95 awd safari van running rich & when going up hill & accelerating hard to keep speed it suddenly loses power. At idle it runs extremely rough & rpm's flunctuate as if it was going to stop kill.
Could this be a fuel pump, catalytic converter or vaccuum line issue? Please advise.
Your egr valve might be faulty bring it in to the auto parts to have it check out what your looking for is the 32 code on the OBD II scanner.
Do you have a check engine light on? Is this a 4.3 with central port injection? If it's running real rich it might have a fuel leak inside the intake, either a fuel pressure regulator leaking or a feed line to the injector.

Is this 4.3L port fuel injection or a throttle body injection that looks like a old style carb ontop with round air filter housing?
