1995 Chevrolet Other

1995 Other Chevrolet Models V8 Two Wheel Drive Manual

I have a 1995 Chevrolet 1500 and for a while now I have been noticing that every time when I'm pulling up the drive way or just slowing down at a stop light and stop sign my truck hesitates really bad it sounds like it wants to turn off and it smells a lot like carbine monoxide. I was told that it could be a censor. Now, a while back my husband did put a new censor that is located under the hood where the cobarator is located and we have done a tune-up and spark-plug & wire change and fuel pump change, we also put a new muffler but we haven't found the problem. I really don't know what it could be. Can you please help me?
