Boost is rough sometimes

Hi Lads.

Another few questions. :hammerhead:

I think i bought the mystery machine LOL :multijump:

Today i put 30 quid worth of e5 in my tank, for last week or so ive been using normal 95 octane petrol and its been smooth. just couldnt get to a maxol..

I drove approx 50 km after putting the e5 in. I was in second gear coming out of a t junction and put my foot down the car chugged and cel light came on. I let off the pedel and stepped on it and the boost was rough more like a

chugging feeling ( cel light went off). this was from 2nd, 3rd and 4th. coming to the end of my journey it felt like the engine was holding back or that it wasnt boosting fully but it was smoother.

Is it that my cars mapped for 95 octane? or maybe a vacum problem? or both.

Before this happened i was driving like a granny as it was icey so i was using higher gears with lower revs.

Ive also noticed when i stop using boost i hear a click noise coming from the boot somewhere, someone told me that it could be the fuel pump turning down or switching off, ( this happens all the time)

Cheers
 
Suspect a fuel pump problem if you hear that noise from the behind you.

Also it wouldnt matter if your car is mapped for 95 and you use E5.
