Wait, first..... Are you a chick or a dude??? Seems like we get that a lot here......

I take it you are boosting? Whats your PSI? Have you done fuel upgrades?

^ LMAO........You both should be SG members.

I'm the husband. no boost running N/a modified. Just internals

No need for SAFC....

a bit scary...you cannot use your car until you solve the problem..in my opinion. (you probably know that)

i would get it scanned and check out the o2 sensors. o2 sensors are the most likely reason

You said you are not much of an engine guy yet you have forge internals? Did you do the work yourself? Maybe thats the problem there. I am not being mean so don't get me wrong, But maybe you should tell us more.

i had a friend who is a mechanic do all the work

I don't know what a "scangauge" is. I will assume it is either a wideband o2 sensor or a code reader for the ECU you used when you got a MIL. At any rate, I presume your car is a V6 since you are talking about no S/C. Is the mixture lean in both banks? If it is, it is likely something to do with that Safc you don't need or the MAF meter, these cars almost always go lean in one bank or the other because the banks are trimmed independently. If it is only one bank, check for vacuum leaks, especially around the injectors.

PDX SuperSolara your the man, I think. I just read the code from my computer and its a 0171 which is bank 1 running to lean.
