Low MPG after storage - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

I was wondering if anyone had any ideas on my issue. I stored my car in December for the winter. I avergaed around 15-16 mpg. Pulled it out of storage in March, changed the oil (Mobil 1) and cleaned the filter and TB. Since getting it out I notice I am only getting 13-13.5 mpg. Drive is the same every day (short commute) and my driving habits did not change. Any thoughts?

Did you do a fuse pull?

dcamaroguy · 05-22-2016, 10:46 AM

No fuse pull. Didn't think I had to because it has a custom tune and the battery was disconnected while in storage

Make sure mice didn't find their way into anything

Rest the MPG-

then you dont need to do a fuse pull as both tables are the the same tune. did you put fuel stabilizer in it and it has the old gas in it? that can do it. How bad was the tb. if it was bad the car has to relearn. you should clean the MAF with MAF cleaner too. clean your MAF put a couple of tanks through it then check it again.
to clean the MAF get a can of MAF cleaner and follow the directions on the can. do not wipe it or touch it with anything other than the cleaner. MAF has to be warm when you do so take it for a short drive. get your tools ready to pull it and open the hood shut the car off then pull it and spray it.

If you disconnected the battery, your avg mpg reset. When you pulled the car out, changed the oil, and all that goes with pulling a car out of storage, my guess is that you probably spent more time at idle than you did when you put it away. Clear the MPG again, and drive as normal, it will get back to where you were eventually.

I have run about 3 tanks of fresh gas through the car since taking it out and I reset the fuel mileage at each fill up. The TB was pretty dirty so I will give the MAF a look this weekend. Thanks for the tip.

walmart has Techron fuel injector cheaper than auto zone or advanced auto. Get some and use it. After that tank use Lucas fuel injector cleaner and you should be good to go. It doesn't take much to clog up these new injectors.

I only get about 250 miles out of a full tank :(

If your girlfriend put you in storage and hung out with a different guy for 4 months, you'd probably be kind of upset too...
