Valver misfire whilst turning left

Post by tomwyllys » Mon Jun 27, 2016 4:34 pm

Hi all

Quite a strange one this... When cornering to the left at medium or high speeds, for example going round a roundabout, the engine splutters and coughs, before immediately ceasing to misfire as you straighten up. It only occurs when you have your foot on the gas and have got a bit of a lean on. I haven't experienced the problem turning at slow speeds or during gently sweeping high speed turns. It doesn't happen at all whilst turning to the right.

Any thoughts would be greatly appreciated!

Low oil level/pressure.

Edit: Left round roundabouts? You're nnot in the UK then?

OIL pressure? :? :P

Sounds like a worn electrical connector to me. Something tugging at it which you turn in that direction. I'd go over all the connectors like the AFM and TPS and see what you can spot. Unlikely to be fuel related on an EFI car, unless you've got something blocking the pickup in the tank.

Cheers Kitch, will check that out.

And good point Jay, I should have said 'whilst exiting a roundabout'!

It's my understanding that one of the Valver ECU's shuts down on low level & pressure. I don't know which as I've never run mine low enough to find out.

Alternatively, it could just be the muffler bearings.

It doesn't. Ask me how I know :(

I have EXACTLY the same thing, albeit in a diesel 309 and when turning right rather than left... this is very little help to you, but know that I share your frustration in trying to work it out!
