Q: Sunroof stuck open

I would verify with your Honda service department but typically the horn will only sound if you push the lock button a second time. This is to alert you that you've locked your doors again. The first time will flash...

You didn't indicate the age of the battery (https://www.yourmechanic.com/article/how-long-does-a-car-battery-last). If the battery is "new" (less than 2.5 years old) and passes a load test, you should check for parasitic loads (https://www.yourmechanic.com/article/how-to-diagnose-a-car-battery-drain_2). With all car accessories off and key out of...

Hi, thanks for writing in. I'd be happy to help you. Code P2104 (https://www.yourmechanic.com/article/p2104-obd-ii-trouble-code-throttle-actuator-control-system-forced-idle-by-jay-safford) relates the throttle position control actuator, and code P2126 (https://www.yourmechanic.com/article/-p2126-obd-ii-trouble-code-throttle-pedal-position-sensor-switch-e-circuit-range-performance-by-jamahl-walker) relates to the throttle position sensor. When either of these components is not working properly, this...

This is a common symptom of a misfire (https://www.yourmechanic.com/services/engine-is-misfiring-inspection) or potentially a faulty idle air control valve (https://www.yourmechanic.com/services/idle-control-valve-replacement) which when faulty, can cause the misfire to happen due to an improper air/fuel mixture being supplied to the engine. The idle...

Hello. If the shudder only occurs slightly under acceleration then it typically is not a dangerous problem. Most of the time it is caused by a bad engine mount or an issue with a failing cv axle (https://www.yourmechanic.com/services/axle-cv-shaft-assembly-replacement). If one...

Hi there. The cam and crankshaft position sensors (https://www.yourmechanic.com/article/symptoms-of-a-bad-or-failing-crankshaft-position-sensor) control the TIME in which the spark plug ignites; not the actual action of the plugs igniting. So, it is very possible that your hard to start issue is caused by...

You should have the computer and transmission scanned to see if the system is storing codes that can be fixed without an internal transmission issue. The codes will need to have the pinpoint tests done to isolate the problem.

I can't help but think that there is a little more back-story here. But I presume you bypassed the heater core because you had a leak inside the car. That's something you can do if you don't need heat of...

The vibration could be due to faulty motor mounts. To cover both that possibility, and the possibility that the vibration stems from an engine management fault, I would suggest that you request a rough operation/rough idle diagnostic (https://www.yourmechanic.com/services/car-idle-is-rough-inspection) and the...
