Well normally if it was an issue with the cats the rear 02s would throw some sort of code as well because their only purpose is to monitor the cats performance.
I would say back to the tuner.. Bad tune

I'm going to ask a strange question. Have you had your transmission out lately, or been messing with the speedo? My car was giving similar codes and it turned out one of the speed sensor plugs on the tranny had a wire pin pulled out of the plug. It was sending voltage back thru the system and messing up the mixture. The dealer said the code was saying rich when in fact it was actually running lean. I know nothing about this, I'm only repeating what they found but, your situation sounds similar so I thought I would pass it on.

its pretty hard to get a rich code out of the fronts.
are you tossing black smoke under throttle?

its never been to a tuner, the tranny was out, but that was like 8 months and 6k miles ago (ill check that out tonight), plugs dont look bad, ill look at the connection on the tranny, and i got got behind it this morning in my mach and had my woman take off hard and no black smoke, when i put my hands over the tail pipes there is hardly any pressure comming out, not as near as much as my mach1.
whats the actual code number?
If running rich, it was either a PO172 (Bank 1-System too rich) or PO175 (Bank 2-System too rich).Orange Stang 04 said:

you are correct sir those are the codes that it threw at me. could a dirty maf be the cause of this?
4a7191a, I am not sure on that but cleaning your MAF certainly would not hurt.
Perhaps some here that do know will get around to responding.

thanks, ill be tring to figure it out thursday when im off again, until then ideas never hurt.
You are familiar with 'How' to clean your MAF?

now she just called me, and at a red light with a smooth idle it idled down and died, but it started up fine, and runs good still, she said it did this twice.
damn

By chance, have you cleaned the MAF yet?
I found some material online that indicated that a fouled or 'dirty' MAF could throw a "System too rich" code for either bank.

not yet, im goin to get on that job thursday
Thats cool.
Please be aware that I am not saying that cleaning your MAF is the cure-all of your issues/problems but that it simply will not hurt to clean it. Other than that, admittedly, I am clueless because I have never experienced what you have described. Replacing the O2 sensors might be a future option, as well.

i know it was mentioned before, but did you check that speedo sensor in the tail of the transmission? i unplugged mine after gear install before i got my tuner so i wouldn't rack up miles. once in a while when i would come to a stop it would very calmly idle down and die. strated right back up no problem. your case just reminded me of this. hope you figure it out.

ironically after installing my Bassani Catback I have been getting a System Too Rich Bank 1 code also. I had an exhaust leak before the passenger upstream 02 where my paper gasket blew out so I replaced it with a metal OEM gasket and cleared the code. Nevertheless, the code did return.
I also installed my JLT CAI 1-2k miles ago and I cleaned my MAF when I had it all apart so maybe it's time to clean it again and see how it works out for me. I am also going to check my speed sensor plug and I will get back with you and let you know if it works.
When are you getting the code? Mine only pops on when I am cruising at at least 60 mph.

well problem fixed , i put a new pypes catted x pipe, which may i say is nice, the problem was still there, but it was running better (a whole lot better), so i pulled the jlt, and cleaned the maf, and put ther fipk k&n kit back on, problem gone, im not sure where the problem came from either the jlt or kinda dirty maf, which it was cleaned less than 1k ago, but its fixed, any one want to buy a used jlt????
