Default New injectors?

How long do they last? I have no idea how long they've been in there. And I am still on the F. I Iearning curve. So last season first test session, we have a starting line stumble never had before After about 3 runs it was gone. I was kicking myself because i remembered I had put some super unleaded in to move the car around during the off season and i was sure they were probably sticky from setting several weeks pump gas in it. So I made sure this off season always had R11 in it . And we started it every now and then. So first test session week ago stumble again . So im thinking about just putting some new ones in.

If you have even the slightest doubt send your injectors out to be serviced or replace them. Don't wait until you kill the motor....

I agree with Gump to have them checked out, but look at them closely and carefully when you remove them from the injector rail to see if there is any trash on the top of the injector. Your fuel lines may also be deteriorating if you have no idea how long the injectors have been in there. It might also mean your fuel lines are super old.
