help why my engine tremble on cold start.

[sds]

hi bros,
need help cos csa at performance cant solve the problem.

almost 3yr old e60.
on cold start every morning the engine would tremble and kind of move back and forth,refuse to crank or break down.

rpm idle is around 600-900.

they say it was injectors,so they changed injectors, charged the battery but still problem persist.it only happens on cold start.

what could it be??

TIA

Did they actually check spark plugs, fuel filter and fuel pump? If injectors dirty then the problem should not be limited to cold start only.

Has PML acknowledged that there is a problem ?

Had this experience on my old ride E46, but not Cold Start. The problem occassionally happened after a long WARM drive and happened after the car was parked a short while.

Was told by my workshop guy that hose had broken, so the engine was getting erratic air intake, causing abnormal combustion.

Bro
Did you check the engine mounting? Mine was due to that problem.
