ouch... one of my bolt was really tough to get it out too.
you can take off the cover, first remove the intake arm and the box mechnism.
then you remove the black plastic intake that sits on top of the engine.

after that you should have more room to work on the backside... but still, i don't think it would be wise to dremel it out with the cover opened up like that, not to mention the space is still pretty tight even after you removed all that stuff.

best is to take the head out, put it on the bench and carefully take out the bolt?

my Fit still misfire at idle randomly sometimes... still don't want to replace the coilpack, so expensive... ugh

 

Unless there's a reason to replace the coilpacks, I would just clean them. That's what I did and the hiccuping is gone. To clean, just pull the boot from the headpiece and use needlenose pliers to get the spring on the headpiece side out. Take some rubbing alcohol and clean everything with a Q-tip. Let dry completely, then apply some dielectric grease on all of the contact points. Reassemble, reinstall, and you are good to go.

 

Hi, do you mean to pull the coilpack out, flip it upside down and PULL the spring out? Or do we need to unscrew it or something? Just want to make sure before i start pulling it out, don't want to screw it up.

Thanks

 

No. I was not able to remove the spring that makes contact with the spark plug, so I put some dielectric grease on the end of a Q-tip and transferred the grease onto the spring that way. There was no visible corrosion on that spring anyway.

Remove the coilpack from the engine. Grab the shaft with one hand, hold the headpiece with the other, and pull apart. You may have to bend the shaft back and forth while pulling. When you separate the two parts, you will see a second spring coming out of the shaft. That spring was coated with a white powdery substance that I cleaned off and it does come out if you grab it with needlenose pliers. You will see a fuse looking thing on the other end of the spring. On the headpiece side, wet a Q-tip with alcohol and clean the nipple. Dry completely, and apply dielectric grease. I cleaned and applied grease on all of the contact points (both ends of the fuse thing, both ends of the second spring, the nipple, and the 3 prongs of the connector).

 

Ah cool, thanks. I thought the shaft was inseparable with the top head piece.

 

I thought so too, but it's held in by a rubber boot. The rubber is soft enough to stretch to get the shaft out, and I think that may be a part of the problem. Other posts have suggested that you get moisture inside that causes the corrosion. I have not seen the newly-designed coils, but apparently there are ventilation holes now. But before I spend $65 each on new ones, I'm happy to spend the hour cleaning all four of the old ones.

 

thanks for the replies guys.

code - i managed to hold the coil in place. i got longer bolts for coil 1 and 3, held them in place by tightening a nut, and used a mending plate across coil 2. tighten bolts on coil and 1 and 3 to create pressure to hold down coil 2.....kinda like a ghetto battery tie down.

kinosh - thanks for the tip, but i opted to replace the coils....3 of the 4 were brownish and had cracks on the rubber boot....so i decided to get 4 new ones. only one coil looked like it was brand new.

NOW....here is my further problem. the reason i considered new coils was because the car's RPMs would go so low at idling that the car would turn off. if i were to drive and hit a stop sign/light, the RPMs would drop so low the car would shut off. i will search the forums to see if anyone else had this problem even after changing plugs and coils to see if they came up with a solution. with that said, has anyone encounter this problem? granted....this problem "goes away" after warming up the car for about 15-20 minutes....yes....its a long time....i know. any idea or clues to solving this mystery would be very appreciated. Thanks in advance guys!!

 

I am not sure if this apply to the Fit, but I have an Integra (for about 12 years and going), and Integra have this common problem with the Fast Idle Control Valve, that could get clogged/dirty or not functioning properly over the years. If the Fit has similar mechanism, i'd suggest you take it out and clean it.

Because it sound like when your car is cold, the valve doesn't open up (when it opens up, more air goes it, hence your rpm goes up when you first start up the car).

 

Off topic... Just had to say your Handle/Username caught my attention...

 

hearing that.....sigh....makes me feel like i did my job....i got your attention somehow, lol.

code - thanks man...i will look into that. its frustrating when yuo think you have the problem nailed and its something else instead. my baby has 120k on her.....so installing new coils didnt "hurt" me. the fact that i still have this rough idle/engine turning off problem irks me more. i will continue to search and tinker with her....i will post my findings once - and if - i manage to fix the issue.

whoops....they got those links blocked here at work....wtf. Thanks Subie, i will check out the links as soon as i get home.

 

Coz you're supposed to be working... not ...

 

No he pasted wrong links i think. We don't block anything here at work, and i get some XML data instead of a page.

edit: shit, is some stupid viglink crap.

 

@code, you got it. Somehow the links get corrupted when posted but ok on my end with preview... I tried...

 

Is this forum, they put in some viglink ad api crap... clicking on the links from my gmail is fine though. I got your links in my email notifications.

 

I am at about the same point on miles as you and I have the same issue with the car shutting off when it is cold after first starting up when you let off the accelerator when coming to a stop. I had read elsewhere in the forum that this could be solved by adjusting the valves. I haven't had a chance to adjust mine yet and I was looking at this thread trying to decide whether or not to mess with the plugs and coils at the same time. I'm not having any issues with misfiring or loss of power under load so I may leave them alone for now. Looking at doing the valves this weekend so I'll let you know how it goes.

 

geek - any luck with the adjustment? i was going to attempt it this weekend, but didnt have to time....i'd like to allot myself at least 6hrs - i want to take my time as it will be my first time - but couldnt get it this weekend with holiday shopping and putting up stupid decorations. i was hoping to find a DIY video so i can see what im getting myself into...but havent found any. i've just been reading the links provided by Subie....its better than nothing, lol.

 

Thanks for pouring salt in the wounds, it is still Monday morning, the weekend is a long 5 days off. I am shooting for the upcoming weekend if it ever gets here. I replaced the catalytic converter heat shield this past weekend. I got tired of hearing the rattle. I will let you know how it goes. I've read the post and got all the necessary stuff together. Doesn't seem like it will be to hard to do. The hardest part will be getting enough clean space in my garage to get it in so I don't have to do it in the driveway.

 

oh shyt....my fault bro....i should check the dates on these things, lol. i didnt notice your post time. i found this in another fitfreak thread - https://www.fitfreak.net/forums/fit-...-download.html - i cant download it at work - site is blocked and not sure if it still exist, so i apologize if im giving you a dead link.
