I live about 10 miles from work, mostly highway. Still get about 29-30 MPG with the 2.4L engine and a manual transmission. Still love my car.

2001 Pontiac Sunfire;bad gas mileage by moe75

I have a 2001 Sunfire SE 2.2 and wondered if anyone out there experiences poor gas mileage and an erratic gas gauge? I did a recent tuneup( plugs,plug wires, air filter) and I only get 18-20 miles per gallon. Its really seems to burn the gas. No matter if Im idling,in the city, or on the freeway, it chews it up. I have 125k miles on it and it seems to run pretty decent. Anyone have any light to shed on this?
Thanks

I have the EXACT same problem as moe75 ( also recently did a tune up, mileage is 128k miles) - anyone know what may be causing this poor gas mileage? Thanks.

erratic gauges by argus1

All of a sudden my temp gauge (2005 sunfire) 2dr would not go back to zero when engine is off - - so when engine is os on, the needle was in overheat range. It continued to move higher and now reaches all the way over to Tach and keeps tach needle locked. It stays with way whether engine on or off. Any suggestions? Do I need a new instrument cluster?
Also if I get a used gauge cluster, is the cars milage picked up from PCM and transferred to the newly installed cluster? Thanks

Can anyone post they're milage there getting per tank? I'm in Ontario Canada and I'm getting not to bad hwy milage but in the city I'm getting maybe 400 km (248 miles) a tank. When I first got this car, I could get at least 450 a tank but now I watch the needle get within a quarter of a inch before it comes near 400.

My brother had the same problem with his 96 firebird formula. Try a new sending unit or ask your repair shop if a sending unit would fix it.
