Well, 6 weeks ago my CEL came on. I checked block 032 and my long-term trim values were 23%. Plus, the car was idling funny, and had the odd misfire during startup.
I cleaned my MAF, and this helped tonnes. Didn't get misfires for a month, although my long-term trim was still 17% (more than the +/- 10% spec).
Then two weeks ago the car wouldn't even start. It bucked and surged and sputtered...so I assumed it was the MAF and I was right. I unplugged it, and it drove like a dream
(although my ASR light and CEL lights were on 
)
I picked up a new MAF $102 +tax! What a steal!) and stuck it in. Idle was much better, although when I punched it and got into the upper rpm's my ASR light goes on and I got the code:
16487 - MAF Sensor (G70): Signal too High
35-10 - - - Intermittent
Drivability is not affected. It still pulls like a mofo up to redline.
(From what I've read, the ASR light goes on for non-emissions related engine problems).
I went back to my garage and got a 'loaner' MAF to see if indeed the new MAF was defective. I drove around last week with this loaner MAF, and had no problems (I was at WOT ripping up to redline on many many occasions). This somewhat proved that my "new" MAF was bung, so I returned the loaner MAF and got another brand new MAF.
...and of course, the first time I floor it with the new MAF (definitely not the same new one as before ) the damn ASR light comes on and I have the same fault code as above.
Grrrr...
Block 032 shows long term trim at -14%...
