Check engine light on
On my girlfriends corsa the check engine light comes on intermitantly and the car struggles to start, turns over fine just sometimes takes up to 20 seconds to fire up. Just replace collant temp sensor whcih was faulty but taht hasnt cured the problem. Thinking Air mass meter, plugs, leads or coil. What do you think?
Have you tried using one of the code checkers that plug in underneath the dashboard? That may help you in identifying the problem. Good luck!
