M35 Ecu Read

[ddrallystagea]

Hi all

My M35 has developed a miss again, and as it only does it when it's warm, I'm thinking that it may by a coil pack again.

Can anyone here in Sydney (north preferably) plug it in and possibly tell me which one? (if that is the problem...)

Is it the Consult II for M35s? My local guy suggested finding a stagea specialist to save time (and money).

Thanks in advance

Kind regards

Andrew

Mine is now doing the same. Issue is if once you plug it in and there is no miss then ypu wont see it on the scan.

Consult II works on my stagea. Ive been told to catch it when its happening.

Error codes won't tell you what coil pack is dodgy if any. It can throw a general misfire code, but it won't narrow it down.

Does it have a check engine light illuminated?

Consult 3 can help though, it can disable coils and injectors to pinpoint the issue. Nothing you can't do from under the bonnet though.

Have you changed the plugs? LFR7aix

Make sure the coils are plugged in properly, sometimes they missfire if the plug isn't pushed right in.

Make sure the plugs are on the correct coils, this is easy to mix up on the VQ.

The VQ25det coils are very reliable, and the one faulty coil I saw (in 6 years) threw an ignition error code. More likely there is something else wrong. Check the condition of the plugs first, they usually tell the story.

Hi all. Thanks for the responses. I've had trouble with the coil packs in the past, and this feels like that. The plugs are only 12 months old and there is no check engine light on.

I was guessing coil pack because it felt like last time... It also happens when it warms up which led me to think that it's electrical. It's been running fine since I replaced the couple of coil packs but as they were aftermarket non-genuine it may be one of them (or both).

Will make sure they're pushed in and check the condition of the plugs (spark and the connectors) and see if this helps.
