My Wira SE 1.5 Auto went jerking and the check engine light went on while driving today. It recurred again even after I changed my MAP sensor last two weeks and my total body two days ago. Went to the Taman Midah Proton workshop as I used to go there, even the mechanic there don't know what's the cause. Any idea on what's the real problem guys? And does exhaust malfunction can cause the engine to create problems? Because I noticed my exhaust noise became slower and gentle when this happened. Not much vroom vroom on the exhaust

Guys, my Wira SE 1.5(A) seems to have its previous problem arising again. About a month ago, the car suddenly like lose its power while I'm driving and the CEL lights came on. When I step on the gas pedal, the car will jerk when the RPM hits 2K. As soon as the car came to a stop, the engine went off. I switch off the car, pull out the keys and then start it again, the CEL light is still there, but the jerking and underpower seems to go off. Went to a Proton SC to get it diagnosed, and long story short, the MAP sensor and Total Body was faulty. Got them both replaced straight away and I thought, the problem is over.

Today, while I was driving, the same thing happened again! Now I'm clueless on what is the real problem. Based on what I searched in the net, it might be the O2 sensor, but I'm gonna get it diagnosed again later today anyway. Anyone who has encountered such problems and have a conclusive solution for this matter?

My WiSE fuel gauge is not reading the fuel in the tank properly. How on earth does RM60 of fuel only fills 3/4 of the tank? Wira has a really big tank meh?

Bro whats the total cost for the whole change that you've done? I've a WiSE as well, planning to convert the gearbox to manual. Darn so much problems with my car right now. Just now the front lip tow cover went flying while I was driving, sigh
