Car wouldn't start this morning, and while cranking was making a really weired noise. After cranking a while, I got it going and kept it running by giving it heaps of gas, and then it stalled. Started it again after a long crank, then it was running really rough, making a regular clanging noise... Let it idle for a 10-20seconds, then it smoothed out and all was fine. Every other start today has been instant and trouble-free.
I'm thinking that perhaps the ICV was just stuck first thing? Sure as hell scared the **** outta me. Hopefully it was just a one-off freak occurance.
