Spent 3 months in portugal recently on the way down through spains mountains engine started to stutter in 4th gear on gradients. Eventually after an hour seemed to clear and ran normally for next 10 weeks but not a lot of mileage done as its a motorhome.
On the run back home 1500 miles in 3 days it progressively got worse to the point it was stuttering about 70% of the time as i was approching home generally on a slight gradient or if engine was working hard.
Mileage is 60k
Any ideas where to start would prefer to do basic checks myself
Thanks
