Recently the mk3 has developed a problem with starting first thing in the morning. The starter motor will turn and turn and turn, but it wont catch! When it eventually does, its a bit lumpy, smooths itself out and then it feels fine. Until you go from first to second gear and there is a loss of power. Eventually, when the engine warms up, its fine and drives completely norma and I wont get any more starting issues for the rest of the dayl! I also noticed this morning, it was low on water, which it never has been before.
Since this problem started, I have replaced the spark plugs, the dizzy cap and rotor arm, and the air filter and also the rocker cover gasket (which was leaking) and also replace the throttle body to inlet gasket, as that was pretty much in two pieces lol! The HT leads looked pretty new, so I didn't replace these. Could it be as simple as replacing the leads? I don't want to buy more parts, unless I know it's going to fix the problem.
Any help would be greatly appreciated!
