Honda fit sputtering
My 2007 honda fit had some sputtering problems while on idle. I knew car
suffers from this so i replaced all 4 coils and spark plugs. That seemed to be
its problem throughout the past years but now the problem persists even
though coils, spark plugs were replaced. CEL was on so I scanned it for codes
and it threw a P1100 or something indicating it was the O2 sensor so I
replaced it. I also replaced the fuel pump filter and check engine light turned
off but the engine is still giving me that sputtering failure. No CEL like I said,
And dunno what else could it be. Any suggestions? Car has 184k miles on it
and I am the sole owner. Thanks
Try using some Techron fuel injector cleaner and always use top tier fuel.
It used to be that only Union 76 was rated top-tier. It appears that a couple of years ago, the government or the petroleum industry changed how ratings are done, and now every gasoline, except independents, is rated top-tier: even ARCO, if you can believe that..... This is a somewhat common problem on older cars and can be avoided by regular tune-ups that include proper cleaning & repairs. The leading causes for engine sputtering is faults in the fuel system: worn out fuel pump, clogged fuel filter, dirty or defective injectors, and this can cause misfires. leading to damage to the catalytic converter. Do try a fuel system cleaner; I'd recommend Seafoam for a car this age. Then have the fuel system tested and repaired.
