Delay in engine picking up

[jiginc]

Delay in engine picking up when accelerator pedal is pushed down hard.

In fact it some times it almost stalls. It’s on petrol and LPG. LPG amplifies the problem but it is certainly on petrol as well.

The car has had new spark plugs and leads plus two new coils all OEM.

Any help welcome.

Thanks

Could be an air leak of some sort giving a weak mixture, check manifolds, gaskets and bolts for tightness and any loose or disconnected air pipes from the manifold.

Sorted.

The problem is the MAF.

A new MAF was tried to sort out a backfiring but the company supplied the wrong MAF. The one supplied was for a Mercedes not a d2.

Will now have to try and get it swapped for the right one. Thing is the old one seems to be OK.
