Default Gets warm, then dies. (fixed)

I'll start the car and it runs fine for about 5 minutes. When the rpm'* slow to a normal running speed the car starts to spit and sputter then eventually dies. I've checked the ignition coil, replaced the fuel pressure regulator, the o2 sensor and spark plugs. The service light does not come on. It has approximately 240,000 miles on it. Thanks.

Try unplugging the MAF. The car will not like it for a little while, but should smooth out. You will get a SES light, ignore that. If the problem gets better, you have a bad MAF. If no change, then test the fuel pressure.

It'* been a while for the fuel filter. I'll replace that first then check the MAF sensor again.

It was the MAF sensor. Thanks for the help.
