Number 8 Injector Question

I took my early 99 into the dealership today because I've had an occasional rough idle and random missing at times so I ran a contribution balance with my AE and saw number 8 came up. I didn't have time to mess with it so I dropped it off to them and they checked all the wiring above and below the valve cover but of course it didn't act up for them other than the contribution balance still showed number 8.

This is where my question comes in, when I picked the truck up they told me they suspect the injector is beginning to stick on occasion and will need replaced in the near future but to wait until it gets worse. I asked them for an estimate to replace the injector and a mild heart attack followed. My local dealership wants 900 dollars to replace one injector. They say a single injector books 500 a piece through them. I was at a loss for words and told them I would most likely take care of it myself. From what I've read I need a single AB injector (is this correct?) but I don't know where to get a good priced and good quality injector, and how hard is it to replace? This is my daily driver and I can't be without it.

Sorry for the long post, and thank you for the help

Thats rediculous since you can buy brand new stage 1's for $1500. I'd say they padding their pockets. You should be able to pick up a reman injector for $150-$200. Make sure though you specify its for the no.8 cylinder since it takes a special one. Good luck on your search.

That was another question I forgot, does the number 8 still take a long lead on an early 99?

Oh and if you do it your self the bolt on the very back of the valve cover is a son of a bi*ch to get on and off. Plus if you cant locate the drain plug for the oil you will have to suck every little bit out of the cylinder when you pull the injector or you will end up bending rods. If I remember correctly the bolts on the valve cover are 14mm and another one of the things you have to pull off is 10mm. The wire harness you have to pull may be that but if i remember correctly it is smaller then 10mm.

Does not have to be a "special" injector, they did this to try to stop engine knocking, if you buy a set of aftermarket or reman injectors all 8 are the same.

yes since it is located at the back of the fuel rail so it doesnt get all the fuel it should so it has the lead on it to get more fuel

Do you have a gray recall style CPS? Mine did that too with the gray CPS. Swapped back to an old style black CPS and my truck passes the contribution test on all 8. Some trucks fail #3 & 8 with the gray CPS but not the black
