91 Loyale rough starting
Posted 13 January 2013 - 02:41 PM
Recently it has become very difficult to start. You have to bury the accerator pedal and once it catches it runs very rough until it warms up. Once it warms up its fine.I have replaced the fuel filter and checked to make sure the fuel pump is working(it is).
The only other thing I have noticed is once it catches and starts to run from a cold engine you smell fuel from the exhaust until it warms up.

The temp sensor near the therostat is only like 20 bucks so if thats the correct sensor I 'll start their first and replace it.
This Loyale wagon was gift from my Uncle, it was his "extra" car and was garage kept all its life until a few years ago when he gave it to my wife . And it just went over 100K.
This cars a keeper

The IAC is located on the throttle body and has the hose going between it and the intake boot. Soak some sea foam in that piece. There are plenyt of write ups for servicing the IAC

What you could do as well is unplug the CTS (green, two wire sensor just under the thermostat goose neck) and see if it changes how it starts/runs.

The sensor is a little pricey but from all the threads in forum's I have read it sounds like a strong possibily that its that Sensor.

For days and I'm just getting over the flu.
Does any one know if the TCS on other year subarus
Will fit my 91? I can't imagine a different Sensor for every
Model and year. But I'm headed to the boneyard Monday to look
For a Subby.

It was the Idle air control valve1 replaced that and its running pretty well. Still likes to be warmed up before she's driven though.
Now to figure out what I should go ahead and replace before it fails....

That's an old Sube.... I always let mine warm up for a few minutes, especially in colder weather where I've let it go until it idles down on it's own before moving it.
Run beautifully, if you just let them 'wake up' at their own speed.
