Default My GX470 DOES NOT RESPOND TO ACCELERATION IMMEDIATELY ABOVE 50MILES PER HOUR?

My Lexus GX470 2008 MODEL does not respond quickly to acceleration above 50miles per hour. I have just changed the set of plugs. What is the problem?

Moving to the right forum .. Salim

Is this a different behavior than what it was like when you bought it?

When was the last time you changed the transmission fluid and the fluid in the transfer case and 2 differentials?

Could be alternator going out. My GX was sluggish for a while, but didnt throw any codes, until finally the alt died and the battery light came on but still no service engine codes. Changed alt and car has pep again. Must be something sensitive to low voltage in the electronics or possibly drag on the accessory belt?

What kind of plugs did you use when you replaced them?
