Seeking Advice on Fixing Engine Troubles in 2004 Volvo XC90 Related to Air Mass Sensor

Hey folks, I'm having some troubles with my 2004 Volvo XC90 (Gas engine) and hoping someone here could shed some light. Symptoms include black smoke on acceleration, the check engine light being on, the engine turning off randomly, a decrease in power, shaking while idling, and a poor fuel economy. It's even started jerking when I accelerate and stalls while idling. I've got a hunch it could be something to do with the air mass sensor. Has anyone else been through this with their Volvo or have any idea how to fix it? Especially interested in any workshop experiences you've had. Cheers!

Hey there, not a certified mechanic but definitely a Volvo enthusiast with some experience. I had a pretty similar situation with my 2002 Volvo S40 a couple of years ago. It turned out there was Damage to the cable harness. I would recommend getting your vehicle's error code checked at an auto parts store or local mechanic. In my incident, I took my car to my local workshop, got the error codes, and they replaced the damaged cable harness. Bagged me around 95 Euro but it sorted the issue right away. Just to be sure, could you let me know the mileage on your Volvo XC90? Also, have you had any recent repairs or parts replaced? This information can help me offer more detailed advice. Phew! Car trouble can be a heck of a ride, but you'll get it sorted. Good luck!

Appreciate the advice! To answer your question, my Volvo XC90 is currently at 77777 KM, quite a milestone, ha. The last service was as routine, nothing major replaced or anything. I’m guessing your suggestion could work for me, about time I paid the local mechanic a visit. Thanks again for the help!

Not a problem! It's always good to share some car wisdom. Given those 77777 KM on your XC90, I'd definitely suggest giving the mechanic a visit and having those error codes read. It's the quickest way to figure out what's actually going on under the hood. Also, considering the age and mileage of your vehicle and symptomatology, apart from the cable harness, it might even be a good idea to ask them to check your fuel injectors as well. Clogged or leaky fuel injectors might also cause symptoms like power loss, poor fuel economy, etc. while also potentially damaging the air mass sensor. Remember to give them a detailed description of what's been happening. The more information you provide, the more chances are they'll nail the problem from the get-go. Stay strong! Car issues can be a tad frustrating, but they'll be over before you know it. Cheers!

Thanks again for the solid advice! I'll follow your tips and make sure to be thorough about the symptoms when I talk to the mechanic. I feel a lot better heading to the mechanic with some knowledge in my pocket. After all, knowledge is power, right? I'll definitely bring up the fuel injectors. Fingers crossed it isn't anything too serious. I'll let you know how it goes. Cheers!
