Thank You Ruiner WOW, a real easy 30 minute job and the results in one word "SMOOOOTH". The cold start sputtering is gone, the throttle response is definetely improved and the engine runs so much smoother. I think this is the best return on investment I've ever gotten. A total of $15 including the Torx driver. The only thing you have to be careful about is which cleaner to buy. There are some that leave no residue but are not safe for plastic which is what the housing is made of. I ended up using the one shown which I found at Home Depot. Thanks again.

 

Those bends on the MAF circuits do not look good at all. I wonder how they happened...

 

My guess is it happened when the dealership took out the Y-Pipe and shipped it to Stephen to be moddified to fit with the 996 NA throttle body. Hopefully they will buy this and give me (another) free MAF. If they are game or not, I think I'm moving along to the Boxster MAF. I'm surprised the car will even run with the bent wires!

 

I installed the 986 MAF today as well as a no oil cotton filter (thanks Todd). The jerkyness at very low throttle seems to be gone!

 

Have I missed something here?
Why the 986 MAF and not the 996 MAF...?
Is it better....? Does it really fit!?!

 

It fits, BUT..........it is not typically recommended as a replacement unless you are at Stage 4 (?) or higher and pushing a lot more air through your MAF than what that standard MAF of stage 1-2 MAF would see.

 

Ruiner, I am having the MAF issue now. The code was P1101 and and am having it replaced tomorrow. I am running Stage IV for about two years and did the new EVO intake with the new oil-less filter about 300 miles ago. Should I replace the MAF with the 986 because we tried cleaning mine and the car threw the code again and will not go over .6 bar of boost.

 

From what Stephen @ IA said, the 986 MAF should be used if you are running larger turbos and are pulling more air.

Stephen, feel free to correct me if I am wrong.

As for you only pulling 0.6 bar, it almost seems like you have a vacuum leak of some sort. Perhaps a hose/pipe has a small crack? Are your diverter valves failing?

By the way, what does P1101 diagnose as?

 

P1101 is MAF failure, I agree about the vacuum leak. I am servicing the car tomorrow and will let you know what happened. I am going to see if they would install a 986 MAF tomorrow at the dealer. I hope I resolve this issue tomorrow.

 

Tony playa,

I need to check your car for a boost leak tomorrow

 

Thanks Ron, and thanks again for helping me out today on such short notice.

 

no need for thanks Bro...always my pleasure!

If there are no obvious leaks I will break out the smoke machine, works every time

 

I have alway enjoyed doing the smoke tests on my old turbos. So simple, yet so effective.

 

Ahh reviving this thread haha.. Just wondering, i have the same symptoms, partial throttle in first accelerating it feels like it hit a little dead spot then keeps going, and under full throttle in 2nd or 3rd the car like sputter midway through the power range then bursts with power again.. I should definitely clean or change my MAF sensor correct? Thanks guys.. Martin

 

martin,
would i lead you wrong? clean your MAF. it's a simple fix especially with DIY instructions on here
