Welcome to the Werkz. Someone here will be able to give you some more specific help.

One way to check your MAF is to simply disconnect it and see if the performance of the car changes at all. If it get better then your MAF may be shot, you can sometimes clean them up with Brake Cleaner, but remove it from the car before you so that.
How long has the engine light been on for? Are there any performance issues with the car? The injectors could be clogged, dirty fuel filter reducing fuel rail pressure, blocked air filter, stuffed O2 sensors.
Good luck

P0111 is the code for the intake air temperature circuit soy you did get that right at the very least. Have any other codes popped up like P1188 or P1189? Have you suffered from any misfires? On another note I'd like to say California's emission laws SUCK.

replaced the intake air temp sensor.. and the engine light still comes on..

Question, after you replaced the intake air temp sensor, did you have the CEL cleared? You have to actually have the code cleared.......

... how do i rmove the maf and perform test to find out?

[brettski]

Not sure on your model, but on mine it was a simple 3 pin wiring connector that disconnects from the MAF body. The Engine Management goes into a default mode because its got no feedback and hopefully will give you something to work with. Good luck.
