My son has a 2001 elantra, we had it read on a code machine so many codes came up, they didn't know what to check. The car will start and idle for 2- 3 minutes that it just stops. We changes the oxygen sensor,idle air control valve, the maf sensor and the throttle pos. sensor. We checked the pressure on the fuel pump and that is good to. my question is where do I go from here

Check your egr valve it may be sticking or clogged by carbon can remove and clean with a carb cleaner aslo check operation of valve that it moves and not stuck with the cat converter start vehicle and put hand by exhaust give a little gas if it feels like hardly any pressure ur cat is clogging a clogged cat conv will set off multi sensors so will an erg valve
sorry ur right on no egr thinking of different engine-- when u rescan vehicle if there are any codes go to this site www.obd-codes.com and then click under the blue and green header "trouble codes" this is a free site for reading almost all trouble codes the highlighted blue codes advise on what problem and what to do to fix and if other codes can be affected
Did you disconect the battery if not disconect the battery wait 1 or 2 min and re connect the battery if all the codes come up again even the sensors you repaaced (change the computer it,s bad)
