Coil packs
So I’m putting my coil pack back in after new intake manifold and I read somewhere that the coils have to go back in the same spot as they were before I took them out.. is there any truth to that, or can I just pick a hole and put them in??
also do the coils packs have to be torqued down?
thanks casey

I did buy new boots and springs for my cop... I also bought new pigtails that plug into the top of cop off amazon for $12.99 if anyone cares lol. Because 4 outta 8 were broke, but my question is when I instal new ones it’s as easy as line new one up with old one and make sure I solder the right one together. From what I can tell the cop wires don’t cross to the pigtail at all. Just straight on straight.
thanks Kc.

The main reason is for misfire diagnosis. If you were seeing misfires before replacing the plugs, putting the coils back in their original positions would allow you to determine if the coil is at fault.
Typically the coils would be swapped between cylinders to determine if their faulty, but if the plugs are worn enough, that’s not always conclusive.
Also if it’s just the plastic connector that’s broken, you can remove the terminals from them and swap the new connector in without splicing the wiring.

Old clip
New clip and they snap in and stay connected
now it’s time to put my new injectors in. Is it easier to take the fuel rail off to do them? I already have my throttle body taken off.. or should I just take the 4 bolts out and swap them out quick?
thanks for all the help with everything..

I see ACCEL coils in your photos.
A no-no from experience a long time ago that cost a lot of money in related damage..
Your going to end up replacing them.
Look at Mode 6, test 53 for the cylinder/s with the misfires.
This is the hint those coils have to go.
Chinese mfger, not good.
Good luck.

those coils have been in for 4-5 years now.. I take it they cause misfire? I haven’t had a misfire until last week because the intake manifold didn’t get torqued down right which was jack fault lol.. and taking it apart again I noticed broken fuel injector, broken coil pigtails, and I small rip in rubber boot and I bought 8 new ones and I used dielectric grease when putting new boot on.
And I have this scanner coming Saturday. I never herd of mode 6 before until a couple days ago but it seems like it help a lot.

Once the o-rings are on the injectors, a little dielectric grease helps them slide easily back into the rail and the manifold. Twist each one back and forth to help them seat and torque the rail bolts to 89 in-lbs.

You mentioned your intake wsnt torqued down correctly........Chances are good that you got coolant into the intake ports........How long has this engine run since you replaced the intake? sometimes this takes a while of runnning to burn off any coolnat that got down in the cylinders. And that would also cause a misfire
