Make sure that your engine is going in to closed loop.
Make sure that the rest of the info on the scan gauge looks correct.
After that, do a tune up on the car, transmission flush, spark plugs (compare them to each other), air cleaner, pcv valve, check your timing, check brakes and wheel bearings.
Is your new Geo a 3 or 4 cylinder engine? hatch back or sedan?

4 cylinder hatch back Suzuki Swift. How does one go about checking the engine temperature? Can the scangauge do that? Is it FWT for the temp? How long should it take for the engine to reach optimal temperature?
How do I ensure that the engine is going into a closed loop? What does that even mean, and why is it important?
Also wanted to mention that I very rarely get the infinate fuel reading of 0.0 LHK; even when coasting down a hill I'm often still at 2.0-3.5 LHK. Related?
I have two engine codes that pop up now and again but I cleared them recently (the mechanic said they were not important issues). I remember I think that one of them is P0036 "Heater Resistance Out Of Limits" according to engine-codes.com
