The engine cuts out every so often. It cuts out or sputters when I'm driving in town or if I have four people in the car. It does not cut when I am on the highway. I drive it alot sometimes I take 2 hour trips. I don't want it to die on me far away from home! I have a check engine light on. The reason why it's on is it says the Catilitic converter needs to be replaced. But everyone that I talk to says they don't think the cat is the reason. I have done all of these things cleaned the throttle body, replaced ignition coils, spark plugs, spark plug wires, Had Toyota fuel injection cleaning, used Toyota fuel additive cleaner, checked fuel injector plugs with an injector plug tool, (Have not tested or replaced injectors) I have done a compresion test and compresion was good. I have not replaced the fuel pump and I was told that if I want to replace the fuel filter it is in the gas tank with or on the fuel pump. This car does not have a mass air flow sensor. I don't know what else I should do. Hopefuly someone has had this problem and figured it out. I will take any advice. Thank you!
