Engine Performance problem
2003 Chevy Silverado V8 Four Wheel Drive Automatic 105000 miles
I have noticed the rough idle for awhile and just now noticed when I start it up I puffs black? I have changed the spark plugs, changed the oil and I am going to seafoam it this weekend. It is hard to start sometimes, never in the morning it always fires right up after sitting. When I say rough start I mean, I turn the key over and let go it still tries to crank and wont start so I give it some gas while cranking itand its starts. Like a diesel with the black smoke haha, if you could giveme some ideas to check I would appreciate it, thanks
have the same problem?
