I'm hoping someone here more mechanically minded than myself might be able to help / advise me...
First I apologise that this is not a machinery question, but instead relates to my 14 year old Petrol Mitsubishi Carrisma - in my experience the quality of mechanical advice is far better from TBN users than anywhere else on the net
Today I was driving and stopped at a junction. The car often stutters a bit on tick-over, especially after driving at normal / high revs. However when it recovered from its stutter today, the engine made a terrible banging sound and smoke started to come out the bonnet. Convinced it had finally died, I attempted to move the car forwards off of the junction - but both first and second gear caused the car to go backwards!!! It was then that it occurred to me that when it nearly stalled, the engine must have somehow restarted at top-dead-centre and thrown the flywheel backwards, causing the engine to run backwards? I have never heard of this with petrol engines before (although do know it is possible with diesels)???
I immediately stopped the engine and then restarted it - everything working fine and drove me to my destination and home again (which was very lucky as I was off to get parts for our lorry which is also "broken" at the moment) :laughing:
Does anyone know what could have caused this and what I should check to make sure it's done no damage (and won't happen again)?
