It sounds like your air mixture blend door is not operating properly. This is causing the cold air to have warm air meant for the heater to mix in with the cold air.

Why will it run with the vacume line off the map sencor


If the engine management system is working, the engine should stay running but perhaps run rough because pulling the vacuum line off tells the computer to really richen up the mixture.

Had no spark. Replaced ignition mod, 2 coil packs, and computer. I now have fire; problem is engine will not run, the fuel injector sprays fuel (too much i think). When i unplug the injector the engine...


Check for any wiring pinch which might have occurred when the injector was replaced. The injector is driven directly by the computer, so it seems to point at the new computer as being faulty. (pulse signal is always 'on')

Engine swopping


I can't give you direct knowledge, from having personally done this swap before, but I can offer you that the 1990 Cavalier, did have a V6 as an option.
The 3.1 Liter V6 with MultiFuel Injection System.

Of course, you're going to need the ECM, (Computer), and the complete engine wiring harness also.
