Straight to the point.. Pulled in the driveway last night with no other problems. Put the car in park, the idle started to jump from 1,000 to 300, back again and back again. CEL came on at the same time. I then popped the hood and of course it stopped. Went to drive somewhere it, no rough idle in park when starting it up. But it did seem to 'buck' a little while driving at a slow speed. Cruised home, no problems, didn't notice and RPM isssues.. Put it in park in the driveway, it did the same thing!
Turned it on the this morning, it did it for 2 minutes and smoothed out. Took it to autozone, got these codes; P0174, P0175, P0171, P0172.
Too rich bank 1
Too Lean bank 1
Too lean bank 2
Too rich bank 2
How is that even possible to run lean and rich at the same time? The car still has a warranty from the dealer I purchased it from, but this will be the 4th time it is back there in less than a month. I'm starting to get frustrated. They have replaced the coolant temp sensor, and an axle. But none of those had a CEL. This time it does.. I'm sure they will fix it, but I am curious what it could be??
