My car has an engine code for the EGR valve, cylinder 3 misfire, and a o2 sensor. Now before you bash me, I love this car, but it's starting to get very frustrating. The a/c won't blow cold and for some reason won't blow out the vents at all. The other controls work ok though. Things I've done is replaced the sensor that was bad and cleaned the EGR valve which was not carboned up at all. I was replacing the plugs and had to replace the plug wire cuz it was the cause of the miss fire. It still hesitates when it's cold, but gets better when it gets up to running temp. Vacuum leak somewhere? Coil pack problems? The a/c hasn't been checked for freon leaks yet so I don't know if the problem is the electric cooling fan or not. Any help is good help.

 

could be the vacumm that goes to the heater/ac controler is leaking or broke or unhooked.

 

Thanks Craby

 

Does the A/C compressor even cycle on when the air conditioner is turned on? There is a switch in the line that disables the compressor if the freon level gets to low.

 

I think it's out of freon due to the car sitting a while. That's my next check!
Thank you!

 

Did you replace the O2 Sensor, or check diagnostics on it with a scanner?

 

I did replace the o2 sensor that the scanner showed. The egr valve looked good when I took it off but cleaned anyway. I replaced the broken plug wire and checked the plug for that misfire that the scanner showed and it looked pretty good. That plug wire that went to that plug was kinda carroded(sp) so it could be the coil pack right? I do still have a 1404 light still showing. The funny thing is that all the work that I've done to this car it still shows the engine codes. Engine codes is as follows: po155 replaced sensor---po303 replaced plug wire----po1404 egr valve bad?-----po442 no idea
HELP ME.................LOL

LOL.... I drove it without a gas cap for a few weeks cuz I lost it at a gas station. Then I bought one for the car but it doesn't quite fit right, cuz I don't think it's sealing just right. Oh geez that might be the freakin prob with that code. I'll try a new cap my friend. Thanks again for the heads up.

 

yep these cars are sensitive, lol and if u dont get them what they want u know about it. hope its a simple fix for ya.
