Question about 2003 Mitsubishi Lancer
Engine management light on, starts ok but car very sluggish, prior to this it was at times as if the engine was misfiring, and then it would come ok again, now the light is on all the time and the car lacks power constantly, I took it into a local garage and they put it on their code reader, but could not find any fault showing, although a guy I work with swears it could be a faulty cam shaft position sensor. Please help?
I am no techno so bare with me.
I had something very similar. I removed the big plastic engine cover/shield.
At the rear of this just to the right off centre (back of engine compartment as you look at it is the throttle housing. This was split and massively reduces power and performance. I changed this my self for around £80 and the garage wanted stupid monies to supply and fit. It is secured by three bolts and again easily accessible. Once you have replaced this there is a a black pear shaped rubber thing that you squease and pushes the air out and fuel in (pressurises the fuel system or something like that). This is under the fuse box and is quite hard to see but once you have found it just squease it till it goes hard. Start engine and all should be well with plenty of power again. Hope this helps.

I read that it is the EGR clogged up and also the maf causing the problems. I was thinking of getting a carisma but good think I checked first.
Had similar(ish) problems with Carisma 2002 DiD.Car would start to reduce and power and light would come on. You could still drive the thing for miles and miles but only at about 30mph. Some times that problem would not show on a journey.Disconnecting the MAF would 'cure' the problem so I purchases a new MAF (about 130 Eure) in car excessory shop but it did not cure the problem when MAF changed. Still had intermittent problem and light coming on.Disconnected battery for ten minutes (to clear all faults for computer) and took car to garage when light came back on first time who said the fault showing up was exhaust gas recirculator valve (EGR Valve).Purchased new one in car excessory shop for 115 Euro and and replaced old one. Has a LARGE amount of bother removing the old valve. Had to make a tool for to go into the bolt holes of valve and also heat the pipe that holds the valve. The old valve was of the type that comes apart in two parts and they are (I would imagine) more difficult to take out that the valves that stay in one piece as you have nothing to hold (that why I made the tool, a picture of a tool is shown in the manuals).Light went out but still slugging in the low revs. Changed the MAF to the new one (I still had it in it' s box) and car back to normal.The two devices I purchased in the car excessory shop were for Renault F9Q engines and I believe they are the same as Mitsubishi.
