How To: Injector Swap for 98+
I searched and searched and found a few different answers on how to change the injectors on a 98+ 2.2 so I decided to do a write up on it.
The only tools you will need are:
Then I took the intake assembly off starting at the throttle body loosening all 4 of the hose clamps down to the air filter (don't forget the one under the upper radiator hose on the left side). At this point you can take the 10mm bolt and PVC hose off the upper intake box and pull it out. After that is out of the way you can use the clip release tool to remove the 3 clips holding the intake hose to the fan shroud and pull this bazooka looking hose out of the way. This is what the clip tool looks like. You can now pull the fan shroud by removing 6 10mm bolts, 3 on the core support and 2 down on each side ![]() ![]() At this point it should look like this: ![]() Now it's time to deal with the fuel system. I started with releasing the flexible fuel line from the hard line that goes to the fuel rail. Start with taking the clip off the connection and unbolting the bracket that holds the line to the intake manifold. Then to make things easier I bought a quick connect release tool at Autozone for 6.95 and it only took a second to jam it into the connection and pull to release it. ![]() ![]() ![]() Now the tricky part. You have to get the fuel rail disconnected, so start by disconnecting the wiring harness at the fuel rail right on top of the valve cover towards the rear. Then you have to release the 2 10mm bolts holding the rail to the intake manifold. They are really hard to get to but having the right tools and taking your time helps, I used a bunch of different extensions and swivel joints to get them out. Here are pics of where the bolts are after I got the fuel rail out. This is the rear one between cylinder3 and 4 and the front one is between 1 and 2. They are kind of hard to see but they are the bronze looking bolt holes. ![]() ![]() There is a Metal plate on the rear of the valve cover that you have to take off also, it has 2 13mm bolts that go into the valve cover and a 10mm bolt on the back of the valve cover towards the firewall. Do not take the 10mm bolt out all the way because the bracket just slides onto it and you only need to loosen it to take the bracket off. This is the bracket. ![]() ![]() Once the fuel rail is unbolted you can carefully pull on the fuel rail until you hear the injectors pop out. You are ready to slide it right out the front of the intake, but you have to be really careful not to snag the injectors on anything because you don't want to damage them unless you are replacing them, but even then you have to be careful putting them in. ![]() ![]() ![]() Once it's out you can release each injector by unplugging the wire to each one. It comes off by pulling up on the blue clip until it hits the black tab and pushing on the tab to release it. ![]() ![]() ![]() Then you release the clip holding the injector to the fuel rail with a screwdriver, be careful because it goes flying when you release it, so make sure it is pointed away from you when you pop it off. ![]() ![]() Installation is the same as removal except I put a little vaseline on the injector seals and the intake hose that goes under the upper radiator hose to make everything slide together a little easier. This is the lower intake hose I was talking about putting vaseline on. Do not use too much because you don't want any residual in your intake or injectors. ![]() Good luck with it, and feel free to add any other info that will help people in doing this. You are liable for the work that you do so be careful and take your time. |

re: How To: Injector Swap for 98+
I am chasing a misfire. I decided to swap the injectors from cylinder 3 to cylinder 4 to see if the misfire moves with the injector before I went and bought a new one. |

Re: How To: Injector Swap for 98+
I'd suggest using new o-rings, they are like $10 for all eight. Just be sure you dont mix them up since they are different for upper and lower.
I'm a fan of doing jobs once. I had to replace my injectors at 210K miles, i think the original o-rings had enough. |

Re: How To: Injector Swap for 98+
Great writeup. I always thought you had to take the intake manifold off to get to those injectors.

Re: How To: Injector Swap for 98+
man this is a blessing because I thought you had to take the intake off as well!! and... I am possibly getting ready to do the same thing as I am having a misfire and my computer has said that its in injector #4, already have the injector.. but I better go get those fuel line removal tools that I will probably never use again! lol
Thanks orangedime |

Re: How To: Injector Swap for 98+
I also believed that you needed to take the intake manifold off to do the swap. But when I looked at it, I thought "why wouldn't it just slide out the front if I move everything out of the way?". I'm glad I tried it, hope this helps you through the process. Don't buy the injector until you swap them and confirm that it is the injector, no reason to spend $80 on a part if it's not going to fix the problem. |

Re: How To: Injector Swap for 98+
does the fuel pressure regulator fit thru the intake manifold?
or do you have to remove it? how does it come off? i removed the torx screw but i didnt have any luck getting it off the rail but i was reluctant to pull to hard or pry. |

Re: How To: Injector Swap for 98+
The flex fuel models dont have a regualtor on the fuel rail...its in the fuel fuel sensor located right near the coilpacks
If you really need a picture I can take some this weekend...I got all kinds of fuel rails at home |

Re: How To: Injector Swap for 98+
I ended up using a light dab of motor oil to lube it up instead of vaseline.

Re: How To: Injector Swap for 98+
I replaced my injector and it didnt help.Took it to the dealer and they took the intake off.They ended up saying the injectors wasnt bad but the computer was..I guess thats a way for them to make some money by taking it off..

I do not have those little blue clips and mine is a 98. Mine are metal and they like to break.
