I have been noticing that while on the freeway and displacement on demand is in effect, switching from 8 cyl mode to 4 cyl mode, I am able to notice and it gets harder and takes more effort to press the gas pedal down and make the car go faster and back into 8 cyl mode. I also have to push the pedal down a little further than normally expected. This has just started happening a few weeks ago and I have no idea why. Everything else with the car seems good, no CEL light and it runs smoothly while in 8 cyl mode. Would you have any idea about this? Plugs and wires are brand new, fuel pump is brand new.
have the same problem?
