2007 Hyundai Tiburon Exhibiting Start-up Issues, Drop in power, and Black Exhaust Smoke

Hey there! I can totally relate to this - I had a similar problem with my 2004 Hyundai Sonata not too long ago. That rough idle and black smoke sound all too familiar. Once I noticed the issue, I headed straight to a reputable mechanic. After running a few diagnostic tests, they informed me that my car’s injector was internally defective. This, they explained, was causing both the rough idle and the black smoke from the exhaust. Truth be told, it was a serious issue I couldn’t ignore. The main work involved replacing the faulty injector with a new one. The aftermarket parts are pretty reliable, so that's what we went with. They also did a pretty solid clean-up, making sure no residue was left in the system, to prevent further disruption. This fixed the problem and my ride's performance improved significantly afterwards. I think you'll be looking at a similar fix, given the symptoms you've described. Good luck with sorting that out. Remember to find a reputable mechanic; if you don't trust the one you're going to, try someone else. Best of luck!

Hey! I've gotta say your experience sounds eerily similar to what my Tiburon is going through right now. It's daunting to think the injector could be the culprit, but it's comforting to hear you've dealt with something similar and lived to tell the tale! If it's not too much to ask, do you recall how much you ended up shelling out for this fix? I know it's all gonna hinge on the mechanic's rate and the part's cost, but a ballpark figure could help me prep my wallet. Oh, and since you got this sorted, have you noticed anything else funky going on with your Hyundai? I'm hoping once this is done I can finally enjoy a smooth ride. Thanks for sharing your experience, it's really helping me out!

Hey, no problem, always glad to share my experiences if it helps someone out! For the injector issue with my Sonata, I ended up parting with 515.00 €, though keep in mind prices can vary based on your location and the mechanic's rates. This covered the cost of the new injector and the labor for replacement along with the cleanup. Since it's an internal fix, it may seem a bit steep, but trust me, it was totally worth it afterward. And to answer your other question, since the mechanic sorted out the faulty injector, I can tell you my Hyundai is running smoothly like never before. No more funky stuff, no more black smoke, and certainly no weird shakes or stutters. It feels like it got a new lease on life! Remember, a good mechanic will do more than just fix the immediate problem, they'll prevent the long term stuff too, so make sure you find someone you trust. Hope this helps and best of luck with your own fix!

Thanks a bunch for the detailed response! I was fearing a big hit to my pocket, but 515.00 € seems reasonable given the situation. Your insights have given me a clear idea of what to anticipate, and I feel better equipped to get my Hyundai back on track. Relieved to hear you haven’t encountered any more trouble with your Sonata post-injector fix. That gives me hope that once this hurdle is crossed, my Tiburon will be smooth sailing too. I'll make sure to keep your advice in mind when picking a mechanic. Someone trustworthy who can do more than just quick-fixing the immediate problem is the way to go. Appreciate your help! Going to sort this out ASAP!
