i got my car scanned last weekend and he came back saying that my maf is bad? i dont understand all the wires are intact. do these things just burn out out of the blue. and the computer was confused from the msd 6al i have on there. he said it couldnt quite keep up. any thoughts about the maf would be appreciated. and what kind of maf should i go with if i need to replace it?
Thanks Jason

 

What code(s) did you get?

 

i dont know the actual code numbers but the maf and tach wire were messed up

 

I had my car scanned one time and it showed a bad MAF and it turned out to be the POS hypertech power modual that was fuggin up the computer . Nothing was wrong with anything on the car

 

Yes, the MAF can "fail" out of the blue. It can also be a problem with a bent pin in the harness connector, or some cars will damage the pink wire to the harness that supplies +12V from the fuse panel. For starters, take the MAF connector off, turn the key on and see if you have +12V on the pink wire.

Not sure what he is talking about as far as the computer being confused, the MSD "couldnt quite keep up.", and problems with your tach wire. I seriously doubt that the PCM can even tell the MSD is there. Did he possibly get DTC 99, tach output circuit? I've never seen an MSD cause this kind of problems.

 

I had a bad MAF code once, and it was just the connection going to the MAF. I replaced that pigtail connection, and that solved the problem.

 

i dont know about the msd he said that the 3 sparks for every 20 degrees rotation it was confusing the computer and sending the ses light off. any more help will be appreciated.
Thanks Jason

 

I wonder if its because you modified your MAF?

 

There is no problem running the MSD box.... the PCM can handle it fine... mine did for 5 years. There are probably hundreds of members here running MSD 6-series boxes with no problems.

Get the exact code(s).

 

he did say something about me descreening it could of defected it somehow
Thanks Jason

 

Taking the screen out, assuming you didn't damage the sensor elements while you were remiving it, will simply screw up the calibration a little, but not enough to throw a code. It is possible a chunk of something made it past your air filter?

 

maybe i mean i havent cleaned the filter for about 6 months. so maybe i appreciate your help guys keep it coming
Thanks Jason
