Hello all ....this is a post from down under (New Zealand)....my daughter has a 1996 1.8 VRG Gallant (97000km) and ever since it was purchased it hasn't run as good as it could ,whilst driving at a steady 100kph the car has a intermitant hesatation almost feels like a mis , mostly noticable on straight flat roads which we have plenty of in canterbury,also at times when accelerating it seems slugish and definately mises .After reading a lot of posts in this forum it looks like it is a common fault and to which no one has posted exactly what there remedy was. The problem was worse several weeks ago as the car was pinking pretty much everywhere it was driven (bad brew of fuel), that was when this forum was looked at and discovered that these cars should be run on high octain fuel,since purchased it has been run on 91 , straight away a big improvement was noticed and a can of injector cleaner put in the tank . Spark plugs have been checked and are the correct type NGK BKR5EKUD.Problem is still there .... Any help with this and where further to look would be great .....cheers Shane

It can be lots of issues, bad plugs , mad fuel filter , which would be restricting the fuel pressure , especially when its been running a while, and a lack of fuel pump pressurfe
