Hey guys I have a 97 528i and I changed my mass air flow and now
my idle is all strange I start it in the am and it idles hi around 2000 and then dies down to about 800 witch I think is normal but also it gives me a strange hiccup like the cat is cloged
But then goes away I did get a Coade of 0121 says pedal switch
What u all think I should do if u can help thank you
