Thumbs down Not running smooth

From Idle to about 1500 rpms it feels like it is hesitating, after 1500 rpms it smooths out and runs great ?

Well I've got my work cut out for me, so I guess I might as well do them all as I have 212,00 miles on them.. Time for new injectors YES

mine was injectors also, that is what made me research the HSS, I had two noncontributing injectors, I have put 15,000 miles on since then with no issues, that is the big thing is coking of oil on the injector can cause the problems, although.....could be time to get stage 1's

Just a thought,

Couldn't this also be caused by a fuel / air leak in the lines say near the fuel pump and or bowl? Air in the lines combined with a loss of fuel at low volume?

Have you checked the valley for a leak?

Hey cOOn I did replace the wires under valve covers and I did have a burnt one, IPR seals and connector wires and there is no fuel in the valley. Besides the intake and exhaust mods I have nothing modified untill I get this probleme solved. Is it hard to rebuild the injectors?
