Shuddering ( hunting ) on start
I am not a man who knows a great deal about cars, but I am learning fast
I have a GT in red on an 05 plate 1.9 JTD
On start at present in the glorious UK july heat, the car ticks over perfectly, then after 10 seconds the engine starts to shudder (hunting as per the mechanic) quite fast and a lot, which in terms causes a huge racket, and shakes the steering wheel. This last for anything up to 2 minutes if left idle.
The problem is resolved as soon as the accelerator is pushed down to 2000 revs, and thereafter the drive is fine and no other issues.
The mechanic says to me if it was my car, I wouldn't worry about it, but how can I get in the car, and let it shudder (hunt) whilst idle, there must be something wrong?
I ran rede through it with new diesel but no joy! My friends friend is a mechanic also, and he says it could could be the glow plugs, even though everyone says these diesel do not necessarily affect the cars performance, he says if running on bad plugs, the cylinders may not fire properly on idle?
Any thoughts, or anybody here of this before when car is started and sat idle?
