Just got my headers and A@A set up on this weekend everything seems fine but the check engine light is on. Has anyone had this happen? :confused:

Yea, often, what code and problem do you have. I got lean conditions

Hasn't happened to me, but you should definitely pull the code. There's a how to over it tech tips. :cheers:

Had a scan done the shop said it was running rich, I had them reset it and see if it comes back. Can this happen to new programs Ed Wright did the program it may be rich just to be on the safe side. Can this hurt the car?

Running rich will not make the check engine light come on, atleast not until the plugs foul and cause a misfire, if the light comes back on you need to find out what code is coming up in order to fix the problem :cheers:

It actually will under some conditions. I actually had the light intermittently being set with a "bank too rich" code under very light throttle (usually in a high gear), after I went to the single intercooler setup and did some upgrades to the fuel system. It went away after I leaned it out with the injector flow rate table. It was really odd, because the data did not show that it was running all that rich. I never went back and tired to figure it out, since I needed to lean it out anyway.

The code is po172 too rich fuel bank 1 I had someone say this could be a program problem or it could be a leak in the vacuum. I had the code reset but it came right back. Its hard to have just get the car back with the blower on and not be able to run it. :banghead:

Just call Andy at A&A, he should take care of you :seeya

Found out what the problem was. The new fuel pump is very strong and keep the fuel rich. We had to adjust on the dyno and the car made 525rwh with 5 1/2 lbs of boost. :party:

Glad you got it worked out :party: :party:
