VP has strange problem

[shanev]

Hey everyone,

My VP has developed a strange problem and it has me completely stumped. When it is completely cold and the key is turned to on the engine fan comes on straight away. Once I start it it idles roughly and the engine warning light comes on. The idle then smoothes out but if I rev it it runs like a dog. Also now when I turn the AC on the compressor does not kick in. Any ideas?

Cheers, Shane

ecu/memcal issue most likely, try another one and see how that goes

sounds like limp mode. tried an error code check?

I had some of those symptoms when my ECU died. I would be grabbing another ECU.

Turns out one of the spark plugs had the ceramic shattered (still dont know how this happened). Replaced it and reset the ECU and all good now. Thought it was strange the AC wasnt working but seems fine now.

Thanks for your input everyone
