DieselDude,
Since my car still fairly new with me, I had another observation...If I PREHEAT(it seems set at a certain time) the car 3 times then it starts right away...if preheated once it takes a few revolutions of the starter to get the engine going...it scares me I might burn the starter, so now I just pre heat it 3x all the time. Its the same even if the engine is already warmed up. Would you think changing glowplugs would help improve the starting up?
