I have been working on my VR6 for months, pouring money in to it, and still haven't had a good ride out of her. Most recently I gave her a full service, new plugs, oils and filters (Including fuel filter), There was a problem where the power would come and go, I'd end up limping along with no power, then I looked and saw the cat was glowing orange. I replaced the cat and lambda sensor, and it happened again. Has anyone got any ideas what this could be? Or should I just take it to the scrapper.
