Wj v8 rpm problem not upper to 4000
Hello guys
I have one wj v8
my first gasoline jeep
she is good condition but little problem with engine
he sound good and good acceleration
but to 3500-4000 I can t up
In parking position and N or D
when the car want to accelerate, she is blocked to 3500-4000 not upper
i have change many parts
but I don’t know what is this ….
i am sad not to find the fault
does anyone have any idea about the cause.
fuel pump and filter. spark plug and ignition coil, throttle sensor and idle speed regulator
I removed the catalytic converter and disconnected the lambda sensors. only the map sensor remains, I saw that on the obd the throttle sensor did not give full opening 12% -76% max
thank you in advance for your help
