I have a 2014 Nissan Altima with 2.5 engine with 137xxx miles. On a cold start the engine will stall out within 2 to 40 sec's after starting.Once I drive the car and it warms up it's good but if I go and grab something out the store for 5 minutes I'll start the car and it will stall again. The only thing that stops the car from stalling is stepping on the gas to keep the rpm's from falling.I have no check engine lights on.The Rpm's drop then is shuts off.I could be in park or driving down the street. The dealer could not find anything. They did a deep carbon clean of fuel system and engine.They wanted to replace the throttle body but I don't like expensive guess work.Once again, no check engine lights.Any recommendations?
Did they test the fuel pump pressure with a mechanical gauge or replace the fuel filter?? Going to a dealer for even the time of day is a bad mistake. Find an independent mechanic who won't rip you off like the dealership will.
