hi, i'm wondering if anyone has a diagnosis for this problem.
i was driving along when my rev counter stopped at 2000 and wouldn't move.

it then kept caughing and back fireing like mad when i accelerated.

it won't start with the key but it will bump fine. the rev counter now sits at zero even when i drove it home.

there are no mods to car except dump valve and exhaust and car is mint with only 50kmiles

help!!!!!!
