Hi I have an 06 VZ commodore alloytec sedan with 52000ks on it. The last few days it has been shuddering on startup for about 10 seconds then runs normally. Also since it started that i have noticed a significant lack of power. I did a search but nothing came up that helped. Anyone got any ideas?
Could be a faulty MAF give it a clean or swap it over for another one and see if it makes any difference
It was serviced about 2000ks ago. I do it every 5000ks. Maybe fuel filter blocked? Only take about 5 mins so ill change fuel and oil filter and see if it makes any difference.
