engine surging whilst driving
no problem with staring, idling normally,but soon as you drive at normal speed
the engine starts to surge...then go back to normal operation. once you slow
down and change the gears back, and excelerate the engine seems to fire only
on 2 cylinders and splutter, then back to normal driving. Opel Monza 1993 GSI
Sounds like it needs a good tune-up.
Evertything is replaced that we can think of...fuel pump, fuel sieves replaced, coil replaced, in-line fuel filter is changed, plugs is replaced... Now we think it could only be a electrical problem? Any suggestions how to fix this???
It may have something to do with the vacuum advance for the timing. Make sure the weights are free in the distributor, the things that have a spring attached to them, two of them, & the vacuum pull off is working.
my monza seems like its running on 3cylinders has a new carb and feul pump but has no driving power timming is fine
