What is a egr valve
I have changed pretty much everything my truck
won't stay running ive changed distributor cap ac
comPressor spark plugs starter fuel pump spark
plug cords fuel filter and still it only ran for about
15 minutes shut off even after I let cool it starts
then shut off as if I have no gas, it has gas. I just
put like 30. 00 total since yesterday after changing
ac compressor. What's wrong?
did you check the coils or modules. what about fuel pressure. fuel filter. does it stall just idleing or when driving. uf driving it could the egr valve. (exhaust gas recirculator) not operating as it should by staying open when driving. have you checked idle air control. any other vacumm leaks. could be a new part that is already bad you have replaced. anywho throwing parts at it wont solve your peoblem as ot could be anything but diagnosing it properly might be your best bet.
Possible Ignition Control Module. Heat from the engine can affect this once they start breaking down. This can be tested at Auto Zone if you take it out. If the EGR valve was bad you would notice a hesitation when stepping on the gas pedal. When the engine is warmed up and dies on you check for spark out of the coil, it should be white in color, not a orange yellow in color.
