Question about 1998 Isuzu Rodeo

Open Question

Engine has flat spot while accelerating/cruising

My car feels like it is falling on its face when i try to accelerate at part throttle. it will also do it when i am at a cruising speed. it will clear up if i go full throttle spitting and sputtering a little. it has completely shut off a couple of times. i have done a complete tuneup recently but that has not helped. had a bad alternator last year and replaced both alternator and battery

    I am having the same problem, only now, once it starts, it won't stay running unless I constantly give it gas.

Internal combustion engines requires 3 things... fuel, air, and spark. You do not have enough of one or more of these. If the wires and plugs are old, change them.  Air filter, same thing.  Fuel filter can also clog up with stuff after awhile. When you take a look at the air filter check where the air comes from.  It is possible a little critter has built a home and blocked the air flow (rare, but, it has happened).

SOURCE: My 2003 Ford Focus ZX5 check engine light came on.

Have you hooked this up to an OBD11 reader yet ?
May be a bad crank, cam or knock sensor. Cars today are loaded with sensors.
If you don't read the codes you will be chasing the rabbit down the hole. ;-)
Hope this helps

Make sure the cable from the pedal to the throttle is good and hook up
to the throttle. When you press the pedal it should pull the throttle to open.

2007 JGC 5.7 Hemi hesitates to accelerate when the vehicle is at cruising speeds above 35mph. When it is at a constatnt speed and the throttle is at a fixed position it feels a bit jerky as well.


I suspect TPS (Throttle Positioning Switch) they're basically a rheostat that controls throttle movement. After a while, spots that get most used develop "Hot Spots" - and will cause a surge or hesitation when at that location. Replace TPS.

Cruise control went out on my 2005 ford taurus and my accelerator gets stuck at times. Should I replace the cruise control?


This is a dangerous defect. What you want to do is isolate the Cruise cable from the Throttle mechanism. Then get the Cruise cable away from the Throttle so it can not jam the Throttle accidentally.

With the engine OFF use your hand and move the remaining Throttle mechanism and feel for sticking or roughness in the control. If you feel binding, start removing the connection of the Throttle cable and work your way through all the moving parts like a Butterfly flap on the Airhorn, the TPS (throttle position sensor) and so on until you find out what is rubbing.

It is possible that the Cruise was disengaging because the Throttle parts were binding. If disconnecting the Cruise eliminates the sticking throttle, then all the problems came from the Cruise control cable or the Cruise Box. Once you have made a thorough check of the Throttle you can blame the Cruise for your problems and replace the parts.

check for a vaccuum leak this is where i would start if it rolled into my shop. possibly a PCV valve sticking or a hole in the hose, this hose should run from the valve cover, or crank case and then to the intake, or carb.

Flat spot in 2007 5.4 F150 ,when cruising ang hit


Problem is you can't adjust it. Chk the Throttle position sensor. They get worn in one spot and affect acceleration smootness.

Accelerator sticks


Take off the throttle body (very easy to do) and use carb cleaner to clean off the gunk. You have to clean both sides of the butterfly.

My 1998 Volvo does the same sometimes. Better petrol helps for me, these engines like the higher octane petrol. My car does not like the BP petrol at all for example.
