Chaps,
I'm on Air flow meter number four within a period of a year!!! The original showed up as faulty a few months after I bought it as it was running terribly, so got it changed for another which has been replaced twice since. Symptom tends to be a gradual lack of torque/power over a period of weeks and then a sudden misfire at around 3500 revs. It seems ok when the engine is cold but awful once it warms up.
Having just had number four fitted it has been magic for two days regardless of temperature but dare I say I think it might be playing up again when the engine is warm
Has anyone come across this or have any idea why they may be breaking down so quickly??Their not OE but sourced from a reputable supplier. I'd accept one new AFM may have a manufacturing fault but not 2 or 3!

Its a fair point but you would expect "as close to OE as is possible" would at least last a tad longer than that and would you not test the quailty at least?? Having said that if their supplier or someone in the chain changes it up that would blow that theory out the water. Probably should know better really the dizzy caps and arms I bought a while back look they came out a cracker. I bought OE stuff in the end and all was fine......jesus with a bit of prompting I just answered my own question
I might look for a second hand OE one then, I think SS has one on ebay.

I have an OE one in good condition for sale. I also have the bigger 20AM upgrade if you like
Also check the wiring around the afm and tps. I had the same symptoms as you, turns out 1 or 2 wires had tiny holes/cracks and was leaking current or grounding at higher rpm
Good man thats worth a check...I'll PM you about both as I'd like to chip and tune anyway.Also check the wiring around the afm and tps. I had the same symptoms as you, turns out 1 or 2 wires had tiny holes/cracks and was leaking current or grounding at higher rpm
