Good day good people. Hoping someone can assist with a weird problem.
Driving a 1984 Opel Rekord 2.0 (4 Cyl)
The car is currently running on only 3 Cyl. Replaced the plugs, and replaced the plug leads. Problem persists. Through some troubleshooting, I have determined that number 4 Cyl is the offending one.
Funny thing is, when I pull the number 4 plug lead half way off the plug, it starts running right. Tested this with different plugs, and different leads.
Any ideas on what the cause may be?
