88 RX will not idle when cold.
Posted 24 September 2003 - 04:01 PM
First, let me introduce myself as this is my first post. My name is mike and i've recently purchased an 88 RX 3 door. I'm no stranger to subarus as i've owned an SVX for quite some time and I work for a subaru dealership. I've had my SVX for about 3.5 years and I'm a moderator over at the svx world network forum (www.subaru-svx.net). The RX I got was quite a find. I got it from the original owner and it came with all the service history and even the original window sticker! She took very good care of it and always garaged it!
Anyway now I should get to my problem.
The car starts right up and revs up as normal. Then after about 5 seconds the rpm's drop quickly, and the car stalls. This can be avoided by pressing the gas pedal. Once the car warms up (must hold the gas pedal down to keep the revs up for about 5 mins, very annoying) the car will idle just fine when you take your foot off the gas. You can drive the car normally then and there are no problems. Once the car sits long enough for the engine to again cool off, the problem returns.
My original thought was that it could be the IAC. I removed the IAC valve and cleaned it out with carb cleaner per the advice of a tech at the dealer where I work. This had no effect on the problem.
Any help would be GREATLY appreciated. Thanks to all!

You are close tho. Over beside it, on the intake manifold, with a TWO wire connector, is the coolant sensor for the computer. It has a rectagular connector.
The coolant temp sensor is more towards the passenger/right side of the engine, again, on the intake manifold...the lower part of it.
