All my XJ's do this,the 96 I used to have and 97 and two 99's I own now.All are 4.0 5 speeds.
Let's say you are in second gear at 2500 rpm then floor the gas pedal.The engine accelerates good then around 3500 rpm there's an increase in power that's noticeable.It's less noticeable in higher gears but still there.
I've felt this effect on some other vehicles like 4.3 Chevys.
Is this engine management programming to deal with emissions?
