I use carb cleaner and saturate it then with rubbing alcohol.
Leading evidence: 'Use carb cleaner and saturate it' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Clean process' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.
Source reports, not a diagnosis or a success probability. Counts refer to discussions and can overlap.

Suggestion
Original diagnosis was that the Lamda's were shot, so had them replaced (�400..ouch) and it's no bl00dy different!...according to an Indy specialist here in the UK, it sounds like it's almost certainly the MAF, but would be interested in obtaining a reading and cleaning it first!

Suggestion
Ooops, second question (sorry!)....when I replace the MAF, will I also have to reset anything in the OBD?...Up until now, because the MAF is failing, apparently the Lamda's try and compensate, but run out of range, then log a Lamda Fault in the OBD (erroneously, it seems)...does this HAVE to be cleared in order to fix the problem, or will a reset at next service suffice?

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

My 996 air flow sensor has gone bad; any of you fine folks know where I
can get a replacement? Can you diy easily or do you have to re-map the
computer after installation? So say a local So. Cal. shop.
Thank you in advance for the any info!

Plenty of online places to get the Bosch MAF for about $220. Why do you think you need a new one. Needing a new MAF is a common fallback for the Dealer. They can be cleaned. What is the reading on your scanner?
I use carb cleaner and saturate it then with rubbing alcohol. Electoinic's spray works well too. Find out what it is reading first by using your scanner. Then you can see if the reading improved.
How did you guys get a reading of 97% ('scuse my ignorance here!!)...are you using the PSM-II module to plug into the diag port?
Interested because my C2 is about to have a new MAF installed, symptom being that there's hesitation throught the rev-range when under full load. Original diagnosis was that the Lamda's were shot, so had them replaced (�400..ouch) and it's no bl00dy different!...according to an Indy specialist here in the UK, it sounds like it's almost certainly the MAF, but would be interested in obtaining a reading and cleaning it first!
Thanks

Cheers (again) and sorry to hijack your thread 2na

Most good scanners should not only be able to give you the MAF voltage but the airflow in lbs/min (or whatever units you prefer). Using this information you can calculate what percentage of the total possible airflow the engine is capable of is being supplied. Alteratively (if you don't like math) some scanners will make the calculation for you and make a nice plot of the volumetric efficiency...like this:
This graph is at full load. That's the only way to measure VE.
When the throttle plate is nearly closed, like at idle, I measure around 0.75 lb/min of air. I get as low as 0.73 as as high as 0.79 lb/min.
Ausgezeichnet Ubermensch! Eine Frage bitte...
You have just the PC-based OBII Scan Tool, right? And not one of the bundled pro offerings, correct?
By the way, where does it attach to the car?
Again, thanks.
Yes, I'm just using the PC-based tool that connects at the OBD-II port by your left knee while sitting in the drivers seat. The software is simple, effective, and valuable if you're an engineering geek like me
