CHECK ENGINE LIGHT ON A lit check engine light in a vehicle is indicative of one or more problems including faulty oxygen sensors, leaking hoses or manifolds, damaged fuel injector O-rings, a blown head gasket and a loose or damaged gas cap. A blinking check engine light indicates an emergency problem that requires repair. Dealing with a check engine light on your vehicle’s dashboard can be frustrating. While the little light is meant to warn you of a problem – what the problem exactly is can be a mystery. Somewhere inside your vehicle, something happened to trigger the light.

ENGINE WARNING LIGHTS ON BMW X3 E83 2007 - the three warning lights plus eratic speedo plus erratic radio volume.

The fault can be something quite simple and nothing that’s going to stop the car to something quite major that will reduce engine power and possibly stop the engine.

2014 Ford F-150 8 cylinder 5.0 shakes when idling I recently purchased a 2014 Ford F-150 8 cylinder 5.0 It has high mileage 105k. The check engine light is on and the motor shakes when idling though it pulls strong at higher rpm. I had it checked the computer indicated an issue with cylinder #5. When tested further found that the compression on that cylinder was low 75psi the mechanic also put some oil in and tested again. Went up to only 100 psi. The mechanic is discouraging me from trying to repair and recommending I try to sell quick. Am looking for advise and a better explanation of what this could mean and cost? Don't know if I need to park the car until I resolve one way or another ( mechanic said I could still drive). Could it be so catastrophic I need to walk away? Get Your question Answered: The reason for the check engine light and the shaking motor is that a misfire was detected on the #5 cylinder. Now there can be many reasons for a cylinde...
