Took my father in law out for a spin in the lightning over christmas .
Done all the usual checked fluids etc, as its not been used for a few weeks it started up straight away , let it warm up and pootled off to the garage ,fueled her up and off we go down the duel carridgeway, after she was warmed up i see a large gap on the road ahead so i nailed it and not much happened, so backed off and did it again and nothing.
Its fine on tickover runs smooth and sweet even seems to be ok driven normally its just when you hit the gas hard there is what i can best describe as a judder/vibration coming from the engine, its not the type of vibration like there is something loose its like its only running on 5 cylinders or something, i have thought maybe not getting enough fuel, but is it possibly something to do with the blower not being very technically minded on all this modern stuff i dont know if when they play up do they just stop all together, the boost gauge is acting normal,
I tried all sorts and if you back off you seem to be able to almost drive through it and the top end speed seems to be unafected, its just seems to be on hard acceleration that the performance is well down on normal, a bit like if your timing was well out, it has sat outside in the frosts these last few weeks but is all antifreezed up.
Anybody got any ideas as i really could do without starting the new year having to take out a second mortgage to fix me truck
Cheers in advance for any advice with this
Happy new year too you all KEV
