Honda HRV loosing power when warm
Discussion
Hi all, I'm new to this forum. I am looking for some advice. I have recently bought a 2004 Honda HRV Vtec. When it is cold, it runs great, but as soon as it's warm, it is down on power. I haven't got any warning lights up. I can also smell something burning after I've taken it for a run. My thoughts are it could be an O2 sensor or the cat.
I only bought this as a winter run around and don't want to spend a fortune on it, by guessing and changing parts until it's fixed. Any ideas would be greatly appreciated.

Diagnostic guy turned up yesterday. He found no fault codes. What he did find was that the plugs were shot to bits. The gap was about 3mm and the electrodes were badly worn. I didn't even think about looking at these because it was ticking over fine and not misfiring. So we changed these and it's made quite a difference. He also found that the Lambda sensor waveform was a bit erratic. He's recommended that I run it for a few days with the new plugs because it's been running so rich to try and clear it out. If it's still not right after a few days I'll replace the Lambda sensor.
Pumaracing thanks for your wise words!!! I don't pretend to know much about cars hence why I posted on here, but if the engine had been poor starting and running rough then yes I would have checked the plugs and leads etc. the diagnostic guy spent around 45 mins of road tests etc and only checked the plugs as a last resort to check the colour. I suppose we can't all be perfect.
I am starting to struggle to get my head around this. I posted on this forum to get some advice on a problem that I have never experienced in 28 years of driving and loads of different cars. Apart from the initial advice, most of the replies seem to be criticising the methods used to rectify the fault. One person in particular is down right rude and should keep their opinions of other people to theirself.
Mikey did an excellent job in rectifying the problem. He was methodical in his diagnosis. His rates were very reasonable and I would have no hesitation in using him again. I would also recommend him to anyone.
