DC5 Idle - Slight rough idle

[Kin]

Ive noticed recently my dc5 idles slightly roughly. It is 100% stock and used to be totally smooth and unnoticeable. Now I can feel it a little..

my friends say it is normal.. cars do that and it can be adjusted.. in the rx7 theres the TPS, is there something similar?

or is there something wierd going on?

When you say rough, does the car's revs jump up and down constantly?

Iacv, valve clearences etc. Those are the things I'd do first. That said I don't know if valve clearence have much to do with rough running.

It doesnt hunt, i watch the needle on revs and it barely moves, but i can feel the roughness sitting there.

engine mounts

Some things that will help fix idle problems are:
- Clean the Idle Air Control Valve (IACV)
- Clean the throttle body
If those two don't work or help, there could be a chance your tps sensor is faulty or a clogged fuel filter. Changing spark plugs can help too!

Goodluck!

i agree with Karl, if your rev counter doesn't move, chances are one of your (if not all) engine mounts are gone. thats how my car felt when my engine mounts were broken..

ahh yes, engine mounts. that would make sense!!
