Volvo 760 Turbo running rough
Hi you guys I'm new to these forums and have a major problem on my hands.
2 nights ago I purchased a 1987 Volvo 760 (B230FT). I was driving it under hard full boost when I heard a popping then the car lost alot of power and only felt like it was maybe hitting on 2 or 3 cyclinders. I got it home popped the hood and started checking for fuel spark and air. I still get spark on all cyclinders. Looks like some air hoses popped off under such boost so I plugged them back in and clamped them. Then I started checking for fuel. I seems when I unplug injectors 1 and 3 with the car running nothing happens, but 2 and 4 the car stalled. Please help I am new to Volvos and don't know too much about them. There is also not a whole lot of information on how the lh-jetronic fuel system works. I need to know whether it pulses through the injectors or is open all the time. I also want to know the correct voltage through the injector connector harness. All injector connectors off the harness had a constant voltage of 12v.
Thanks you guys
