Thats sounds crazy.

It may sound crazy (I have no idea what it means), but Baer has enough rep (not just rep points, but what I have observed) that it behooves one to pay attention to him.

It's not it happenes more than you think!!!

P0122 Throttle position sensor

P1239
P2132
P2133
P2135

The ECM controls the electric throttle control actuator in regulating the throttle opening in
order for the idle position to be within +10 degrees.
The ECM regulates the opening speed of the throttle valve to be slower than the normal
condition.
Therefore, the acceleration will be poor.

the things I'm posting are what causes limp mode.

(relating to you)

P0102 Mass air flow sensor circuit
P0103
P010C
P010D

Engine speed will not rise more than 2,400 rpm due to the fuel cut.

P0607 ECM

VVEL actuator motor relay is turned off, and VVEL value is become at a minimum angle.
Engine speed will not rise more than 3,500 rpm due to the fuel cut.

This has happened to alot of people here

P1805 Brake switch

ECM controls the electric throttle control actuator by regulating the throttle opening to a
small range.
Therefore, acceleration will be poor.

Vehicle condition----------------------Driving condition
When engine is idling-----------------Normal
When accelerating---------------------Poor acceleration
