you need to take into account that if the autobox is electronic then each time the car changes gear a signal is sent to the engine ecu to cut throttle while changing gears ? (just a thought)

i had this problem on a Renault megane and i changed everything springs top mounts shocks the full shooting match and it still was their (mainly when you dry steer )but it turns out to be shocker top mounts due to after market copy parts it will never be cured unless you put original parts on but the owner decided to live with it in the end as it did not affect the m.o.t also this problem is recognized by the dealership and part manufacturers so try and find revised parts and it should work out for you another thing to mention the top mounts were made from plastic and when the wheel is turned (mcphearson strut) top mount would click in and out of its baring ring and that’s the noise

one other thing i should mention is the fuel shut off solenoid ? have you tested that it works ok ? has the car ever overrun when you turn the engine off ? or delayed starting ?

hi sorry i should explain things a bit better im new to forum talk it don’t matter if mechanical or electrical what you have to do is take off the spill of pipe which is the small return pipe on the side of the injector and put your own pipe on it to fill a small cup because when the car runs the injectors have to spill of un injected diesel so it returns back into the system so if you have an injector that don’t work properly it will either not spill of anything or it will spill of too much its a really good way of diagnosing mechanical failure also you need to do this to all 4 injectors at the same time when you have connected each individual injector to its own pot or cup as long as they are all the same size for measuring reasons next start your car and run it for a minuet or 2 until you got enough diesel in each cup so its measurable then measure each amount against the others and look for a difference in quantity then report your findings back to me be sure that each cup is allocated to a cylinder so you don’t mix them up ie cup number 1 = cylinder number 1 and so on ? also record the time it ran for and the exact amount of diesel it spilled of for that amount of time ? its the best way to diagnose the diesel works you should find the problem a lot easier this way all the best report back

no your not looking for leaks you disconnect each injector dribble off pipes and connect tubes all the same length and lead them into measurable cups then run the car for a measured amount of time and the results should be equal amounts of diesel in each cup ? this checks the mechanical side of things like the diesel pump and injectors its always the first thing any garage or mechanic does when diagnosing diesels after ecu read of course

look at the crank pulley bolt and start the car and see if the bolt spins and the pulley don’t ? if the bolt does not spin then its sheered off

diesels have the tendency to blow compression through the water system when they fail due to the large amount of compression and it would not run for 1 and a half hours without killing something i would say you got a fueling problem have you leak tested all the injectors if not do that first thing as this will give you all the info you will need as to weather you are dealing with a mechanical fault or an electrical problem let me know the results and go from their i suspect the timing advance in the pump is at fault but do the leak down test first ?

i have to agree with other comments make sure you don’t have any underlying engine faults ie ect sensor reading out of range as the automatic transmission sends a message to the engine ecu to cut throttle when gear changing ? also if engine all ok it may be something to do with transmission valve body solenoids get it on a good computer and read the engine and box ?
