My engine is ck 4, it has lost its power and seems to jerk when driving, it is not picking fast as it normally did. I have changed the plugs and also the lead wires but it only improved a bit. What can the problem be?

This sound like you may have a plugged exhaust system which restricts the flow causing the low power as you described. Here are a few guides that will help us get the problem fixed:

and we should rear the codes to see if there are any.

Please let us know what happens.

Cheers, Ken
