Hey guys, my '92 V6 4x4 is starting to act up when the engine has run for a while. After stopping for a bit, it has a hard time starting. Mostly sputtering and really can't hold an idle. Tapping the throttle does nothing.

Leave it for a few minutes with the hood up. When it cools for 15mins or so, it starts right up and runs just fine. Vapour locking?

The Chilton manual suggest looking for clogged fuel tank vent lines. Any other places to look?

With the weather warming up, this is happening more often and is a royal pain. Also, I worry that it might crap out while driving during the summer with the AC on.

Any help would be appreciated...

PS the truck runs really well otherwise.

 

try seafoaming it. heres a thread.. https://dodgeforum.com/m_835531/tm.htm

 

try running the codes, that will give you better insight as to what's causing the problem (assuming its a sensor issue). At this point, it really could be anything. It could be a vapor lock as you thought, could be a bad engine ground connection, or it could be a bad signal generator switch. Try pulling your codes and let us know what, if anything, comes up.
