Hey All,
Just after a few suggestions to increase the fuel efficiency of my 1997 VS Commodore Wagon. It's got the 3.8L V6 with an Auto (yuk). I haven't done any mods to the engine yet and I'm wondering if it would be worth while doing a cold air intake with a pod filter to increase fuel efficiency.
I'm running Premium fuel every 3 tanks and usually use 95 over 91 if I can. I'm doing a trip from Brisbane to Sydney soon and I'm looking to get a bit better kms over the trip. I've recently changed the plugs and leads to NGK stuff and I've replaced the fuel and air filters already. I've also given the throttle body a good clean out.
Other issues I'm having, it seems to be a bit hesitant (like it has a miss almost) on take off up to around 40kph, then it's fine. It's coming and going though, some days it's fine, others its really bad, that's why I replaced the plugs and leads, which made a small difference, but not heaps. Also it seems to have a problem when I'm cruising on the highway, if I'm going up hill and need to give it a little bit more to maintain speed the rear end starts thudding like it can't make up it's mind what gear to be in..
Any suggestions would be appreciated.
Regards
Paul
