Problem with my 85 Telstar

[debchow]

Hi there,

I am having some big problem with my beloved old 1985 telstar and I do not have much idea about cars. I am getting big clicking noise from the engine and it is getting worse every time I accelerate. I am not getting much race at the moment either.

The road side assistant told me the car is now running on 3 cylinders instead of four. He showed me that even after taking out one of the spark plug there is not much difference in the engine running. He further advised it could as simple as changing the spark plug or as complex as compressor (not sure) problem within the engine.

So wanted some advice from anybody. I appreciate your help
Thanks beforehand.

Dave
