Mustang stuff

The miss is mostly noticeable at idle, when driving you cant notice it. The car has a tune. I meant pulling the rail with the injectors still attached if you can do that. and i used the champ. rc12yc plugs. im thinking a leaky injector or something along those lines because in the morning i see a little more smoke than normal, not a crazy amount like a head gasket. I can also smell like raw fuel from the exhaust and a gasoline smell in the engine bay sometimes.

If you pull the rail with the injectors attached to the rail still and turn on teh key, you're going to shoot teh injectors out of the rail, because there is nothing there to hold them under the fuel pressure. If it's just a light miss it's probly just the mods and tune. ALmost every modded car with EFi i've seen has a slight miss to it at idle. 94 95 computers are worse than most others also. Smelling a little rich at idle seems to be normal to me, but raw fuel smell would concern me a little. Moniter fuel pressure, if it leaks down within a few minutes of turning the engine off then you may have a leaky injector.
 
What i meant was that pulling the rail with injectors attached but not turning on the fuel system just to see if anything leaks down. I did the fuel pressure test and there was no loss of pressure after it was shut off, i waited for like 5 mins. and this miss just started happening for the last 2 months.
 
or go on ebay i bought a whole box of em for my old car on there for 10$ lol(couplers from tb to elbow)
