unknown electrical problem

[borisboem]

Hey all, want to ask you about my problem with my boxster S, 2000. Another issue with the mass air flow sensor, or not?

My boxster S, 2000, has a problem, bad running engine. Before, few months the problem was solved after resetting the DME but now its permanently. After starting, the engine runs 1500 rpm. max and its not reacting on the gas-pedal. A kind of emergency program what he is running/ doing?

I changed the MAF sensor without result. Now the dealer is advising to change the whole gasunit, dont know the english word. Its 800 eur. and i am not sure if this is the cause of the problem.

Unforgenatly i dont have a boxster with a light of electrical codes on the dashboard display.

Any other idea??

Sorry about the mistakes,

thanks, Boris from the Netherlands

You need to get your fault codes checked.

Is the CEL on?

thats what they did at the porsche garage, unforgenatly cant check myself those codes, this model doesnt give this information on a display. Cel?

The OBD II fault codes are the key to helping you.

Can you ask the shop to tell you the codes?

Hi,

Still no OBD II codes,dealer not working in weekend here.

Forget to tell, when i disconnect the Mass Airflowsensor, the car is running ok in an emergency program, also gas pedal is working. Also no "check engine" light on dashboard. So you should expect the problem in this MAF sensor, but not.

Obviously i am not driving with this emergency program.

Hope to hear u again,

Boris

I would remove the throttle body and give it a good cleaning. That might be what he is trying to replace. It is a common problem that they get gunked up over time. I highly doubt that it needs to be replaced.

merci,

I think thats the word of the part i was looking for, the throttle body, what i called gasunit/ gas valve. Stefan, what is gunked up? is the valve not moving up and down, or do you mean something else? And how do i/ they clean this?

But if this throttle body is the problem, why the car is then running ok with the MAF disconnected? Do u have an idea?
