For quite some time now I've discovered a few trembling of the engine when first starting it in the morning. Sometimes they appear even during the day, after the engine was stopped for 2-3 hours.
Gear is in P, I start the engine and after 3-4 seconds I get 4-5 flickers from the engine, every 2-3 seconds. It seems like it's running in 3 glow plugs or 3 injector for 1/10 second, I don't know.
Injectors and glow plugs were checked 2 months ago with Tech2, all seemed to work very good. I already did the 3rd injector wiring back in November. Could it be from the other 3 wirings?
Any ideas will be appreciated.
