Replaced exhaust and I have codes now?
Posted 10 March 2013 - 08:00 PM
We checked the wires form the distributor and they were all firing.
I left my friends place and went to the auto parts store to scan the codes. The car ran really rough at idle and stalled as I was turning into the parking lot. I almost hit the sign as I lost my power steering suddenly. It was close.
They scanned the codes. I started the car and drove the 10 minutes home and the car ran perfectly.
So hear are the codes
P0403 - Exhaust Gas Recirculation Circuit Malfunction
po505 Idle control system malfuction
P0443 Evaporative Emission Control System Purge Control Valve Circuit Malfunction
I found this info on the interweb.
Any ideas? I have no clue what's happening. Thanks for any help

did you use your original o2 sensors or the ones that came with the exhaust?

no one slipped with a tool and hit any hoses or wiring?
P0420 can be caused by many problems, but exhaust leak is one.

Did you have the air filter box off to work from the top on the O2 Sensor connectors? Check the hoses.

The air filter never came off and the only the three codes i listed above came up on the scanner. No po420. I'll look at the hoses when I have a chance later today. Those plugs on the 02 sensors are a pain to unclip. Maybe something got bumped or knocked loose. Thanks for the thoughts. I'm hoping it drives ok today so I can get to work.
Update: I drove to work this morning and the CEL was on but the car drove fine. Better than it has in a while in fact. I just drove to another building and the CEL is off and all seems fine. Maybe it was just a computer hiccup??
