what is wrong with my car?..my eml light is on AND... (i`ll cut the long story short ), i fitted a janspeed manifold + sports cat a few month ago which involved cutting and extending the upstream lamba sensor .everything went well( for a while anyway) then the car started to lose power, it wouldnt rev past 2k-3k. the car just chokes everytime i put my foot down.
the mechanic thought it might have been the extended lamba sensor so we replaced it. the problem remains.
had it diagnose a few times but no one seems to be able to find the answer.
does anyone know what this problem is? or even better direct me to a mechanic?
thanks
ps. forgot to mention i have my lamba sensor unplugged atm this seems to stop the problem from occuring, but when its back on the above issue kicks in.
this car is a 2002 mg zr 1.4
