trouble accelerating.

here's a cunundrum. car worked fine till i attemted to pull the engine and broke the vacuum lines. i've replaced the lines and now it starts idles slightly rough in park, idles fine in drive, maybe a little low on the rpm, accelerates slowely aok, but the second the turbo kicks in it sputters, chokes, and the exsaust spits out a cloud of black smoke. i'm figuring on doing a full engine rebuild now anyways but i was kind of hoping someone could shed some light on this issue and what it may be. i figured it was a vacuum leak but i can't pin point one anywhere on the new system.

Black smoke is generally a fuel problem with the car running too rich. Sometimes with carb cars the carb is flooding becasue the needle is not seating or the float is saturated or the choke may not be coming off.

I'd suggest going over the vacuum lines you repaired and make sure they are properly connected. I'm not aware if you have a carb or throttle body fuel injection. If fuel injection, be sure you have proper vacuum to the MAP sensor.
For more help, tell us more information about your car and the fuel system.

it's fuel injected. I'll still be pulling the engine so i will have plenty of time to go over the vacuum lines again.

Been thinking now... is it possible that the vacuum lines have a proper sequence? it may be that i havent put them in that arrangement. are there diagrams out there that may assist with that? i had to figure out by accident when i changed the spark wires and plugs that there was a certain firing sequence to be followed. thing wasn't running on all 4 pistons for 20 minutes till i checked it out... didn't actually find the diagram on the hood with directions till much much later... there are days where i think to myself, "maybe i shouldn't aspire to be a mechanic...."

Yes, there are typically diagrams in the service mauals showing all the vacuum line connections. What year/model/engine ? (86? or 87? 2.2l Turbo?) I will check if I have a manual that covers your car and shows the vacuum routing.

the engine is from the 87 dodge 600. 2.2l turbo. thanks for looking into this for me.
