I have an 03 coupe.

Recently, when I start the engine in warm, its starts then stops.

My friend said it could be a MAF problem.

How hard is it to remplace the MAF?

Is it really an MAF problem?

 

can you give us more details please?

do you have an aftermarket intake?

what are the RPMs at?

 

Everything is OEM. My car is not modded at all.

One day, I start my car, it starts, then stops RPM at 0.

 

First try to reset the ECU. Unplug the battery for 30 min and see what happens.

 

sounds mroe like a throttle body issue.

 

hmm .. should I bring it to the dealer? I have no more warranty though ...

 

+1 on the the throttle body. It needs cleaning. It's not really anything critical, but starting the car up twice is annoying after awhile.

here's a link...

The thing is that is starts well when the engine is cold. But when the engine is warm, it does that problem. My friend says its possible that the MAF sensor is defected ... ? I called the dealer to see how much it cost for the sensor ... its 300$ .... Does anyone know where i can order it for less? Im in canada by the way.

 

I had the exact same problem.
I used a MAF sensor cleaner, and it fixed the problem..

 

Nice thanks! I'll clean the throttle body and check it out!

 

where can i get a sensor cleaner? something special?

 

CRC Mass Air Flow Sensor Cleaner

Can be found at most autoparts store. If one doesn't have it, try another, it is relatively common.

 

Problem SOLVED!!!

Clean the Throttle Body!!! and everthing is back to normal.

Thanks all!

Thank god I didnt go to the dealer, it took 30 min just to fix it!

 

good job man,

...surprising how much carbon build-up it accumulates in there right?

 

Yeah it was hell dirty. Thanks for pointing me at the good direction!
