Some weeks back I posted here for some help with the running of my car.
Since owning the car I have done a massive array of work, and up till recently the car was running really well.
Basically on doing about 100 miles on the motorway, the loss of power returned, I have already changed the Coil packs, plugs, full oil service, air filter, fuel filter etc. The problem now seems to be more noticeable when in the lower band of revs, from 1800 to 2300 rpm.the car sometimes will suddenly jolt, loose power then sometimes putting down more gas will then make things go normal.up until the other day this was only very slight, then it went really bad. Couldnt get past 50 Mph in 5th gear, changed down, could go alittle quicker.
My firtst thought is that the fuel might be the issue or crap in the tank, when this happened I had 2/3 of a tank if Asda fuel, maybe it will run better on a more expensive fuel? I also havent cleaned the EGR yet? Will it be worth doing this?
One thing I did find is on the way back from work the problem had 99% disappeared and only felt it very slightly when doing 40 Mph in 5th.
any help is appreciated.
