Sounds like an inexpensive fix and I will try it! I was wondering what Seafoam is? Oh yeah, I have 145,000 miles on my 1995 Subaru Thanks!

I had the codes read and they were PO130 Front Oxygen Sensor circuit Malfunction and PO505 Idle control system malfunction. What should I do now? McWalter

What do you mean by getting the codes pulled at AutoZone? Do they have diagnostic computers or code readers?

I have a 1995 Subaru Legacy wagon and I think my Throttle Position Sensor my be bad. For a couple of weeks when the car would idle it would flucuate between 700 and 1500 rpms not one or other but irradically. Then once the car was warm and I would pull up to a stop sign and sometimes the rpms would drop down to 500 or just below and of course the car was running a little rough. Now the check engine light has come on. Bummer I first checed the idle control valve and it was working properly. I would unplug it and the rpms dropped and plugged it back in and the rpms came back up. I would like help on how to test the Throttle Position Sensor. My book tells me to test the terminals for ohms resistance depending if the throttle is closed or open. Terminals 2 and 3 throttle closed 12 k-ohms and throttle open 5 k-ohms. Terminals 1 and 2 throttle closed 0 ohms and throttle open 1 mega-ohm. I have tried this test and my ohms results did not match. I was reading a Chiltons repair manual and do not trust it. I would like to know more ways of testing it? Thanks!
