Suspect my EGR valve plus ? was played around with at last service. Went in running smooth as silk came out running rough and noisier injectors. Car from cold start and warm up fine but noisy injectors, take it for a run still goes OK, back to idle, rough and noisy

After a couple hundred or so ks idles smooth! Indicative of CPU taking time to correct and adjust to change. if that brought up a error code ,
it could have been deleted. :? Furthermore gauge which shows fuel usage per 100k went berserk and corrected itself at the same time.

So Question? what sort of meter do I need to connect to myOBD2 to check and if needs be corrected.


OR someone around the Greensborough area of Melb0urne that can help.

The EGR stuck open shouldn't make the injectors noisy, or at least it didn't for me. When the car started at idle it actually sounded really cool, sort of a cross between an oldschool big block V8 and a rotary. I had a different exhaust then though. The engine basically took no load, it would stall. Maybe they faffed around and shorted the electronics or something? A reset will mean the car has to readjust, but I'm sure it wouldn't be like you experienced.
I might add a pic of my car once I style the exterior a bit :).

The young mechanics were relying on the fault codes, which basically all got triggered. It was right before Christmas, so after pestering them the head guy he said he'll look at it and it was fixed later that day. Then relaying the story on here it appeared that nobody was aware they had them either. It's possible that on some cars they are stuck shut, which you wouldn't be aware. There are variations of the engine. New Zealand according to their website have variable lift, which we don't have. I believe it gives a flatter torque curve and better emissions. Would be interesting whether they have EGR valves. It also means the must have a different cylinder head?

what is your VIN number burfadel? it would be interesting to look at it on partsouq and see if there is a part listing for it in the EPC for the EGR.


Well all the lancers I saw and got regos for were 2.0 GSR, SX, ES, or Galant Fortis (sports back lancer, import I'd say)

and looking at the 4B1 engines they are all MIVEC unless I misinterpreted variable lift?

I know mine has! :(


Looking at the EPC for my MY08 I have a solenoid that it describes as being for the EGR system, but the hose(s) that come off it go to the Evap canister and the brake booster. there is no part number for the EGR valve in the schematic, or anywhere in the EPC, did I luck out?

Red Dots are the solenoid and coresponding part number.

12400 looks like a EGR valve. :?

Yes it is, but no blue circle means it isn't fitted to the car :wink:

does anyone know which of the CJ's haven't got an EGR system?

Also From when did the 2ltr engine start getting the clamshell exhaust manifold.
If you want to check yours,. the clamshell has only 3 bolts holding the heat shied, whereas the other has 4 bolts
Simple to check and report would be appreciated with year your car was made ieMY12 MY08 or whatever..
