RUNNING ON 3 OF 6 CYLINDERS 900 1992

Symptoms:
1) The engine continues to fire on Cyl #1, #3, #5 ONLY
2) Fuel is going to all 6 cylinders
3) Replaced both Power Stages with new ones
4) Replaced front knock sensor

Any ideas???

I replaced the front sensor and the code will not clear. I suspected wiring, but cannot find a fault. Checked all grounds; I know they can play havoc with Volvo's. This problem did not exist before I replaced the head gasket.

Please post as soon as possible...I hate driving the company truck, but happy to have a ride.

Thank you!
Greg
