Thanks for the replies! Well ive only just serviced the car with all new spark plugs aswel as cambelt and clutch! Ive only had the car 2 months and when i fisrt got it it didn fire at all so a little fault finding found that the main fuel pump under the car wasnt working so replaced that but i also put a new rubber boot on the lifter so ill go check that plug to make sure if not ill do the crank sensor! Before i bought it the car was stood in a garage for 13 years so maybe a bottle of redex as a lad mensioned at work might help?
