I have a 1995 Dodge Ram 1500 5.2l when I start this vehicle it runs rough until it get to operating temperature, then it runs fine. I have changed every sensor and problem still presist. Also changed plugs and wires, distributor cap and rotor and nothing has seem to make a difference. HELP!
is there a way to reset air/fuel mix when cold. runs like its flooding when cold til it hits 95 deg,then cleans out .after that its fineis there a way to reset air/fuel mix when cold. runs like its flooding when cold til it hits 95 deg,then cleans out .after that its fine

run the fault codes and look for problem MAF/Vaf sensors and ambient temperature sensors not closing down the fuel rich circuit in the ECM until you upset the input by the pedal movement
Have you checked for a broken valve spring. Repaired a dodge engine with the same running issue as you have described and it was a broken intake valve spring.
Sounds like you've done everything but the injectors. Run a bottle of fuel injector cleaner in a tank full of gas every time you do an oil change after this time. Also, check the fuel pressure to see if it's where should be for the injectors. But then, if it has enough pressure to go through the dirty injectors to make it run, pressure should be good. Check it anyway.
likely your throttle position sensor or idle air control valve. Try disconnecting each one when the problem starts if it corrects you have found the culprit.
Your electronics won't work properly if voltage is low. Charge and load test battery to make sure it's good, then check charging system to make sure it's operating. Once that's squared away you can diagnose running problem if it is still there.
yes I have changed all those sensors and still the problem persist.
