- VE Sv6 Commodore 2010
Hi all - apologies if this exact issue has been posted elsewhere, I had a look around but couldn't find an exact solution it seems.
I'm living in Brisbane, and I've owned an SV6 VE Auto 6-speed since I was on my P's (early 2013, bought it at 80,000km). It's now at 217,500km, and for the last 10k I've noticed a small issue develop with my car misfiring at low revs. I would say it's around <2,200rpm? It's at the point where I can barely go up an incline or put load on the engine in a low rev range without the car shaking noticeably.
While on a trip to Yeppoon, I took it to the Tyre & Mechanical Shop up there since I didn't want to drive home with this issue. After a diagnostics test, it showed a Cylinder 3 misfire, and they were bringing up topics such as replacing rings or valves. The next day, they said that it was just a loose breather hose which they'd put back on, and that was all the issue was.
It ran fine for the majority of the trip, handling a few overtakes no worries, but when I got back to Brisbane (7-8 hours of driving), the same issue arose again.
A few more weeks and I took it to a mechanic here, who got the same code from a test (cylinder 3 miss), and did a check of all the air intake/hoses which, upon getting my car back, made no difference. This was just yesterday.
Admittedly my service history isn't great, there's been a few times where the car has probably gone around 25k-30k without an oil & oil filter change. Have always used 5W-30 Synthetic.
The conversation today with my mechanic was about maybe dodgy spark plugs or even a timing chain issue ($$$), but it seems strange that while in Yeppoon the mechanics there seemed to resolve the issue perfectly at the time. Any suggestions?
