Answer -
Answer:
How many miles on your car?
Where are you, nearest major city?
How is the power, like a rocket or rather weak?
Is the exhaust manifold rust red or more white?
With the engine running, if you remove the oil fill cap, does it puff smoke like a train?

AnswerAnswer:
Unbolt the exhaust from the manifold, and try starting the engine.
If it starts easier, there are 90% odds the catalytic converter has failed.
All of your air breather hoses should be brittle (cracking with age), they should be replaced.
