Default Mass Air Flow or O2 Sensor ?

2001 Neon, Automatic, almost stalls for the first few seconds after accelerating from idle. And it only happens after vehicle has been running for about 10 mins or so. Also feels as though the car is missing slightly on one cylinder when at city/highway speed. Both problems are most likely the same source. My guess is the Mass Air Flow Sensor or O2 sensor. Any ideas?
How does one find the sensor on this car?

neons dont have mass air sensors, map sensors though....... if a check engine light is kicked on then go get it scanned, will save u alot of money in the long run.

+1. Except he doesnt have to go anywhere to find out what CEL code he has, just turn the key ON-OFF-ON-OFF-ON and your odometer will display the code followed by dONE.

Yep, just leave it in the "ON" position on the 3rd turn and watch the digital odometer for codes as he said.

I don't know of any Mopars having mass air.

Unless the Check Engine light is on, I'd say the O2 sensors are good.

To the OP, are you just guessing? If you're just guessing and replacing parts it's going to cost you a lot more in the long run. Vehicles 96-newer support OBD-II which gives you a trouble code when something is wrong. Get the code(s) read and look them up at http://www.obd-codes.com or post back here. AutoZone reads codes for free (but I wouldn't necessarily take their advice on what part to buy!).

i had the same problem on mine. couldnt figure it out. no codes or anything like that. took it to dodge and their scan said it was the plug wires were bad. check those. when i had my problem it didnt happen every day. sometimes a whole week would go by before the bogging would start. and dont get the cheap*** wires from an auto part store. get at least the oe replacements from dodge or aperformance set.
