinking maybe my plugs are fouled or need replacement, or some possible injector problems? Thanks for the help and I'm looking forward to a custom tune once you get to MN! We have a number of guys interested.

I would check first for any vacume leaks in any of your connections

basically the reflash does not touch idel at all. We do see some cars on ocassion with idel problems and most of them had vacumee leaks.

The best way to find them is to test the system with pressure

We even saw one with a small rock hole in thye fmic which created a rough idel

Basically do a basic trouble shooting on the car and you may fine something
