Before I tell you, could you please explain why you would want to do that?

Car stalls. it will run for a while then stall and wont start it just cranks after about 5 min it will start again. first i had 2 codes come up maf and crankshaft sensor. Then I cleared the codes and ran it in my driveway and it stalled. Then i had 3 codes come up Maf crank and cam position sensor. thinking maybe the ecm is bad. I am replacing the maf as soon as it gets here (had to order it)

Sounds like a bad crankshaft rotation sensor. These tend to develop temperature sensitivity when they start to go bad. Next time it stalls and will not start, check for spark and the smell of fuel at the exhaust. A bad rotation sensor will shut off both. The MAF may have problems, but I've never experienced a bad MAF keeping the engine from starting.

Ok got the car to stall have no spark like you said. Next question would a bad crank rotation sensor cause the car to throw other codes? Besides the crank code i get the maf which i just put a new one on, camshaft position and iat sensor codes. Just asking because the crankshaft sensor is a pain to get at. Thanks for your help.

Did you clear the codes after you installed the MAF? Codes don't clear themselves, you have to clear them with the scanner.

More than likely your problem is the crank sensor if there is no spark and it gave the crank sensor code.

If you replaced the MAF and you're still getting MAF codes, then look for an intake leak, like a split in the intake rubber. Or you might have a cracked intake manifold.

Change the crank sensor, see if the MAF sensor problem goes away. Let us know what happens.

took it all apart this evening. Figured i would change the timing belt since it is apart. good thing too as the old belt was missing some teeth. when I took the bottom cover off all the pieces fell out.. I am changing the sensor in the morning, the parts store had to order one. Maybe some junk off the timing belt was interfering with the sensor.
