Chevy malibu: the spark plugs and inition wires one..test drive

This answer was rated:

I have a chevy malibu 2002. I just changed the spark plugs and inition wires one at the time. I test drive my car and there's no power. No pickup. What did I do wrong? The engine sounds smooth the only problem is theres no power.
Did you have any problem like this before the plug and wire change? Did you do anything else?
Customer: replied 7 years ago.
This is the first time I changed the plugs and wires. never had a problem before except there was a rattle sound underneath the car when the engine is cold.
Did you do any other work besides the plugs and wires?

Are you sure you have the wires on correctly?
Customer: replied 7 years ago.

i'm positive. When I changed the plugs and the wire I did it one at the time. I first removed the old plug then replaced a new one then change the wire. then I proceed to the next plug ..and so on.


Did you compare the new plugs with the old plugs?
Customer: replied 7 years ago.
yes. I even put the old ones back and was doing the same thing. no power. But before that when I have not changed the old plugs the only thing I noticed is miss fire. I found out that my ignition wire wire has a crack so I decided to buy a new ignition wires and plugs. Another thing in the morning when I start the engine I hear a rattling sound sound underneath the car by the exhaust pipe but it would only last about 30 sec then it will disappear.

These vehicles have a problem with the catalitic converters going bad and it is likely the problem. You can test this by removing the exhaust and taking it for a little drive. Pic below,
