Water thermo sensor pic request
Having a cold start issue ever since I changed the spark plugs on my 91 n/a. It starts up, has a real crappy idle for a few seconds, stumbles, and dies. So I am pretty sure its the water thermo sensor that is causing this problem.
However, I can't find it.
I know its under the alternator, behind the water pump housing, but I just can't see it. I have all the accessories still, could that be why I don't see it? If someone can post a pic of where it is, that'd be great.
Thanks,

No, it's not rich enough. The thermosensor tells the ECU the water temp. If the ECU gets no reading then it defaults to something like 179 degrees (or something close to that) and it will not send enough fuel to the engine.
It works like a choke on a carbed engine (you guys probably aren't old enough to know what I am talking about). It enrichens the mixture so the car will start easily and run when cold.
Symptoms of a bad thermosensor are hard COLD starting and will not idle when cold.
