MAF / Hunting Idle / Loss of power


Recommended Posts

After putting in a new MAF I had a loping Idle problem.... I was told it may be the MAF so i put in 2 other ones of the same correct part Number and I still had the hunting Idle.

Finally I gave in and took it to the dealer After $625 he put in a MAF same Part number and the hunting idle is gone. I dont get it.

Anyway I feel like I have lost power along with the new MAF, has anyone else experienced this going to the new

986 606 125 01

The idle is fine and there is No CEL but i feel a loss in power, not the same PEP, im wondering if there are others who have noticed it or if its in my head.

Thanks for your expertise !

I just read the work order from the Porsche dealer, those clowns put in the wrong MAF 996 606 124 00 , I called them and let them have it.

They came by the office to put the right MAF in 986 606 125 01 and when they did. The Idle problem was back...... Back to the drawing board.

The MAF they put in was robbing my power because the fuel air mixture was set for a bigger block.

The car is at the dealer now and their saying when I put the new MAF in myself the DME was not remapped. I told them that My car didn't need that because

TP told me it was e gas. But it seems as though I know more info about this issue than they do.

Will keep you posted, if you have any suggestions on how do deal with this crap I would like to know.

TIA

Did they upgraded the software of your ECU?

There is a technical buleting that mention that. If you go from a 00 version to the new 01, the ECU need to be reflashed with a newer software version that can deal with the different reading that the 01 will provide.

I had the same problem that you had, I think that that idle control valve was the problem (dust, rust so it become sticky... the dealer chnage the whole throttle body (I have a E-gas car)

I told you you would end up going to the 00 MAF, there is a problem with some Boxster's and the 01 MAF without a patch being done.

BTW - the reason you were running better with the wrong MAF, was due to the mixture probably giving the Boxster a more rich condition - thereby giving you more "pep".

Due to our ECU Mapping, Porsche intentionally leans out our vehicles to meet federal smog standards.

Porscheneer - did you get my e-mail about your hood latch.

Thanx guys actually it was not the MAF nor was it the ECU upgrade flash. The 01 MAF I had in there was correct.

The Throttle body was gummed up bad, so the gate kept opening and shutting trying to breath at idle so they cleaned it out gave me my money back for the extra MAF with an apology and a 996 for 4 hours while they fixed it. It may have been because I gave a quick call to the service manager.

Scott I did get the email and I mailed you back buddy...... it seems as though the hood problem is not that bad for now .I can get it shut on the 2nd or 3rd try

My biggest problem is I cant get the 996 out of my head I need more power I have to look into uprade from a 2.7

but in all im happy this drama has come to an end.

Thanx to all for your help
