MAF Sensor or other problem?

[jlightle]

Ok.
so my MSP has been running really Lean lately.
so i took it to the shop and they said that my turbo pipes are cracked and they need to be replaced. so one week later i have new pipes and a new cold air intake.. just got it back today and still am having the same problem.. Could this be my MAF Sensor going bad or something else. when i took it to autozone they said i had a Misfire in one of my cylinders.

any thoughts would greatly help on this..

your maf is more than likely perfectly fine this same thing happened to me and I went through hundreds of dollars worth of spark plugs figuring it out... but my bf installed my maf relocation kit (http://www.***************/MAF_Relocation_Kit_p/sumafrl.htm) and we never had a single misfire problem since and its been over a year running the same setup, same plugs at 10psi... you could also just find 2 2.5-2.75" transition couplers and 4 clamps...all u need to do is put the maf closer to the throttle body so it gets a good/correct reading... this is by far the best mod ive done to my car to date...gets over 25mpg and runs very strong and smooth all the way to redline...check it out

So after installing new "hot pipes", New Spark plugs, and a New MAF sensor.. i think i have solved the problem.. and the winner is ........Ignition Coil...

after viewing some videos online of bad Coils i went to my mechanic and asked if this could be the problem.. he said probably not, but i went anyways and bought two new ones for about 60 buck at auto-zone just to try , and bang.. problem fixed...

Needless to say this is the last time i will go to this mechanic.

i have be driving it now for about two months with no problems.. now that i know this was the problem, i will probably upgrade from the auto-zone coils to more performance ones...
