Hi all,
Having some issues with my car. Approx 78k miles, no major modifications. I bought the car around 20k miles. I've had all the recalls done except the ECM reprogram (it's going in for that soon). Here's what I've noticed (more or less in chronological order)
*SES light- P0420 Catalyst efficiency (Bank 1) below threshold.
*Extended cranking time before starting, and when it does start, it doesn't idle smoothly after starting like it used to. It doesn't do this consistently though - sometimes, especially if it's been running for a while, the car starts normally.
*While troubleshooting, decided that the air filter was pretty dirty, so I changed the air filter and the spark plugs (spark plugs were black).
*Problems (including the light) went away for a few weeks, then came back.
*Car has been going through more oil and coolant than "normal." Haven't noticed any smoke from exhaust.
*Changed spark plugs again, light gray this time.
Any ideas? Would the fix be fairly easy or should I just take it to a dealer and throw $$$ at them?
Thanks
Brandon
