Morning all, I've got a problem with the copen where when I put my foot down to accelerate on a slip road the car will judder once (feels like i've hit the brake!) and the engine management light flashes up briefly. It then returns to normal and I can't get it to misbehave again. I only have a short ride to work so its only this last point where I get above 30mph up to 50 maybe 60. Has anyone had any similar problems? I had a full service last year and ive only done 3508 miles since. Oil is fine, same for coolant. I'm driving a 659cc 2005. Cheers, Lauren
You should be able to pull the stored trouble codes from the ECU. If you get a cheapo ELM327 OBD-II adaptor, you can do this easily enough. There are two options for an OBD-II adaptor, software or hardware. Software requires a "head unit", like a laptop or mobile phone, whereas the hardware solution includes buttons and a tiny screen to tell you the codes. I have a feeling it may be a temp misfire on one of the cylinders.
are you at wot giving it full beans as sounds like number6 said ether miss fire ona cylinder or your hitting fuel cut
Just had same problem, coil packs and new ngk iridium spark plug sorted it and running fine now, but be warned the coil pack are not easy to find so id try new plugs first. Good luck
