2001 kia rio runs rough when accelerating idels fine its like it has no power i have replaced plugs wires mass air flow fuel filter new ground strap it has spark

Hi,

please look into updating your battery and/or alternator in order to fix your power issues. If you can jump start your car, you can also get a free diagnosis of it's system from a place like autozone.

Thank you.

Neither of those codes depend on a bonding strap. Replace the MAF and the knock sensor.

fuel filter or mass air flow sensor. do a tune up

Wow, all of those parts, and did the mechanic check the fuel pump pressure ??
The a/c problem is another issue.

hello this is a fuel trim malfunction bank sensor 1 meaning O2 sensor is malfunctioning .Oxygen sensor

It may me the Transmission Modulator Value.
a small diaphram value that measures pressure and tells the transmission when to change gears. If the diaphram is leaking it never can measure the right pressure. its on the transmission housing. Just disconnect and screw it out.

i want to give you the right answer but the only thing i think of is the mass air flow sensor.

try your crank shaft sensor, sounds like the same problem i had , had crank shaft sensor replaced and it drove fine afterwards. maybe go to auto zone or something and see if that code comes up

Possible fuel injector cleaning required. Could also have oxygen sensors checked.

fuel pressure regulator on the fuel rail is probably it or the egr valve is stuck open allowing burnt fuel to flood the intake, im leaning towards the fuel pressure regulator because the o2sensor is probably reading rich or if its reading lean then i would choose the egr valve . good luck
