Fuel Injector Installation

I was wondering if anybody on this forum has removed and installed fuel injectors on a 2.2L Engine in a cavalier? If so, I want to know any tips or special reminders to keep in mind during the removal and installation. thanks a lot!

Just replaced O-rings on #2 & #3 injectors on my 96 Cav 2.2 last night. Don't make the mistake like I did (when use the screwdriver to pry out the bottom-feed injector) and dropping 1 injector under the intake in front of the coil pack... I couldn't get it out and luckily I have 2 spare ones and it is left there now:(

Relieve the fuel pressure by idling your car and pull the fuel pump relay until the car stalls...

You have to oil the O-ring before you can insert the injector if you have the bottom-feed type...

I am still cursing myself not being able to retrieve my dropped injector...

its not very hard. just take your time
