[92Legacy LS/FWD - engine sputter/misgfire when light load/cold or wet]

Is there a pointer somewhere on where the Coolant Temp Sensor is and how to replace it? Is this something that could be done by a relatively green DIY'er? (I used to work on old Yamaha bikes, but this is a different level of complexity).

 

Thanks in Advance.

Thanks for the advice.

 

The problem only occurs when I start the car. It usually persists for about 10 minutes or so until the car is warm.

 

I agree that I don't trust the mechanics advice on these issues as well.

 

I'll post follow-up soon.

 

Thanks again.

Ok,

 

Let me start by saying I am a auto-mechanic lightweight.

 

I recently inhereted an 92 Subaru Legacy L 2.2L. When the engine is first started (cold), it idles fine, but under light load the engine sputters, misfires. When I floor the accelerator, all the issues go away, but are there until the engine is warmed up. Once the engine is warm everything is OK. Also, when I drive in the rain, the problem rears its head, but not as bad as when it is cold.

 

I had the spark plugs/wires replaced. Put fuel injector cleaner in the tank over the last 3 tankfuls.

 

I took it to 3 different mechanics and they have told me several different things.

 

1) Need to replace injectors (2 are bad, but other mechanic disagrees)

2) Replace Cats, they aren't working well until they are warm.

3) MAF

 

I am relucatant to spend a lot of money on the car, since I own 2 relatively new cars. This car is a great city car, and I'd like to keep it if it's cheap to own.

 

Thanks for any advice.
