Reduced engine power
Reduced engine power
What would cause my 2002 Chevy trailblazer to cause reduced engine power and check engine light to come on? It also wants to stall out and idle rough especially when AC is on
Re: Reduced engine power
you should have your vehicle scanned to see what codes you might have.
One common problem with reduced power showing up is the throttle sensors. When the pairs of throttle sensors don't match up to what the computer wants to see, it doesn't know which set is correct so it will default to reduced power mode.
with the throttle by wire systems some throttles don't have and Idle air control anymore. they use the throttle to control the air to keep your engine running at idle. So if you have a problem with your electronic throttle it will affect your idling as well as your driveability.
