My 1989 740 Turbo has been running erratically for a bit of time now and it has really stumped me.
When I first start the car, when it cranks over, instead of a uniform dun-dun-dun starting noise, the engine makes a dun-dun-dah noise as if it does not make compression in one cylinder.
After it starts, it runs erratically accompanied with a small ticking noise. Then, suddenly, the noise goes away and the car runs perfectly smooth.
After that, if I were to start the engine again right after turning it off, the engine makes a uniform dun-dun-dun cranking noise before it starts.
The injectors, spark plugs, and the distributor are all new.
What could cause this problem? Any help is appreciated. Thanks.
