I occasionally have the feeling of boging or flat spot during partial throttle.
Around 2,800 and 5,200-Rpm.
Has anyone else had similar thing and eliminated it with a new aftermarket throttle body?
When I would let off the gas at a stop light the idle would dip down below idle say 200-rpm and gradualy come back up. It sound like a Throttle Positions Sensor?
Or would you suggest changing out the MAP sensor?

Please move this tread over to Under the Hood.
Thanks
