f7p looses power

Post by frazeb » 21 Mar 2012 07:21 pm

i will be driving about say at like 35 in 3rd then the power will die down then i will put my foot down a slight bit or something or even just keep it at the same position and it will come back, when its acting like this the revs sometime drop low while stationary. it doesnt do it all the time but like about 1/5 of the time and it doesnt do it when iv got my foot down. any one got any ideas

injection, probably be a coisedence and it shouldnt really make a difference but its been doing it since i put the slighty more expensive petrol in it

Gonna say it's a temprature sensor issue, either air or water.
