I need a little help figuring out why my car all of the sudden began having random misfires. I just got back from a 7 1/2 month deployment and the car has been sitting in my garadge the whole time. My fiance cranked it up every other week and thats it. When I 1st got back the car was running fine. Now, it keeps throwing codes for random misfires and it makes the car stutter and sound like a suburu exhaust. Nothing in the car has been changed since I left and it was running fine before I left. Any help would be apprieciated....

 

If it still has the same gas in it I would try getting some new gas for starters.

 

Change the oil, change the plugs and change the gas. Make sure you add a couple bottles of heet to your next fill up too.

 

I've already gone throught 2 tanks of gas to try and cycle out the old as well as change the oil. The spark plugs were the other thing that I'm about to change. When I went to the dealership on of the techs suggested it may be do to the fact that etheynol can create condenstation in the tank when it sits through temp changes for a long time. He thought possibly the injectors may have a bit of a clogg but he wasn't sure

 

Just give her a tune up since it has been sitting so long.. Run some injector/gas cleaner through it a few tanks, change the plugs and do the routine **** etc.. Take it easy on it for a while, don't expect to start it up and run the **** out of it!
