Ran Accross this thread, forgot about it... I did do a compression test today. All were 350 to 365 with the exception of cylinder 3 at 340 PSI. Still within about 7% of each other. I had it running without the VC's on and while watching scangauge with Mass Fuel Desired (MFD) I unplugged them one at a time. Hovering around 6.5 Mg per Stroke and when I unplugged one it would go around 8.0 maybe slightly less, except for 6 and 8, they were not hitting as hard. The numbers for them was more in the high 6's to low low 7's with injector 5 hitting only a little harder... I did notice that Injector 8 said LL on it and was the only reman, its been replaced the latest back in 2010 trying to get it to pass smog here is cali... All that and I dont remember seeing if they were AB injectors
Would I be better off replacing 5 6 8 injectors or just replacing them all, the injectors are all 9 years old (No 8 is 5) but only have about 150K miles on them. I know 6 and 8 fight for fuel but at idle they're not in need of much flow and I didnt think it would make them both weak as much as just make 8 be weird....? Thoughts on the matter would be greatly appreciated.
