Check the idle air control (IAC) solenoid. If the solenoid doesn’t respond properly, you’ll have this type of issue. If possible, remove the IAC and connect direct battery voltage to the solenoid and see if it works properly. Also, check for carbon buildup in the sensor itself and the throttle ports where it mounts.
My car runs fine for a few minutes, then starts sputtering and loses a lot of horsepower. It doesn’t stall but the engine sounds rough like an old 80s car. A night of rest lets the car become drivable again for a few minutes but then the issues show up again. I’ve changed the spark plugs, plug wires, distributor cap and rotor, air filter, cleaned the maf sensor and changed the throttle position sensor. What else could be the problem?
My Golf mk4 1.4 16v 1999model is misfiring on the first cylinder (all the way to the left cyl). Spark plugs, ignition coil, spark wires, and fuel injector connection is good on all 4 cylinders. I got a fault code saying (DTC) "00282 Throttle position actuator DTC status: open or short to plus." Is this guaranteed to be the Throttle position sensor causing only misfire on the first cylinder?
My 2011 Ford Escape started running rough. The mechanic changed the head gasket and suggested we change the plugs and coils. We did that, but the car completely stalls out after a few seconds of running now. We have replaced the fuel pump and throttle body as well. Code reader shows misfire on cylinder 1 and 3. What is a reasonable next step?
I’m using a Toyota Brevis 1JZ engine. It’s been diagnosed several times, and it was reporting throttle motor malfunction. I changed the throttle body. It starts one time and then fails then it keeps on cranking. You change the throttle body, it repeats the same process. The spark and compression is there. What could be the problem?
I'm driving a Chevy Cruze 2013. I tried to take the car out of the yard last time and the car did not move. I can put gear one and two but the car is not moving. It does not engage from gear 3 up to reverse. When I start the car it starts fine, but when I let go of the clutch, it switches off. Sometimes, I will hold the clutch down for a while and the car will start to jerk. Please help. What could be the problem?
