Escort Idle Problems
I have a '92 Escort GLX and I have some idle problems. First of all the car Idles very unsteady. Lately, when I start the car cold the choke does it work until the engine is warmed up (not completely!) and then the idle problem starts. Sometimes it idles close to stalling and sometimes it's impossible to keep the engine running at a stop. After a while when the engine is completely heated up problems are over (I adjusted the choke well, I think, and seems to work right). The enige runs ok, not steady but good enough. Recently also when the engine is completely heated up it stalls as well at a stop.
I tried some things and this is what I found out:
I noticed oil in the air filter housing coming out of the hose that is connected with the valve cover and connected under the filter housing. While the engine was running idle I closed that hose and suddenly it runned much better. Though today it was a bit worse and the engine stalled again but when heated up it runs fine now. The hose that comes out of the valve cover is connected to a plastic T-piece that connect it to the air filter housing. From that T-piece is a litlle hose running to the intake. So to make thing understandable: The hose from the valve cover is running to a connecting piece of the air filter housing and from there goes a hose to the intake. The hose running from the valve housing is closed now.
Any suggestions what this idle problem I have may be??
