Hi friends, i've a problem please help me...
When i start the car, and the engine is cold, the Exhaust makes some pops and crackles, then when the engine becomes hot the problem seems to disappear.
I've read something about it, and today i remove and clean the Throttle Body and MAF Sensor (CRC maf sensor spray) following this guide:

After re-mounting all the problem seems to be less but not disappeared.
So i decided to order, according to this guide (
Porsche Boxster Mass Air Flow Sensor (MAF) Replacement and Troubleshooting - 986 / 987 (1997-08) - Pelican Parts Technical Article), to buy a new MAF sensor with the same code of mine 996.606.124.00 (i've a 1999 Boxster S).
It could be the MAF?
Another symptom detected after an aggressive driving is that the TC LED turns on (goes in failure)...it can be that the ECU is not being able to manage MAF (damaged??)
Reading the ECU with my bluethoot sanp-in and Torque no errors where find.
It could be lambda probe?
it could be the ignition coils or spark plugs (may be never changed)?
Please tell me some about it, and excuse me for my bad english...
