Any advice, poorly running Boxster - 986 Forum - The Community for Porsche Boxster & Cayman Owners

Sounds MAF related to me. Try cleaning it. You could also unplug it to see if it runs better. Be aware that when you unplug it the car will throw a CEL because it is unplugged. I'm not sure if the CEL will clear itself when you plug it back in or if you will have to clear it with a OBD II reader.

Ok, I will try that tonight. Is it possible that some of the foam screwed up the MAF? Thank you.

It's very possible, the wire on the MAF is fragile. Just too much oil from a k&n filter has been said to ruin them. If you try to clean it get the MAF cleaner spray. Don't touch any of the parts that go into the intake. Just spray it real good and let it air dry.

Will do. Thank you.

Unplugged the MAF and it ran 100% better. Removed and cleaned the sensor(twice) and it is much better. Still feels like it is a bit doggy but at least it will get down the road now.

Thank you very much for your help.

I'm glad I could help. Cleaning it doesn't always work. New ones are pricey. If you do get a new one, take out the old one and write down the model number. There are a few different models and you need the correct one for your car. I would stick with a Bosch brand one.

Yea, mine was an older number but the Pelican website helped me sort it out. Finally got the engine covers back from my mechanic today. Road test tonight.!!!
