So I started my car this morning with no hassle, except it takes an extra second or two before the engine sounds ready to drive. I drove it twice today, the first time was fine, but tonight when I was driving, I was coasting with my foot off the gas and the engine killed. it started right back up again, but this is scary. I did replace all my injector rings recently, and didn't have a torque wrench for my intake manifold. If I under tightened the intake manifold, could it be to blame? I have also cleaned my IAC about 4-5 months ago. Could it possibly be dirty again? Should I get a replacement, or just clean it again?
Thanks for the help, you guys are the best resource around.
P.S. the check engine light doesn't come on any more, and I could use an oil change, its about 3000 miles since last one
