A Class misfiring
 

My S reg A class is misfiring. Has anyone got any idea why this may be happening. It was working correctly the other day and all of a sudden it is misfiring.

Any help would be useful.

Thanks.

first check plug gaps ,look under hood when its dark see if you have any sparks from HT leads ,may need new ones . remove distributor cap check rotor arm .these are all easy first checks & may turn up something .
