Ignition Problem: Help with diagnosis please!

[JasonGilholme]

Hey guys,

Hoping you could help with a problem im havin.

Heres the symptoms

Intermittent lumpy idle
Intermittent hesitation on acceleration (generally high load, low RPM)


Things done so far:

Replaced Leads with Top Gun 8.8mm
New plugs


When idle is playing up i can push/pull the leads and press on the dizzy cap and the problem goes away. it will come back after a while once i'm driving though.

I've ruled out things like fuel pump/filter, main relay, air filter, injectors etc mainly because everytime i fiddle with the dizzy the problem goes away.

Heres some pics of the cap/rotor button:























If anyone can notice anything thats wrong just let me know, or if anyone has any other ideas as to what the problem may be/what i should replace etc. just post it up.

Thanks for the help guys.

EDIT: Just noticed in PIC 6 there looks to be a crack to the bottom left of the silver thingo (have no idea what its called lol), possibly a casting mark though. And also in pic 1 is there meant to be a cap over the spring or not?

replace the cap and rotor. ITs a cheap fix that will often fix minor idel and timing problems. I replaced a rotor recently , that looked 100% ok on te outside. No cracks etc. but it did not transfer power to the leads and thus would not start the car.

There isnt a cap over the spring , thats how it sits over the ignition coil.

thanks ben.

Replacing the cap/rotor was my next logical guess.

[bennjamin]

ive got a spare igniter unit (ICM) and ignitiion coil to suit your dizzy if you need it.

anyway change the cap and rotor with TEK / oem parts and that should fix up your issue.

A good idea while your at it is possibly to change to an aftermarket external coil cap and coil. just a thought do avoid future issues with the weak honda coil, we all know the oem coil isnt the greatest lol

Goodluck

Ben, where to you source you ignitors from?

be carefull when you tighten the cap back on i've heard the bolts can snap easy

[B18cEG]

You can get a champion replacement coil from repco (i dont know if u have repco over east) or any parts store, the champion ones are pretty good. About $90

[JasonGilholme]

B18cEG: i think i'll stick with the OEM gear for now. If the coil does decide to go at a later date i will think about upgrading to a external unit. Probably an MSD as its a proven unit.

Darryl: Yeah bolts do snap easy don't they...

Ben: Any other places apart from honda to get good quality replacement parts? I like the idea of shopping around for prices.

[B18cEG]

Pretty sure any parts store can offer something like champion or bosch replacement coils and caps.

i disagree.

the OEM "TEK" honda coil is a once in 10 year fix. 3 of my EGs coils failed at almost the exact 10 year/180-200,000k mark. Thru hard driving or daily.
My point is honda make fine parts for their cars. Aftermarket will often fail long before honda 9this goes for ANYTHING)

Replace the ICM and coil , with honda parts if you can.

Sorry bud, i think u misunderstood what i meant, i didnt say they fail easily, i was saying they are weak not poor quality, weak compared to external coils in terms of spark energy/current and voltage, i know the oem coils are great and i stick by honda 100% but i was talking about an upgrade not just a replacement.

Thanks
