Does anyone have a used MAF they would be willing to donate or sell cheap?
I can paypal shipping costs for anyone willing to donate one.

My Disco has been throwing the P1171 and P1174 codes and from what I have read it seems like its the MAF causing the problem.

I'm strapped on cash right now and can't afford a new one. So anyone able to help me, it would be much appreciated!

 

Thought about a can of MAF cleaner? Only clean when stone cold and don't turn on ignition first to get radio playing, etc. A part inside is heated to 350 degrees plus, so thermal shock can make it from dirt to dead. New air filter? Local junkyard?

 

Already tried cleaning it with CRC MAF cleaner, waited overnight then took it off and cleaned it in the morning and didn't re-install it until much later in the day. No luck :/ Have not replaced the air filter yet but it still looks very clean (no junk in the rib slots) and I have called all the junk yards in my area and no one has a MAF. Every place I called said they don't normally get in much for imported vehicles, which I find ridiculous.

have you tried Paul Grant? maybe he will take pitty on you and cut you a good deal on one if he has it.

 

With just those 2 codes, it is not the MAF and if you were going to spend any money replacing, being strapped for cash, I would suggest you follow the directions in the Rave and test it first.
My money is on a vacuum leak unless you come up with any more codes that would indicate a MAF failing.

 

Thank you everyone for your imput!
Mike- I was thinking it could be a vacuum leak but i have already replaced the upper intake manifold gasked and checked the other gaskets dealing with the vacuum system. I have tested every area in the engine for potential vacuum leaks using carb cleaner, propane, a mechanics stethoscope (with and without prong) even tried the cigar trick. Tried disconecting the fan and testing so there would be no air blowing around as well.
The o2 sensor were all replaced about 3 months ago.
If anyone knows how to interpret fuel trim to the problem, the ong trim bank 1&2 is usually about +19 at idle (very lean?) And short trim is usually around +4 bank 1, while short bank 2 will range from +6 up to +25 at idle.
