drive cycle for 2003 mustang GT
I took car down for emissions testing and this is after I had a CEL which I think I fixed. Think it was a dirty MAF sensor cleaned it with alcohol and a q-tip. Usually the CEL would have come back on by now cuz I have already driven car 81 miles since unpluggin battery. The light usually comes back on within 15 minutes of idling in the garage so I think I took care of the CEL problem. Anyway my question is the car will not pass emissions at 81 miles of drivin after battery unplug. The two things showin up is catalytic and EGR=NOT READY. How far do I need to drive or what do I need to do to get these two things in ready status to pass emission testing?

I don't know how your laws are wherever you are, but in Texas, you can have two systems not ready and pass. Just go to your inspection station and ask em, my local station will test the car for free to see if it will pass.

I doubt the CEL will come on again because this car is supercharded with a saleen series IV twin screw and I had no problems after installing it but when I started messing around to going to a bigger MAF I would get a check engine light. Messed around with that for a month so the stock MAF sat out in my garage wires facing up for a month so I am sure it was dirty considering liviv in a desert out here. I would get a cel light after 30 min of idling in garage. So I took the stock back out clean it with alcohol, have idle the car about 6 times in garage a couple of times for 2 hours and now have drivin it for 81 miles, No CEL has came on yet and I am down to two not readys on the emission part of drive cycle.
Car sit in garage most of the time cuz it has been snowin here n salt lake city. My registaration has expire 3 mnths ago and I miss drivin the car on clear days. Supercharger+4.10 gears+Snow bad combination.

I am sort of fuzzy as to why you think we would be "gettin what Im sayin" when there was NO MENTION whatsoever in your first post of the information put forth in your 8:04 pm "yesterday" post?
Sounds to me like you bitched up your system by installing a "bigger MAF" and not altering the tune to accomodate same--why you thought that would work is an enigma to me, you need to do some reading as to how modern EFI systems work.
Contrary to what you might think we do not follow your exploits that closely, nor do we read minds--next time you have a problem you might want to list all the parameters right up front and waste far much less of our time and yours!
