On tuesday of last week, it got really cold outside (below 20 degrees). I went out to start my car and the idle was going crazy. It would continuously rev up to 2000, and back down to around 200 rpms before it goes back up again. Sometimes the car would stall, but it would always start right back up if it did. When I pull up to a stoplight, and I am holding the brakes, the revs fall again and sometimes the engine stops. If I hold the gas, the car keeps running.
I took my car to Autozone and Advance Auto Parts who each read my engine codes. The codes told me that I have an Idle Air Control Underspeed Error and that bank 2 is lean and that I have misfires on cylinders 4,5, and 6. I also got about 6 different oxygen sensor codes.
I spent the next few days searching the forums to find out what to do.
I broke my right arm in November and just got out of my cast on Friday, January 9, 2004 so I couldn't work on my car until this weekend.
I had a lot of fun doing everything with my left had. Since I had the dealership change my Idle Air Control Valve back in October, I figured that shouldn't be the problem. I ended up changing my plugs and wires.
Tomorrow I plan on changing my PCV valve and Fuel Filter.
Is there anyting else that I should look at while under the hood tomorrow?
