Good evening guys.
Yes the hemi has the electric egr on the front right side head.
removed o2 B1 sensors fire it up
no change.
crank it and strarts revs to 3000 almost, stalls after short attempts to run.
egr is out of the manifold. no vacuum, booster out no vacuum. plug them in. crank it w hand over throttle body, same stuff, revs but lil less. somewhere a big ***** vacuum leak.
remove intake.
split open in back underneath bottom. must've had some back fire in its recent past w new coils and plugs and o2's, and new fuel tank and pump. they gave up trying parts and sent to us. I'm only a tech there a week. Got screwed over by Lexus big time.
Ram needs an intake to start. Customer says will pay 1000. we say no.
It did not even run till I played w it a few hours so far. not a fun truck to wrench as Tom Goldman would know, and many of you others.
can't hear the vacuum leak with the insulation on it and ratty exhaust manifolds.
what a mess. pushed it out, next bring on the patriot with falling out ball joints, lol.......
