Question about Cars & Trucks
If you barely push the throttle and it's sputters, try unplugging the EGR valve and see how it runs.Make sure you have vacuum to the EGR valve.Start engine and on the outside see if you can put your finger under the EGR valve and see if it sucks up. Be careful and not let the engine get to hot when you do this test.

Depends how long since your last tune up and mileage. I would do a normal oil change, oil filter, air filter and plugs. If she still does it, try checking for a vacuum leak. Start the vehicle and spray "lightly" carb cleaner around your vacuum lines. If you have a leak the engine will increase in idle suddenly. Replace the line or part. AS A LAST resort and pretty rare is the distibutor. They usually run about 75.00 to 110.00...hope this helps.

Those are cylinder misfire codes. PO300 is random misfires (meaning 1+ cylinders misfired) and the other 2 codes are for cylinder #1 and 2. Did you change the ignition coils yet on 1 and 2?
Do you let the tank go to empty before refueling a lot?

The ECU controls all of that. When they start to go bad they do very strange things that are hard to diagnose. They run about $300 bucks of you do it yourself. They are simple to do. Shop around because it is an electrical component and many places wont warranty them but some places do if your lucky you can find one. I also would not rule out your timing or distributor. I dont know you or what you have checked but could be the rotor or could be carbon tracking inside the distributor. Even the slightest crack in the cap can mess everthing up.
