I've been getting the increased emissions warning off and on and then this weekend it stalled when backing up. On the way to work today; once the car was warmed up it started to die when I pressed on the gas and then engaged, like it was starved for fuel. On the way home it did it again but worse. Twice it stalled, a couple of times rev'd up then engaged and all the while the tac was all over the board. I have an appointment with the dealer on Wed. morning but I'm out of warranty. God I hope it's not anything big. Thoughts?

Could be any number of things from as simple as bad gas, to o2 sensor or cat. How many miles are on the car? Did you pull any OBD2 codes to get specific error messages?

I'm sure the dealer will figure it out quickly. If it got to the point of stalling the car, defintily not something you would want to put off any longer.

Thanks for the reply. Only use premium, 68K on the car. I'll look into searching the codes.

Pressure regulating valves. One on each valve cover. Very easy to change. Will run you about 30$ each at the dealer.

Happened to me once, it could just be faulty fuel pump with the high pressure failing. Good luck and keep us updated

Or filthy fuel injectors. Could be a number of things.
