Hey all. Out in Death Valley this morning. Did 45-miles of dusty washboard road. Pulled onto the Tarmac and pretty much right away had a power loss. I think this is the limp mode. You can feel it turn on. Pulled over and inspected the easiest culprit. Air filter pretty dirty. Knocked quite a bit of dust out but nothing really crazy. Continue with what felt like more power but then again into limp mode and check engine light. Made it to auto zone in. Pahrumph NV, bought a filter, replaced and rolled on. Was fine around town then climbing out back to the limp. Back to auto zone and they pulled a P1557 code. Reading around a little I thought the MAF might have gotten toasted by the dust. A really slight super fine layer made it past the filter upon closer inspection. I read about folks blowing MAFs from dust so that was my first thought. I could drive the 30-min to Vegas and buy a MAF if it's a likely culprit.
The only other possible symptom is there may be a slight change in the turbo noise. You rev it, get the normal whistle, revs fall to idle and then a second or two later you hear a little whistle like some pressure is bleeding off. I have a new PVC valve and vac lines. Intake all inspected during a recent timing belt job. Thoughts?
We are from Oakland and headed back there hopefully. Safe to drive? Also any good shops in Vegas or between Vegas and home? As much as possible I do my own work and have a wholesale hookup on parts so making it home safely would be ideal. Leaving my phone if anyone has any bright ideas but I'll check here also. Thanks a million. Matt 650-504-8800
