I just replaced a head gasket on a 99 escort with 175k miles on it. I got the new gasket and had the head cut as well. While I was at it, I got a new intake gasket as well.

I got the car all together and it runs fine on the road. However, when idling in park or drive, it sounds horrible!!!!! The car goes into a sort of "limp mode". The check engine light hasn't come on, but the car is awful. However, when I have the AC on, instead of dogging the motor down some more, it makes it run better.

As I said before, the car runs just fine when crusing on the road. Are there any thoughts of what could be wrong? I have unplugged the IAC, MAF, MAP, and TPS each individually to see if one of the sensors could have gone wrong, but the car acts the same for all of them.

This is a customer's car that I did and I have to get it fixed asap to return it. Any help would be great! Thanks!!!

check engine light on?

I would check the PCV valve, mine went bad on my 99 and my car had a high idle and check engine light because of it.

No, the check engine light is off. Also, the car is barely idling at all. I have done previous work on the car and the PCV hose has been broke and disconnected since I first started working on it. Now ,all of a sudden its important to the car?

I understand that yeah, its important. I'll go down tomorrow and hook up the hose. The reason that I said "it wasn't important" was that the car ran fine when it came here and the hose wasn't hooked up.

Any other ideas? I'll keep posted with what happens...
