96 Dakota 3.9L stalls when cold?

Question

If I go two short blocks(this has a manual trans.so with a little two stepping on the gas I can keep it running) everything is usually ok. No codes are present but I've monitored the IAC and coolant sensor on cold start and things seem normal (new IAC installed). All summer things were ok. I've heard that carbon can cause cold start and driveability issues so I've put Chevron Techron in the gas (haven't used the full tank yet) and it feels like it is running better but then again it always ran fine hot and gets good fuel mileage.Before this problem started this thing never ran at high idle for more than a few seconds on a cold start no matter how cold it was. This is not a big deal but the stalling has made my remote start kinda useless. Any body have any experience with such a problem your help would greatly appreciated. Dave

Answer 1

some times the oxygen sensor will not set a code but will be getting bad..you can do one of 2 things here...the 02 sensor can be cleaned...pull it out and use carb cleaner to clean out the carbon in it. if this helps...I would suggest replacing the 02 sensor.

Could also be the EGR valve...as this will not set a code either...the EGR selinoid will set a code...but a bad EGR valve itself will not.

Hope this helps.

Answer 2

a botle or 2 of a gas therapy replace gas clear out song up dont relay on a code decrease you run tank greater trash or water types greater so in wintry climate months some human beings like my self by no potential run under a a million/4 tank i attempt to maintain it 0.5 finished to finished you upload a gas therapy each and every few months to maintain equipment clean and water loose

Answer 3

the IAC port can be dirty and cause a runability problem but you will see this more when its warm not cold. also check for vacuum leaks around the intake, they wont set codes but will cause a cold start/runablitly problem. other than that you have covered your basis correctly
