The Blazer has a code for a misfire on 5 or 6 (my friend, the owner, said it was a while back and I havent run a scan on it yet). It is losing coolant and the oil smells of gasoline. There is no signs of coolant in the oil, however. Someone told him it could be the fuel spider, I just can't figure out why if it were the spider where the coolant would be going. The Blazer will run and move, although it does smoke a lot.

Any advice is greatly appreciated. Thanks in, advance.
