My 2003 Freelander is idling erratically when I start the car. When I push the gas pedal down nothing happens


Hi and welcome to FixYa!

There are two things that can result to this issue. It's a bad MAF (mass air flow) sensor or a failing TPS (throttle position sensor). If one of these sensors are faulty, an erratic idle or unresponsive throttle will be expected. As a first course of action, have it looked at and replace if necessary.

Hope this helps and thank you for using FixYa! Have a good one!

2003 ford exp 4.6L jerks between 45-55 mph. just had complete tune up all plugs were changed out, fuel filter etc...


Replace TPS (Throttle Positioning Sensor) It's a rheostat that controls throttle. After time and mileage it develops hot spots/wear in areas that get most use. In your case the 45-55 mph area of rheostat. Your description is spot on to symptom of bad TPS.

TPS? Car studders at low speeds when climbing hills


YOU HAVE A TORQUE CONVERTER LOCKUP ISSUE, HAVE SOMEONE LIKE THE DEALER,AUTO ZONE OR IF YOU ARE HANDY CHECK FOR CODES, NO CODES....THEN TAKE THE CAR OUT STEADY DRIVE AT AROUND 45 MPH, GENTLY HIT THE BRAKE PEDAL JUST ENOUGH TO MAKE THE REAR BRAKE LIGHTS GO ON BUT NOT HARD ENOUGH TO STOP THE CAR...DO YOU FEEL THE CONVERTER SHIFT IN AND OUT EACHJ TIME THE BRAKE PEDAL IS TOUCHED MAINTAINING A STEADY 45 MPH SPEED, IF IT THAT SAME SHUDDER YOU ARE FEELING THE TORQUE CONVERTER NEEDS TO BE REPLACED, NOT AN EASY JOB AS THE TRANSMISSION HAS TO BE REMOVED TO GET AT IT.SORRY ABOUT THE CAPS.......

1993 olds cutlass supreme 3.1 multi port loading up at idle


Here are some of the causes of surges, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.

Engine runs rough after about ten minutes /idles really low


Just trowing some suggestions out there, but, I would check the idle air control valve (solenoid) or the throttle position sensor. If they check out then my last guess would be the map sensor or the vaccuum to the map sensor. Hope I was able to help. Best wishes.
