Chevrolet Repair: 95 s-10 Blazer Rough Idle & Gas smell, chevy blazer, leak gas

Question
I have a 95 Chevy Blazer s-10.  Possibly multiple problems.  I have been having problems with it starting and lately it is running really rough.  The Service Engine Soon light is on.  When I turn the key it takes a while to crank and when it finally does you can smell gas.  A small gas leak in the line?  The other problem is when I drive it, it runs real rough that when I come to a stop it makes the car move and will almost die.  Oddly a temporary solution has been to put gas treatments in each fill and it seems to eliminate the rough running, but not hard start.  Well I didn't have one this last fill and now it runs rough again.  I have replaced the fuel filter, replaced the spark plugs to champion truck, but the problem still remains.  Could it be related to fuel injector?  Any help would be greatly appreciated.

Answer
Hi Kristin, This is most likely your cpi fuel injector. This injectors can leak gas into the engine and make it very hard to start and cause a rough idle. I'm am selling one of these cpi injectors on ebay. I would have it checked out to make sure. The gas will end up in #2 and #4 cylinders. You can remove the plugs and smell for gas on them,also will be wet.
