My Engine Just Dies


Recommended Posts

Hi All,

Just took my 2001 996 Cab for a little ride after not driving it for a month. As I was passing a truck on the freeway I bumped the rev limiter and all of a sudden the PSM light came on. Then as I rolled off the offramp the car kept dying every time the engine speed settled back to idle. I was able to make it back home by continually restarting the car when it died. As I approached the house the "Check Engine" light came on. Anyone have some insight on my situation? Will it reset itself?

Thanks in advance for any assistance.

If you live in the USA, Look for your local Auto Parts store, they usually have an ODBII scanner that they can hook up to your car and they will give you the error code for free. I know Autozone will scan ODB II cars for free.

My bet is that you didn't actually hit the limiter, but that your mass air flow sensor is going out or is already gone. When mine went out (the K&N air intake finally did it in), I was accelerating when I had a momentary loss of power that felt like a limiter kicking in prematurely (I was at about 5-6k rpm). All was fine 'till I coasted to a stop, where the revs dipped to the point where the car stalled. It did this at every stoplight until I got home. Autozone reader showed a code indicating a mass air flow sensor problem. Several attempts at cleaning the sensor with electrical contact cleaner, and replacement of the stock airbox didn't eliminate the CEL, so I sprang for a new sensor and all has been well since. Let us know what you find out. Scott.

my little AUDI S3 used to show the same problems after fitting K&N filter

i cleaned it in pharma grade benzine which leaves no residue,, this fixed mine up for a few months b4 it eventually died permanently

Take the whole assmbly out, dont take out just the sensor as you will screw up the alignment of it, i suspect its exacly the same assembly as the AUDI and VW uses.

Hi Guys,

It was the Mass Air Flow Sensor! The car did show any indication that it was going bad and so when it did it put the car in safe mode and was giving the engine more fuel than it needed. Due to lack of time I had the dealer fix and now I'm back on the road.

Thanks All!
