CHEVROLET SMELL

I Just Got My Blazer Back On The Road It Sat All Summer And Now I Finally Got It Inspected And All That Good Stuff And While I Am Driving It...

My Car Has Been Starting To Make Noises In The Last Two Weeks. It Almost Sounds Like The Alternator, When It Goes Out, But I Know Its Not...

What Causes The Engine To Shake, To Barely Accelerate, And To Cause The Exhaust To Smell?

I Have A Potent Odor Of Exhaust Or Fuel In My Cab And It Only Happens On Start Up And Idle. Do You Have Any Ideas On What The Cause May Be?
