Idles fine. Replaced throttle position sensor did not fix problem. Runs fine sometimes other times when you step on gas starts the lurching
SOURCE: 2000 kia sportage ex, 4 cyl.
Yes there is a sensor that controls Fuel/air ratio.It's called a MAF (mass air flow sensor)
But I think you should have the EGR (Exhaust gas recirculation)valve checked
and The TPS (throttle position sensor)maybe dirty.
Although may things can cause this issue,I would look at the items above first.
Please rate this a blue fixya
SOURCE: Kia sportage jerks and hesistates to take off
the pump should do the trick but check the throttle plate.
SOURCE: I have a Kia SPORTAGE 2000.... wher is the
go to autozones website and type in your vehicle under parts locator section

evap purge valve fault is your p0443
p1693 is manu. controlled aux input output fault
p1693 is a code for an open or short to ground for the check engine light
does it light up when key is on? if so then it is a left over code from some previous repair attemt
the evap code wont prevent starting
check for broken timing belt
check for fuel in tank and that it has proper fuel pressure
SOURCE: changed timing belt on 2001 kia sportage but still runs rough
I would check the connectors on the coil packs, spark plugs and wires and replace them if they at all seem worn or tired. My 2000 sportage ran rough so I replaced the fuel filter, coil packs, spark plugs and wires, cleaned out the IAC valve, TPS, throttle body and intake tube, tightened the screws on the fuel pump access door under the right rear seat and cleaned the ground wire and the contact surface and I added 1 ground wire from the block to the firewall and 1 from the valve cover to the firewall. Your timing is more than likely right where it needs to be but the ignition may be slightly missing from a bad coil pack, dirty or fouled plugs or a bad plug wire.
