    Default Running rich

    I noticed that my GTV is blowing out alot of un-used fuel. It seems to be getting worse but I havent really noticed any performance drops...... I literally have thick black spray marks on my drive up to about 800mm.
    Car has also been tuned recently and always been running on BPultimate.
    Any suggestions?

    Thanx

    theres plenty to check.

    o2 sensor, spark plugs worn, ignition timing out, faulty fuel pressure reg, sticking injectors, cold start injector stuck open all the time.
