I?ve been having a problem on my 93 940 b200ft ...
the car runs fine on LPG , but it runs badly when on petrol, under load
symptoms are:when on petrol, i hit the gas and it will hesitate ....as if the mixture is too rich or sometimes he will just stop revving ....and feel as if i had hit an invisible wall
if i keep pressing the accelerator it will continu to hesitate and make some bump noise somewhere in the front .....then around 2500rpm it will return to normal, and later between 3500/4500rpm will feel again like hesitating
under acceleration sometimes it misfires a lot , sometimes it misfires less........i hear some kind of backfire in the air filter box when this happens..or so it seems
what do you think it could be??
