Difficulties with Toyota GT86: Black smoke and increased fuel consumption

Hi guys, I need your help please. My Toyota GT86, built in 2018, petrol engine and around 68,000km on the clock has recently started having some problems. When accelerating, there is black smoke coming out of the exhaust, the engine light comes on, the engine switches itself off, it makes a lot of noise and no longer pulls away properly. In addition, fuel consumption has increased, I notice a strong smell of exhaust fumes and the car often stalls when idling. I haven't had a good experience with my garage recently, so I wanted to ask here first. My assumption is that it could be due to a fault in the fuel composition. Have you had similar experiences and if so, how did it go with your mechanic? Thanks in advance!

Hi, I had a similar problem with my 2015 Toyota Supra, which was found to have a fault in the cable/connector. My symptoms were similar to yours: black smoke, high fuel consumption, unsteady engine noise and the car switched itself off when idling. The solution was finally to replace the faulty cable/plug. It was a serious matter because the car wasn't running properly at all. But since the repair, everything has been running smoothly again. It might be worth taking this up with your garage. Hopefully that will help you!

Hi, thanks for the tip! We must have the same problem. Your situation sounds pretty similar. How much did it cost you to replace the cable/plug? And did you have any problems with it after the repair? Is everything back to normal?

Hey, no problem, always happy to help! It cost me €95 to replace the cable/plug. And yes, everything has been running perfectly again since the repair. The engine immediately stopped making such strange noises and there is no more black smoke coming out of the exhaust. In addition, the fault in the fuel composition was also found and rectified. Since this was dealt with in the workshop, everything has run like clockwork! So don't worry, after that everything was really back to normal!

Great, thanks for the information! That reassures me. 95€ for the replacement sounds reasonable, and it's great to hear that your car has been running smoothly since then. So I'll contact my garage and explain the problem exactly as you advised. Hopefully I'll have the same luck as you. Thanks again!
