Just put in a crate 350 and it acts like it needs more gas can you help with this? I am using a stock 305 TBI with a 305 stage II chip. I want to keep the throttlebody injection. Can you change out injectors in a throttlebody?

 

pretty easy but you will need to get a gasket and o-ring kit to do it, the o-rings on teh injectors tend to distort once used. while you have the top of the pod off it woudl be a good time to do the diy afpr too, since it is already apart.
first undo the battery and loosen the fuel filler cap[ to relieve the system pressure and get to work:
1. unplug the injectors
2. unscrew the torx bits that hold the top of the injector pod
3. lift the top of the injector pod straight up
4. with a flat head screw driver pry the injectors straight up(pry against the bottom of the little mushroom caap on top of the injector) once the injector is oput you wil see there si an o-ring at the top and one at the bottom of the injector.
5. put the new o-rings into their places on the top and bottom, just place teh lower o-ring where it wants to rest when you drop it into the pod, do not press it all teh way to the bottom(the injector will do that for you)
6. place the injector so it rests on the o-rings and then squeeze it down by using two channel locks plyers, one on each side. squeeze it using the bottom of the pod and the lip of the injector. you will fell it slide into place and stop when it is seated.
7. same thing for the otehr injector
8. put the top of the pod back on and plug the injhectors back in.
9. plug the battery back in and close the fuel filler cap
10. turn the key tp the run position and check for leaks
11. if there are no leaks, start teh car and let it warm up, once warmed up a little rev the motor a few times and check for leaks again. if there are no leaks then turn the car off, go over the torx screws to make sure they are all tight and yer done.

hope this helps

later
