    I have a VS V8. It has done 180,000 klms. I recently believe I got a bad batch of fuel which caused huge running problems causing me to replace the plugs and clean out the throttle body. Since then, it has become hard to start when cold. Normally when hot, on the first turn of the key it fires almost instantly. But when it is cold it takes 2, sometimes 3 engine cranks of say 3 to 4 seconds each before it will fire. When it eventually fires it seems to run rich for a couple of seconds (clearing its throat) and then everything's normal - idle is OK and restart is OK.
    Any ideas? :unsure:

    Update on Hard Start

    If the car is left to stand when hot for say 1 hour, then it can be hard to start, but not as bad as when it is cold. :bang: If it is cold or hot and I have just started it and then turn it off. It will usually start without a problem if I try to restart immediately.

    When you say you has a bad batch if fuel just what do you mean? - if full of crap then the filter on the fuel pickup pipe could be blocked or the fuel filter itself may be blocked...if stale or having contaminents like extra ethanol, thibane or whatever then your injectors may be extremely dirty. The contaminents in the fuel may have stuffed the oxygen sensor as well. Good Luck.

    hmmmm, good questions!!!!
    First of all - there are no error codes - just 12.
    The idea of bad fuel - The fuel level in the tank was down to the last 4 or 5 litres. Suddenly the car was missing, wouldn't idle - a regular basket case. I then filled up with "good quality" (Caltex) fuel plus an injector cleaner additive (also Caltex) - the differnece was amazing. The idle instantly improved and continued to restore (over about 100 klms). To check the filter and oxygen sensor, where abouts is the fuel filter and oxygen sensor?
