Proplem i have a 2002 dodge indrepid when i push gas pedal it dosent whant to go ive changed all 4 o2 sensors a fuel pump and it still does it.i dont know what to do.

Speed sensor , oil sensor , cam sensor

change your fuel pump relay.

presure sensor evap

Fuel Pump and fuel filter change sounds to be what the Dr ordered also change the fuel pressure regulator all at the same time. You will be 100%

code #0406 = egr position sensor circuit high ( stuck egr valve or bad egr sensor most likely sensor )

code #2096 = downstream fuel trim system lean ( see next code )

code #0137 = O2 sensor bank 1 sensor 2 circuit low ( replace rear O2 sensor driver side )

code #2299 = brake peddle position/accelerator pedal position incompatible. ( hav you been power braking this truck? ) ( brake light was on wile accelerator was being pushed )

MULTIPLE MISFIRE CAN BE CAUSED BY.CLOGGED FUEL INJECTORS.ADD A CAN OF SEAFOAM TO A 3/4 TO FULL TANK OF GAS.CHANGE FUEL FILTER, IF ALL READY CHANGED SPARK PLUGS AND WIRES.A WEAK FUEL PUMP AND A CONTAMINATED MASS AIR FLOW SENSOR WILL CAUSE LEAN MISFIRE CONDITIONS.

I don't think it is your O2 sensor especially from the catylatic, because you mention smelling like gas and presence of gasoline. "Plugs" hopefully referal to the spark plugs, try to trace where you see gasoline and where it is coming strongest from. This is a case of leaked fuel line, fuel rails, fuel injectors.
1) Trace the source of where it is wet, there maybe a leak somewhere and you car is not getting the amount of fuel pressure to combust and thus make the engine dies. 2) Check your fuel injectors, fuel line rail, could be leaking or become loosen and is spraying gas when the fuel line is pressured into the spark plug socket. 3) You may have a dead spark plug one or more, and isn't combusting the gasoline, thus creating no compression leading to engine dying. 4) Leaking head gasket. Best is tracing where the gas is spewing from. That should help.

it may be your throttle position sensor (TPS) or you may need new fuel injectors

Replace the mass air flow meter.Sounds like your problem.

I have a 97 gmc sierra .This truck is the same as the chevy ok.Its a 350 5.7 liter 4x4 Z71.I took it to auto zone which was my first mistake.They put it the scanner and said bad O2 sensor.Ok so which one is it i said.They dont know.Well there four (4) O2 sensors in this truck i hope you know that.I had to replace all four of them before i had to take it to a real shop.It seems the fuel pump i replaced a week earlier with an auto zone fuel pump was bad.Ive changed my feul pump 4 times now and have 235000 miles on still running.You need to get your fuel pressure checked.It should be 65 psi to start it and 55 psi to run it.If the pressures are good it could be a different O2 sensor or maybe the mass air flow senor.My last option would be the fuel pressure regulator because it seems to be a waste of time and money.I would get that fuel pressue checked first.Good luck.
