Question about 1995 Chevrolet Blazer
1995 chevy s-10 blazer 2 wheel drive with 4.3 vortec .It ran fine until a few days ago i noticed it was kind of jerking when i started it up, so i drove it to work and it ran ok at 55 or 60 mph but when i sat idle it would be rough. Now i take it to my father in laws so i could get his opinion (it uses over 6-7 gallons of fuel the 16 mile drive to his house and i usually get 17-20 miles per gallon) and seen that it had been leaking gas so bad it was all over passenger side of exhaust manifold and frame,he said it could be a bad spark plugs so i changed them. didnt fix the problem.The suv has 160xxx miles and has always had the oil changed on a regular basis and proper maintnance.What else could be wrong with my suv. All advice and opinions appreciated.
Check charcoal canister - map sensor and oxygen sensors.

It could have a fuel leak inside the intake. These are good for fuel lines in the intake leaking. To test for this the only thing you can do is take off the upper intake and then turn on the key. If it has a leak you will see it with the intake off. Check the two big lines going to the injector and the small pintle lines, especially the ones on the drivers side. They tend to rub holes in the two big lines. Also check the vacuum hole in the fuel pressure regulator. No has should come out. Also while you have the intake off, pull off the EGR valve and check to see if it has a chunk of carbon stuck in it holding the valve open. These are all common problems.
