check engine light help needed
dont have the code but it was pulled a couple weeks ago and it showed a downstream issue. since then I put a new air filter, new spark plug and ignition coils. since doing this the engine light has been off for 10 days.
today I started the car and the check light came on, drove it around close by and the rpms were bouncing a little bit, good idle at stop light. the first mechanic told me the oxygen sensors but I dont want to throw parts at it, but Im guessing thats the issue.
car has 61,000 miles.
