Will I damage anything?

[NYA]

Right, as you may know I've removed my damaged DC Sports exhaust manifold and put on the OEM and CAT for the upcoming MOT. My question is, will it do any damage running it like this for a short while? I have it mapped for the parts obviously, and it's on a Dastek chip(I know not the best). I'm planning on getting the manifold fixed and put back on, but I'm just a little concerned as to wether it will cause issues short term or long term.

Just remove the chip. Assuming it's on a harness.

You'll be fine Darren, it'll just run a bit rich. Nothing to worry about. It's going the other way that causes the problems.

If it was running mega rich (which it shouldn't do) over a prolonged period you'd get excessive coke build up and you'd start to get misfires as the plugs build up a layer of coke. Nothing major again, the majority of this goes away naturally when the air/fuel ratio is correct. You can "terraclean" it if it's bad, which doesn't require any stripping of cylinder heads or anything else for that matter. So all in all, you won't cause any lasting damage, it shouldn't even cause short term issues with the minor level of overfueling you're going to see.

Cheers H, put my mind at ease
