Will start and idle but no power?

Hello,

So you will be able to start the vehicle but it has low power and drivers slowly?
There are several factors can come in play when an engine produces low power.

You could have an issue with a clogged air filter or fuel filter, or even a weak fuel pump.
Plugged catalytic converter, dirty mass air flow sensor etc.
