ClubCJ - The CJ Lancer Club

It could be many things that cause a tapping noise.

As for warranty on the drive train is for only 100,000km for the original owner. You cant sell the car with the extended warranty.

The problem could be a few things. Regular issues are noisy injectors, airconditioner or idle pulley bearing. These things are very hard to identify and often only a trial of replacing one part at a time. A good mechanic or a Mitsubishi dealer will be able to find and fix the problem. Expect between $100-500 to fix the problem/s.

The first thing I would do is empty the fuel tank then put 10 litres of 98ron fuel and a bottle of injector cleaner in with it and go for a good drive around the hills making sure you open the throttle all the way as much as possible through all the rev range.

Yeah it is the carbon canister, i took mine to have a look at and they said its just due to the design of the carbon canister, just has a loud valve in it apparently.

You can get it replaced however i dont think they've changed the design yet

I have hear a nock noise in mine too and in other cj lancers that I have worked on too I can hear it in idle when itsdead quiet. It's more like a ,, put put,, sound do no what it is. Good luck

Mine is the same too, if it is the carbin canister, any info on costs to do this? My ES is on 5 yrs old now, so wouldn't hurt to put something new.

Noticed this with mine also, I remember my old CE was noisy at idle I'm the same way I get the impression it's a design common with mitsubishi engines
