Re: Injectors
I have a 1991 350 TPI. I think it's the L98. It runs really rich now and has a rough idle all the time and I have these injectors sitting around. So is it worth the hassle to swap out?

It would make more sense to find out why it's running that way. Is the SES light coming on?
Weak O2 sensor is probably the #1 reason for running rich. Rough running typically ignition or compression related. Could be a dirty, leaking, or electrically dead injector, though.
