Was advertised as running fine but only off road use but had an mot , we went to view it and drove it briefly as seemed to be stuck in low ratio , so only around a carpark . we then had it delivered . On its first drive seemed to be rough and bogging down with acceleration , rev at standstill seemed to be ok was just in gear and under throttle .
so what I have learnt from you and other forums is ....!!! learn how to check things rather than just go out and buy new !!!!
We purchased :
new maf sensor
petrol temp sensor
leads
plugs
rotor arm
distributer cap
whole new distributer
timing adjusted numerous times ....
compression tested all ways possible ....
The fault ....... 2 injectors blocked ... removed them all cleaned them through with carb cleaner , cleaned plenum , cleaned idler , and put it all back together .
ran much better , smoother , cleaner . I do feel that maybe might need a tune for air / petrol etc as I moved / adjusted everything I could think of with a large hammer .
We had a swb 3.9 efi a while back with a 5 speed gearbox , it went really well and very attentive with throttle to the floor . Maybe this one being an auto just makes it a bit less attentive !? , but seems to be running fine with all my new parts !!! .
So before you start spending a small fortune on new bits ... test properly the bits you have !!!!! .... lesson learnt .
cheers
