Gilly and other Gurus Please help -ML not starting

i have a 1999 ML 320 140K miles on it and i live in Michigan (ann arbor area)
i was driving back home last night and suddenly i lost power in the engine i mean even though i press gas its not going up Luckily i was just couple of miles from my house so i was able to get back to my house at 5 miles an hour .
the vehicle is like in idle state even though i press the gas completely.
Suprisingly THERE IS NO CEL light( The light didnt come up)

i got back to my house and shut of the engine . leave it overnight and the next day i started it cranks up but doesnt start i have to turn the key back to shut of cranking.i hope its not the transmission. i did a lot of research on this message board and came up with things like MAF or CPS sensor or the Fuel Filter going bad .
i have changed the MAF a year ago and fuel filter 2 yrs ago. i havent changed the transmission oils yet.
one thing i suspect is i changed my air filter to K&N Oil based filter 6 months back and some one complained that the MAF goes bad for this filter.

i can change the CPS and MAF (Thanks to the forum for the DIY's)
but if it is bigger than that could you please suggest me a garage tha does repair ML's in Ann arbor area in MI
My car is sitting in the Garage... so guys please help me out...



Thanks in advance

When my CPS went out on my 430, it did the continuos cranking thing. No CEL either.

I did not have the driveablitity issue though. When it ran, it ran fine. Only when I tried to start it would the engine just keep cranking all by itself without starting. It would eventually stop cranking after a few seconds.

Research "limp home mode."

I took it to a mechanic shop driving 5 miles/hr and he connected the scanner and it read 2 error code P 161 and p 170
he replaced just the MAF Sensor and everything is fine

Thanks Guys
