I bought injectors (3yr warranty) off of ebay for $118.49

I bought NGK spark plugs, didn't like them and I might have fouled them doing the seafoam thing so I bought a set of AC delco rapid fires, putting them in tonight if it doesn't rain.

don't forget the replace the gaskets. I did the intake, throttle body, and EGR gaskets, and make sure the machined surfaces are perfectly clean, a vacuum leak can cause all sorts of other issues.

be very gently on the injector clips on the fuel rail, the rail is plastic and they'll snap right off (i broke 4 out of 8)

I did the cap, rotor, and coil since i was in there but left the wires since they looked pretty new and OEM AC Delco's.

you'll also probably break some vacuum lines so keep good track of where they go.

Also good luck getting that exhaust pipe off the intake manifold, I couldn't and gave up and did the repair with it still connected which was horrible, get that thing off before you do anything else, I tried penetrating oils, a torch, and breaker bars with no luck.

Do yourself a favor - buy injectors from five-0-motorsports.

I bought and installed "re-manufactured" bosch injectors on ebay, with a 2 year warranty. Those lasted like 3-4 months and the hard warm starts were back. I tried getting them to replace or refund them and got nothing. I ended up buying another set, from another seller..... had the exact same issue. Finally said f-it and put the new injectors in. They aren't really rebuildable, They can be cleaned, tested, get o-rings and some small parts but truly they aren't rebuildable.

While you are there you might as well do lower intake gaskets and FPR. Check out and possibly replace the ignition components as well.

Trust me, I tried saving a few $ by buying those injectors, it is just not worth it.....

I'm hoping I don't have to do that in 3 months, mine is an extra car. I think if it was my daily driver I would've bought the expensive ones. I would've just replaced the stock one that was leaking but everyone on the forums talked about how they were a bad design to begin with. That reminds me, fuel filter is next on the list for me...haha it never ends

Mine is not a daily either, it's just a weekend rig. I only put on about 10k miles a year. Hopefully you ended up with better luck than I did.
