Spyder Air/Fuel Ratio

[SpyderGS1997]

I have been having a problem with my engine wanting to shut off or misses really bad...whenever it does it the air/fuel ratio shoots as far as it will go on rich. Was wondering if this is a mas air flow sensor problem or possibly o2 sensors. Has anyone else had this problem? If you have let me know what you did to fix it...thanks

well mines a 90 tsi and my A/F goes to about the 2 oclock position then back down to lean and back and fourth, i donno what it is with mine.

take your airfilter off and make sure everything is ok with your MAS

I'm not sure if your car is a turbo (you should fill that in) But if you popped an IC pipe, or have a large boost leak, that would definitely do it.
