Misfire

[Jon_vr6 1]

Got in the car this morning and noticed it felt and sounded different than usual. Proceeded to open bonnet and noticed arching on one of the spark leads where it joins to the coilpack. What's the first port of call the coilpack isn't that old Bosch one. I'll try and post video in a minute.

Cheers

Beru was the other "good" make but I've got a Bremi on mine.

 

You could take it off and check for cracks and glue it as a temp. fix

[Jon_vr6 1]

Usually when the coilpack fails though it fails in pairs. So would go down to 4 cylinder mine seems to indicate 1 which means lead or spark plug?

Ahh sorry I was in a webex at work so mis-read. Doesn't sound like the coilpack then but might be worth inspecting. If you're after leads I bought a set from https://mrretroleads.co.uk/ circa £50 & hand made by him.

Actually another idea - you could swap the lead to another cylinder and see if it responds the same or if you have a multimeter check the resistance of the lead (set to Ohms). Prob best to whip a few of the leads off to compare resistance readings.

Yeah the leads I have on are from Mr retro leads (my car engine on his ebay ad). Now I've found my spare coilpack (ecp crap make but will do for testing purposes) and I've got spare it leads as well I can test tomorrow.

[_Matt_ 32]

ahh small world - I have them on mine too! Good luck with the testing..!

As said Jon , swap the leads first.

Changed coilpack for spare known good one and all back and running on 6 again rather than intermittently running on 5. Sprayed a mist of water over the leads at the coilpack and no nasty arcing and after a good run out it's back to its best. Going to replace the spare with a better make though so will get a bremi from euro car parts.

 

Only one small crack on the coilpack in the middle shame as only been on 4 years.

I have a Bremi on mine. I was looking for a Beru as supposedly better but no problems with mine. I've also bought one of those plates that sit between the coil pack and the engine to limit the temperatures to avoid the cracking. There is a guy on the facebook group making them for around £25, comes with longer bolts too - Matthew Huggins is the fella to contact.

Glad you got it sorted Jon .

Sexybourbon on here also supplies the coilpack spacers

I bought one too - for £25 it’s got to be worth it.

Same guy Hasan - as I say, worth it for only £25 - coil pack might last longer than normal.

I had a spacer on the one that failed so didn't seem to help been on 4 years.
