first try getting a new MAf burnoff relay and a maf power relay then if that doesnt work you eitehr need a new computer or a new maf sensor to tell ya the truth i think the dam sensor is more than a rebuilt computer check my sig though

THere is a remote chance it could be your TPS is out of adjustment. Or you have an air leak betweet MAF and TB.

If it idles rough disconnect the MAF and see if idle improves.
Step #1
Other wise clear all codes start engine run it above 2000 rpm for 1 min or until SES light comes on. Check codes, hopefully you have a code 34 after that, otherwise it is an intermittent problem.

Then clear the code 34, and then disconnect the MAF sensor, repeat step #1, if you get code 33 the MAF sensor is bad.

Good Luck

Hey all i unpluged my mas and the car died. That means that the sensor is bad. If i am wrong let me know. Thanks

Blueiroc whats the deal on this I am having the SAME PROBLEM. code 34 and unplugging the MAF causes my car to die. Let me know if and how your problem was resolved.

I was pulling a 34 because I had disconnected my MAF and turned the ignition on. the computer then realized it was gone and spit a code. when i turned the car back on, it still thouht it was gone, so i disconnected my battery for 30 sec. and then started it back up and it was fine. This probly doesn't apply here, but i thought i'd add something anyway.

Well i did a test and i got a 33 code so replaced the maf. I have had no problem with the new one. Thanks for the help
