I would start by unplugging the MAF Boxsterra - Sunday, 17 June, 2012, at 11:51:32 pm |

Hello my friends, as I stated on the tile I am having major problems with my 02 boxster, it is a base model with 160k miles, de-snorkled, and K&N filter(installed 90 miles ago) Here is the whole story:
A few weeks ago the after I installed the K&N the car started stalling and it would shut off by itself, I took the MAF out and cleaned it with MAF cleaner which worked great because the car stopped shaking. A week later the car felt slower so I hit the gas to see if I felt a huge difference in power and about 6800 rpm the engine completely stalled and all the pilots appeared on the dash but disappeared in a few seconds. After that, the engine was shaking and stalling like crazy, when I hit the gas it would start to backfire through the intake and then it would just shut off. I tried cleaning the maf again but with no luck. The car does the same thing everytime and it is imposible to rev it over 2k rmp without the car shutting itself after a few intake backfires. The car doesn't has the "check engine" or cel light on. I disconnected the MAF then started the car and it runs the exact same way as with the MAF connected, there was no noticeable difference and it would still misfire, stall, and shut off.
My question is, if the MAF failed, would the CEL light come on? could the MAF be the cause of the engine misfire and the intake backfire?
I also read that it could be the coil pack, fuel filter, an intake leak, timing chain tensioner failure, or the timing being way off.
If you guys have any guidance to narrow my search it would be greatly appreciated, I was thinking on going ahead and buying a new MAF but the fact that the CEL hasn't come on makes me think that it might not be a MAF problem.
Thanks a lot for your time and have a great day !

You can get a new MAF for just over $200 Boxsterra - Tuesday, 19 June, 2012, at 12:38:40 pm |
There's always two problems, unless there's just one or 3 or more.... The MAF I think... MarcW - Tuesday, 19 June, 2012, at 2:17:18 pm |

Hello, I disconnected the MAF again but this time I reseted the ECU by disconnecting the battery, there is a huge difference in how the car runs, it still runs very rough and rmp's go up and down but now I was able to actually drive the car and rev it to 3.5k rmp without the car shutting off, there was a bit of backfire through the intake but only a couple of times whether with the MAF plugged it would do it every time I accelerated. So yeah there is a very noticeable difference between the mas being plugged and unplugged. Seems like the K&N did in fact kill the MAF. I'll have un update once I change the part, I already bought the new one and it should get to me in about 5 days, thanks everyone for your help ! it is greatly appreciated

Did you thoroughly check the oil filler tube, as MW suggested? And the oil cap? *NM* Laz - Friday, 22 June, 2012, at 6:15:38 pm |
02s have a dipstick tube that ought to be checked, too, right? *NM* Laz - Friday, 22 June, 2012, at 10:04:13 pm |

The Boxster engine air intake is at a particularly dirty location and to add insult to injury... MarcW - Sunday, 24 June, 2012, at 10:49:46 pm |
