Thanks for your response. Check engine light only came on for about 30seconds when idling and revs jumped up for a couple of seconds - light is no longer on. I'm presume it's OBD I but not 100% sure. I'm leaning towards Coolant Sensor at this stage..have had a couple of instances on really cold mornings when I haven't let the engine warm up - the car has struggled at low idle (at stop signs/red lights) where the car has effectively stalled/lost all power (I'm guessing probably flooded engine). I took it into the mechanics to do a diagnostic scan and they reckon no codes came up. Possible dodgy mechanic as I had a mate plug in 2 different scanner tools and they couldn't get any power through the dash to the scanner?! Not too good with the electrics/computer side of things unfortunately. But done all the mechanical checks and can't identify any issues elsewhere that would cause it.

Hi Guys, I have a 1995 Subaru Liberty Heritage, 2.2l Auto, 190k on the clock. About 3 months ago I had a major 6year service on it - about a week later the engine light came on, took it back to the mechanic and they changed an ignition coil and the alternator. Recently I have been having an issue when I drive on the highway - the temp gauge appears to fluctuate - it will go up near max but just as quickly comes back down to normal temp again. A couple of days ago I came off the highway and was idling at a red light - the revs jumped from the normal 500 to over 1k for a couple of seconds. The temp gauge was showing at almost max (car did not appear to be overheating though and no issue with the coolant level). This has happened on a couple of occasions - always seems to be after I have driven on the highway (which I only do approx. once a month). Also a few days ago sitting at a red light the revs jumped up for a few seconds and engine light came on for about 30 seconds (engine light not on at the moment). Any ideas of what could be going on?? Would really appreciate it! :-)
