hi all, the wife's 1.4(hi-torque) automatic corsa 1994 has developed a intermittent "re" starting problem, it starts every time when cold, but if it's done a short run 1 maybe 2 miles it sometimes won't restart, but not every time. it happened today, so I removed the coil lead to check for a spark, but would only spark once when the ignition was first turned on, but it didn't while it was turning over ?? is this normal also the spark was yellow not the crisp blue I'd expect to see. any ideas ???. thanks in advance DAZ
