Engine troubles with my 2006 Mustang GT
I put some fuel stabilizer in my car before I left to Iraq (3 1/2 months). The wife cranked it weekly and it ran low on gas. She added 87octane. I freaked out a little. She put octane booster in. There was probably a 1/4tank full. I get home and crank my car. White smoke for a little bit and then it's gone. My car runs like its on 7 cylinders. I put 93 oct from Chevron in it and drive it for 15 minutes. Still runs like crap. Any suggestions? I have weaponX COP's, brisk iridiums and magnacharger.
