Slight problem again guys......
Since getting the car 10 weeks ago the performance seems to be getting worse. I've done 3000 miles since then and lately i've noticed that flooring it makes very little difference to the speed i'm doing.
The first couple of days were brilliant - i could tap the accelerator while doing 80 and it would shoot off - now it struggles to reach 40 without me literally having to put the foot to the floor.
I've done an oil and filter change using GM spec 5W30 and obviously the plug change. I also filled up with V-power for the first time last week.
Is there anything you guys can suggest to get it back to it's peak performance as i'm quite upset at how under-powered it seems........
