Montreal Ignition Issues
I got a Montreal with my father from New Jersey (we live in SE Connecticut) We made a day out of picking it up as it was in great condition and the weather looked good. So we get down to NJ and the car is amazing. Ran to the DMV to get the temp plate. We signed the papers and off we went, two hours home.
Not so easy. On the way onto the NJ Turnpike i saw (in the assist car) the car go through the "EZPass" Then accelerate away. I could hear it, then it slowed then nothing... My pops and brother coasted to an off ramp with a huge breakdown lane and said "we lost power then the engine died"
So knowing nothing about these cars we pop open the hood, then called the two truck. A couple hundered dollars later at 1am we had the car at home. I went through the manual and convinced myself that it was the computers. The first went then the second... Explains the loss of half the engine then total loss of ignition. So I traced everthing back and forth and back and forth and eliminated the coils and the wiring and everything but the computers. It must be them!!!
So i did a little research and thought that I could throw in two MSD 5 units in place of the computers. So we got some used units and got half the engine to run... The used MSD was bad. So got two brand new MSD 5 units with new MSD coils and put it all together and the car started and idles OK but doesn't like to rev. So we switched the coils, the points etc etc. every combo. We checked the wires, checked the cap everything. If we switch the points and the coils you get the same thing, if you switch one you get the engine firing then kicking backwards a bit.
MSD 5's are wired as such, white wire to the points, orange to the coil neg and red to coil pos. i have power coming from the old computer power (middle wire of the plug into the computer) one for each unit. Each MSD sparks when the white points wire is grounded.
When i throw the timing light on i see a line at the top of the little circle. As it revs it hits a wall at about 1500 then can with trouble get through it then sorta have an enemic upper RPM rev then sorta die on the way down.
So the car was running when we towed it here. Are the flyweights in the distro locked up? It was running... Remember. Are the MSD units interfering with eachother?
Does anyone have a clue what I have done wrong.

Dean
