just got my 2002 lancer oz rally
hey guys i am new to this site and i just got me got my lancer oz rally last week . the car came with 135000 miles on it and all the changes i did so far are
1.new spark plugs
2.new brakes pad and rotors
3.drained oil and changed the filter
4.power steering flush
5.new battery
but today i went to auto zone because the check engine light came on with P0421 Warm Up Catalytic Converter Efficiency Below Threshold and since then the car has been acting strange as its misfiring . Any ideas on wether i have to change the coil , cat converter or o2 sensors .

have u check the plug wires/coil packs? the price of the first o2 , the one that sits on the header, sensor is under $20 last i check.. id replace the first o2 sensor first.. if the second o2 is bad, tht one sits on the cat itself and is more exp, tht one is around 300 last i check at autozone.
i havent bothered to replace the sensor on mine since i passed smogg in feb of this year...

i have tht exact same code come up on mine p0421 with 75kmiles 03 oz... i think tht code refers to the o2 sensor off the header.. mine has been like tht since april and i have no issues driving or starting up engine. the lancer drove fine to cypress, ca from san diego and back for mod 11....
