Good day Nairalanders,
I urgently need expert opinions on this..
I have a car that has been misfiring and our present day mechanics thrive on trial and error cos even the diagnostic devices now in use does not seem to do much as they cannot interpret the codes on display.

I went to one mechanic and he insisted it is fuel pump even after the diagnostic test did not mention fuel pump.

Another one said its plugs.. We changed all 6 plugs yet problem wasn't solved.

I took it to a mechanic recently and decided to just do a scan and post the codes here.

Maybe auto experts can assist me.

The codes are p0420, p0441 and p0430.

Thanks
