So, not a million miles removed from my last post on this subject. Our Twingo is playing up again..
Our car is a Twingo Freeway. 1.2 8v, ’10 plate. It’s done about 19,000 miles.
From cold it’s stated misfiring, and over time this has got worse to the point that it barely runs on the first start, sometimes. The Spanner and Engine lights come on for some time after the misfire too. Vibration can be felt through the gearstick at that time.
Usually either a couple more starts, or a few minutes of driving, or idling with the foot gently on the gas will clear it. It also seems to be using more fuel than before the problem started.
It’s just come back from an MOT and has passed, even the emissions.
After a few minutes of driving, the car feels fine.
The garage tried changing the HT leads, but that wasn’t it. They also used some sort of datalogger to read the error logs, apparently it said: misfire on cyl2, and, later on cyl 4 – this confused them because the issue seems to have moved. Their suggestion is to take it to a Renault garage because they will have various spare parts to try, whereas this garage will be be ordering chargeable parts which may, or, may not fix the problem. At its last service it had one sparkplug changed, but I guess this is not the issue as the misfire moves. The garage that did the MOT said they’ve pulled the plugs and checked the gap etc. No problem found there…
So – any suggestions? I have a basic knowledge of cars, a multimeter and a few spanners/sockets. What can I test myself to help minimise the labour costs if we take it to dealer?
I’m thinking maybe a sensor issue somewhere? Temperature?
Can I tell if the coil is out of spec in some way?
Anyway – cheers in advance for the help, or even for just reading this far 🙂
Regards,
Sam
