any suggestions?
 

I have a 87 Gt with Gt-40 intake, port and polished heads, mac shorties, 2.5" dynomax cat back, E 303 cam, frame connectors, 3:55 rear end
last week i put on BBK fender CAI, and BBK 25" H pipe with high flow cats.

I know the car needs new plugs, wires, cap, rotor, and coil. and i recently clened the injectors, but the car seems to hesitate especially when cold would this be from the old ignition???
I had the MAS out to put the CAI in and i noticed that only one of the wires in it is white should I spray it with electrical cleaner or??
and what would be a good idea for next upgrades? anyone?
