Hi Guys,

I'm hoping the technical geniuses here may be able to help! I have a 1.8 ZVH EFi in my Fiesta RS Turbo, it runs and Idles right, but is running really rich, about 8-10% CO! it was on beige injectors and an MSD Chip, but we removed the chip and replaced the Blue injectors, I have checked all the sensors and they seem to be OK, I have replaced the CO pot as it wasn't making a blind bit off diference, it help a little! I have taken the head of as i wanted to lap the valves in, as we forgot when we built it, and also I'm replacing the cam and followers as they are worn, I dont think that this will cause the issue, but maybe contribute!?

I'm considering getting the car up and running again, and running it for a week or so, see if it clears up and settles down, as the engine was a fully rebuilt block, but then I dont want to run the risk of bore wash!

I would love to run custom mangement but I cant really afford that right now!

Any advice or pointers would be a great help and really appreciated!

anyone interested in seeing the car..
