'90 525i (M20)
As some of you know, I've been dealing with a "stuttering" "check engine" problem for some time....I recently had a major tune up...and also the O2 sensor replaced, and the car definitely runs better, but every now and then, especially in traffic, I still get the hesitant stutter and sometimes with the A/C on. I'm wondering if it's ok to purchase a used Air Flow Meter.....I see one on ebay for $40 and that's a steal comapared to the $300 (plus) that Bavauto and BMA parts wants....
Has anyone had to replace this item, did it correct your issue? Advice please.
Thanks
