Ok so when i first start my van i get a lot of grey smoke and it drives a bit lumpy for about a minute then the smoke goes away and it drives normally.
The smoke is coming out of the exhaust and out of the flex part below the engine also
Secondly sometimes (usually accelerating to or at 50/60mph) i get the yellow coil light and the power cuts, i can just turn off and back on the engine and it works again but with reduced power (wont rev past 3k ish).
are these two issues linked? I CANT read any codes as i have tried 4 different code readers in the obd port (physical reader, direct to laptop, direct to tablet and bluetooth) and nothing can connect.
What should i start replacing to remedy this? Full oil and oil filter, air filter change all done recently.
I have the fuel filter to do this weekend.
Glow plugs are pretty cheap so i was thinking of doing these next
