Hello, I would need your advice. I drive a 3 door vitara ,Bj 2009, 78kw, 1,6l. Recently he lost power during the ride and ran round, took only heavy gas, as if he had too little air. I got out and found the back at the exhaust almost no air came out. When I put myself under the car, I saw that the whole cat was glowing red. I immediately turned off the engine. After a few minutes I started again and the engine ran back normal so that I could I told a mechanic who said that the cat had melted. Then I took off the exhaust part and removed the whole cat. The car worked perfectly again. Must say that I drive almost only short distances. Now for a few days he does exactly the same again. At some point under driving he goes to the knees and does not run properly, goes max 70kmh, and needs much more fuel. If I put him off and wait he goes after a time again I often drive only 5km, and even 100km and it happens. Had it now with a mechanic, there the lamda probe was replaced in front of the cat, which was also completely melted. A new one was installed by almost 400 euro. Everything was looked at and examined, but nothing found. the new probe simply does not get any current. Now my question, why did it come to this that my cat melted, and what could be the mistake that the new probe did not I am grateful for every tip. wish you a nice day
