W202 C200 MAF Problem
 

I have a puzzling problem.
Car goes perfectly.
Except when it is warm and I have parked it for 15 minutes or so. Then for the first km or so it misfires and stalls. After that it is perfect again.
Now that summer is here and it is getting warmer it seems to be worse.
So yesterday I disconnected the MAF sensor and the car was perfect for the whole day.

I would replace the MAF but I am short of funds.
And I have read about all the wiring problems on old W202s.

Could this be a wiring problem?
Or should I just swap the MAF?

Regards
Paul
