Hi I have a 2000 s and ju
st popped a cel 0302&0303. The car was running ok a couple of days ago now this. The car has 83k on it bought it with 58k and did the 60k maintenance at the stealership. Oil changes every 3k. So my question is how do I fix this problem. Is it ignition,fuel,or something else. Any help would be appreciated thank you.

 

I would try these

check or replace spark plugs
also perform a compression test at the same time.
report the figures to us.

swap cylinder 2,3 coilpacks with 1,4.
reset ecu.
to see if the codes are changed to P0301 and P0304

take notes of what you have changed and the codes. a cheap OBDII reader would be very helpful so you don't have to run to the parts store just to pull the code

 

Thanks for the advice. I checked out the site a bit more and found out a lot more about my problem.ill start working on it and report back
