2017 Hyundai Creta Showing Symptoms of Rich Fuel Mixture: Looking for Repair Advice

Hey there, Gotcha! Had a similar problem with my 2014 Hyundai Tucson, only 19k miles on it. Like yours, my engine was acting funny - lost power, poor fuel efficiency, black smoke, the works. Turned out the fuel pressure regulator was the culprit. It was running too rich, just like what you’re suspecting. Here's what went down at my garage. They ran some engine diagnostics first, confirmed it was the fuel pressure regulator. Once they got that sorted, I had them do a complete tune-up. Change the spark plugs, replace the fuel filter, and clean the fuel injectors. Granted, it wasn't a quick fix. The garage had my car a few days, but I'd rather that than risk it with a bad hack job. It's true, it turned out to be a serious issue. The defective fuel pressure regulator can damage other parts if not detected early. Sounds like your car is flagging up a similar problem. I'd recommend getting it checked by a reputable mechanic soon, it just saves a world of hassle down the line. Best of luck!

Hey! Reading this rang a bell for me, I had almost the same issues with my Hyundai not too long ago. The warning signs you've described nearly match what I went through with my fuel pressure regulator going haywire. Just thinking about your situation, I was curious to know how much did you end up shelling out to get your Tucson back on track? Also, as far as you remember, did anything else pop up after the initial fix or was that it? Stay safe with your Creta too don't let it slide for long. Cheers.

Hey! Good to see you came across my reply and it caught your attention. Yeah, my Tucson did give me a bit of a headache with that faulty fuel pressure regulator. It turned me 250 quid lighter, but hey, no more black smoke. Also, after the initial problem with the fuel regulator, I haven't had any other major problems. In fact, after I visited the mechanics and got the fix done, they did a pretty awesome job sorting out the error with the mixture control. It was running too rich just like yours but hasn't acted up since then. So, was totally worth it in the end! Best advice I have? Get your Creta to a trusted garage, and don’t let it linger too long. You'll thank yourself later! Take care and keep us posted.

Hey Fellas, Fantastic! You guys are a wealth of knowledge. Your experiences have definitely given me a direction to head toward, and it's comforting to know I'm not alone in this. Based on your advice, I finally took the trip to a reputable mechanic (none of those shady types, thankfully!). Much like your experiences, the culprit turned out to be the faulty fuel pressure regulator in my Creta. They're running some additional diagnostics just to be on the safe side, and are fixing the mixture control to sort out the richness issue. So, after hearing your costs, thought twice before raising my brow at the roundabouts of 300 quid for getting it all cleaned up, including a complete engine tune-up. Fingers crossed my Hyundai behaves after this! A big shout out to you both for sharing your experiences. Definitely helped me overcome that hurdle. Keep doing what you're doing guys, your candid sharing helps us non-auto savvy lot more than you'd realize. Appreciate the help! Cheers.
