Guys I hope you're all doing good.
I was riding in my friend's Mirage today and all of a sudden it dropped its RPMs from 2000 at 60KMH to 800 at 20KMH. The car's engine bay was very hot although it did not give an indication that something was wrong. 5 minutes later, it gave a check engine light. We had the car scanned and the scanner showed a malfunctioning MAF which was replaced at the spot.
After driving it for 5 more minutes, the car started to slow down and was shaking violently at only 40KM/h. The engine bay was extremely hot, no heat indication. Coolant and engine oil is new. Sparkplugs and airfilter is in good condition. The car's initial acceleration was so low that it could not even cross 20KM/h. Engine constantly makes a loud growl at 30KM/h and the whole car shakes violently if you give it full throttle which cuts off at 40KM/h.
On the OBD-II scanner, it gave no fault codes after the MAF replacement but the problem is still there. The mechanic said that the cat-con is damaged and maybe that is why its doing this. But how can a cat-con die at only 77000KMs?
The car is a 2013 1.0L Mitsubishi Mirage with a verified 4 grade auction sheet. Car has done 77000KMs so far.
Would really appreciate any response.
