Question about 1999 Chevrolet Blazer
Have recently purchased the above truck, and found it is running at 5km/l of fuel, it has had new air filter put in, new thermostat as it was running cold, made no differnce, then did all the ht leads, new spark plugs, distributer cap, and new dizzy, this has made a slight difference but still not up to my mates 10 - 11 km/l, it has since been to a high performance mechanic for tuning on the dyno, this has resulted in nearly 6.5km/l.
has anybody got any ideas on where else to start looking to resolve this issue, i like the truck and dont want to have to sell it.
look forward to some helpful responses
See if you get any black smoke on start up if so replace oxygen sensor,
