rough idle for first 2 minutes until oil is warm.
I have noticed that my idle is really, really, really rough. The entire car is shaking violently until the oil temp gauge reads about 60 C. After that, it seems to idle pretty smoothly. Not perfect, but it is very very tolerable (especially when the idle adjust knob is all the way up). Starting the car is always great, and it starts in less than a second (always).
Is this a symptom of possibly bad glow plugs. I did an electric 12v test and all the glow plugs are getting power. But it could be possible carbon buildup in the pre chamber or one or more of the plugs may have gone bad.
I guess i am trying to see if this is more likely the problem... or i should probably do a compression test as this symptom (really rough until warm) is usually a compression issue?
Just trying to narrow down my possible problems. I don't think it would be the motor mounts as it would probably not nicely level out at a warmer engine? (yes i did a valve adjustment)
could the injectors be causing this?
-Thanks!
