Check you TPS (Throttle Position Sensor) this will also cause the high idle.

The idling problem sounds like an idle sensor or the trucks choke is stuck on. The manual shift could be a transmission sensor of sort. Not an expert with the F-150 but I would speculate the two problems are unrelated to one another

SOURCE: rpm running high when park

well. your idle is just high. you can get a screw driver and find the idle screw on the throttle body. . and jsut adjust there , , that is if there are no problems.

now it also maybe a leaky intake. . . . but i think its jsut more of a small adjsutment. . 8)

Sounds like your trans is stuck in limp in mode. Could be something simple as a sensor, or something major as the trans or the computer. Will need to be computer diagnosed.

05 Durango 545fre engine runs strong but limit is 3800 rpm and trans will not go into overdrive


Need to check and see if the PCM is reading the PRNDL/ Range selector switch on the transmission. Could be a fuse, wire, or switch that is bad. At 3800 RPM's , sounds like the PCM is cutting out the engine. This happens in park or neutral. Yes the transmission will still shift from high pressure.. Usually hard shifts. Takes a scanner.

2004 jeep liberty won't move when put in gear (like brakes are locked).crank it in neutral put in gear it will go till i touch brakes then won't move again.WHAT'S WRONG WITH THIS THING.


gear, is this a Manual trans? or AUTO you said gear.
what gear, please name the gear, 1,2,3,4,5 R
or PRNDL ( a/t box auto matic) what shift lever selection?
what is out door air temp, you do know brakes can get wet and freeze right?
it wont go you meant? until brakes are touched, key word won't?

ok engine only starts in PRNDL set to N??
is that it?
and then when you shift to D, the car will not move
what about the other gears.? try them all yet?

my guess (wild) is that you dont know how park lock out works.?
that you must hold the brake pedal down to shift to park or neutral.
is that it? (read operators guide?)

my guess is car is not drive-able. key point1 (a dead car)
point 2, engine starts and runs. and races on demand with gas foot.
point 3, im lost. (no trans stated or clear symptoms.)

my jeep has 6speed manual box
and the clutch allows me to start car.
on Automatics trans must be in park or neutral to crank engine.

"it will go till i touch brakes"



I read that 10 times,
my 2nd guess. the engine stalls ?

IS THAT IT, stalls means engine RPM is 0
and right foot actions are dead.
and all dash lamps glow, telling you STALL is now.

Why does my car jerk when i change the transmission from park to drive


the idle RPM is too high
or its just too cold,
how cold is it outdoors?
idle speeds cold can be about 1500 RPM/ cold.
and will ****.
it jerks because you are taking 0 torque from engine
and the sending that to a stalled rear axle.
this cause a ****, that is why the park lock out requires Brakes on
so yo dont run over things.

When i shift car from P to R or D the rpm suddenly goes to zero and then suddenly goes to approx 2000 rpm.


that should not effect the driving of the car,it's do to the loss of connection in the gear shifter.

How to fix code e98 1991 deville


Probably two different issues.

The code is saying the computer sees the engine RPM is too high when shifting between park neutral and drive.
The rough idle would be something else.

Automatic transmission


Transmission will never hold the engine back if it is going through the gears properly.If it gets into high gear, eventually the engine will reach "redline" if you stay into it long enough. ("redline" for any engine is the point at which it cannot run any faster without harming itself.) DO NOT confuse that with proper shift points which should happen just before you reach max torque which happens way before you reach "redline" at which point you are way past the torque peak of the engine, and making no usable torque or horsepower. An example of this is a race engine with a max rpm limit of 10,000rpm.("redline") Depending upon the torque curve (determined by compression, stroke and type of cam grind) you would likely be shifting gears at about 7500 to 8500RPM not at 10,000.
Therefore, your shift points are like climbing a ladder. you get just so high and though there are more steps, you will fall off if you go there. Each time you shift, you are putting the rpms back into the usable power band, till you reach the next step, then start over again. If your trans shifts early the engine will lug and labor. shifting too late and it will quickly reach "redline" and self destruct or go "flat". In a conversion, you need to make sure that the electronics that control shift points are working within the usable torque range.
OR install a manual valve body and shifter and control it like a stick shift car, using your brain as the computer and a tach to tell you where you are.

Can a 1998 4x4 S-10 blazer be dinghy towed?


Yes it can, just place your Transfer Case in Neutral position.
Shifting into NEUTRAL
To shift the transfer case to NEUTRAL do the following:

Make sure the vehicle is parked so that it will not roll.
Set the parking brake.
Start the vehicle or turn the ignition to RUN.
Connect the vehicle to the towing vehicle.
Put the transmission in NEUTRAL (N).
Shift the transfer case to 2HI.
Simultaneously press and hold the 2HI and 4LO buttons for 10 seconds. The red NEUTRAL light will come on when the transfer case shift to NEUTRAL is complete.
Shift the transmission to REVERSE (R) for one second, then shift the transmission to DRIVE (D) for one second, or FIRST (1) for vehicles equipped with a manual transmission.
Turn the ignition to LOCK.
Place the transmission shift lever in PARK (P), or FIRST (1) for vehicles with a manual transmission.
Release the parking brake prior to towing.

Shifting Out of NEUTRAL
To shift out of NEUTRAL:

Set the parking brake and apply the regular brake pedal.
Shift the transmission to NEUTRAL (N) and turn the ignition to RUN with the engine off.
Press the button for the desired transfer case shift position (2HI, 4HI, AUTO 4WD or 4LO).
After the transfer case has shifted out of NEUTRAL the red light will go out.
Release the parking brake.
You may start the engine and shift the transmission to the desired position.
Excessively shifting the transfer case into or out of the different modes may cause the transfer case to enter the shift protection mode. This will protect the transfer case from possible damage and will only allow the transfer case to respond to one shift per 10 seconds. The transfer case may stay in this mode for up to three minutes.

NEUTRAL: Shift the vehicle's transfer case to NEUTRAL only when towing your vehicle.
Good luck and hope this answers your question.
