HELP

 

have you checked the plenum gasket? a bad plenum gasket could clog your cat and cause other problems. the easiest way to see if the plenum gasket is to take the air filter off and look down the throttle body for oil.

 

it is wet down inside the intake looking down the throttle body

 

the plenum gasket is most likely blown. it happens to pretty much every magnum engine eventually unless someone has replaced it with a Hughes PLENUM REPAIR KIT or something similar. i don't even really get the point of having a plate bolted to the bottom of the intake.

 

yes have a93 dakota to trade parts with have done alot of work to this truck changed ecm last night test run to come

 

changed the computer and map sensor from 93 dakota also cleared partially clogged vac. port on intake it ran perfect today went 50 miles no problems but i need to figure out which of the three things actually cured it . i have seen alot of the same issues in this forum i hope it helps others.

 

found problem dirty connector at map sensor remember SIMPLE SOLLUTIONS FIRST remove and spray with contact cleaner all connections especially sensors

 

wrong again im aparts changer troubleshooter and guess what it was a bad pcm from advanced auto they reurned the part fur a new one the first one was wrong it for high altitudes truck runs perfect again.
