Question about 2003 Mitsubishi Lancer

Loss of power Mitsubishi carisma 1.9 DiD 2002

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?
Mike.

    Have done this, didn't help.

    Sorry, Ourhowse, but I'm new to this and did not mean to offend, I guess I clicked the wrong thing by accident, in my attempt to reply to you, what I really mean is that when the car was in the garage being checked, they replaced the fuel filter, and it is still the same!The problem first started months ago, when I noticed that the engine warning light was coming on intermittently, about every couple of months or so, at the time,the car; and when I say misfiring; was accelarating like it had a flat spot every so often if you know what I mean? but then would be ok most of the time; well last week I was coming home late, doing about 60 mph, when the light came on, and the engine cut out. It would not start and I had to be towed home. So as I said earlier, I had it towed to the garage, they put their reader on it,- and said they couldn't find any fault? they pumped the fuel priming pump, changed the filter, managed to reset the light, and I got my car back.

    This was last week, and just tonight it has started again, although it has not failed to start, it is severely lacking in power so much that it almost stalls in first gear, and has a reek of black smoke coming from the exhaust! hope I've explained it properly? Help?

    Thanks. Mike.

    P.S. re timing belt, this was changed at 70000 miles, car is currently at 96000 miles.

  • mboyle007 May 21, 2009

    Thanks Ourhowse, when you say changed plugs & wires, are you talking spark plugs? because it is a diesel engine, all that has been done is the fuel filter changed, the garage didn't show any fault when they hooked it up, and the ecu light was on at the time, but they managed to clear it.

    I'm now thinking of taking it to the dealer, it costs £60 for 1 hour of their labour, and it would mean using the proper diagnostic tool, & hopefully finding out the fault, then I can see where to go from there?

    Thanks. Mike.

    Thanks raylnmax, here's what I've done. Took the throttle body off, (giving access to the intake manifold), took the egr solenoid and mass airflow sensor off, I then stripped the throttle body, cleaned it with carb clean,sprayed the contacts inside the maf sensor, then there was lots of oily gunge inside the air intake which I tried to take off to clean properly, but could not get access to the nuts, so I sprayed what I could see inside the air intake, and cleaned off with a rag, I then put it all back together, and somehow it seems to be ok, the ecu light has even gone off? and the car seems to be running not to bad now. P.S. the black thing you squeezed is the fuel priming valve, which is what you have to do when you chanf=ge the fuel filter. Cheers.

    Providing it's not plugs or wires or coil, it must be the timing belt then. That's the only thing that makes sense. Either that or your exhaust is plugged, but that shouldn't make it misfire. It would just lack power.

    Oh, and PS ... thanks for the "inappropriate" rating. You already changed the filter, so i guess you get one too. Explain your problem clearly. We are not clairvoyant.

    okay. Well, first of all, thanks for changing that. So it smokes black, lacks power, and sometimes won't start. I assume you have changed plugs and wires by now. I am thinking now maybe Mass air flow sensor, faulty coil or idle control valve. But those things should have been found at the shop when they had it hooked up. Or maybe your buddy is right about the cam sensor. Do you have a good auto wrecker nearby that you could go get some of the above things from? I know they are ridiculous to buy them new. For sure get the cam sensor. Was the engine light on when they hooked their scanner on it?

    Omg! I didn't realize we were talking diesel! Yeah, i guess maybe they can figure it out. I was just thinking water in your fuel, but even that wouldn't make an engine light come on. Let me know what they find. This has been a puzzler.

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.

If the engine is hot. when you off it will not start again mitsubishi carisma


Vapor lock is a problem that mostly affects gasoline-fueled internal combustion engines.
It occurs when the liquid fuel changes state from liquid to gas while still in the fuel delivery system. This disrupts the operation of the fuel pump, causing loss of feed pressure to the carburetor or fuel injection system, resulting in transient loss of power or complete stalling. Restarting the engine from this state may be difficult.
The fuel can vaporize due to being heated by the engine, by the local climate or due to a lower boiling point at high altitude. In regions where higher volatility fuels are used during the winter to improve the starting of the engine, the use of "winter" fuels during the summer can cause vapor lock to occur more readily.

Mitsubishi challenger 04/05 wont start, has been


I would guess there is more than a single problem with your car. While sensors and worn spark plugs and other possible problems would cause bad starting and running, such things would rarely stop an engine. To stop an engine it mostly needs a fuel system failure, the loss of signal from cam/crank sensors or a failure of the supply to the computer or a failure of the computer itself, though immobiliser problems should not be ruled out.

It probably should be taken to the shop but please read the towing instructions in the vehicle handbook to avoid possible damage to the transmission.

Loss of Power from a Mitsubishi 1.9 DiD engine


Hi, check the air filter. Have helped friends in the past who have poor running vehicles that have been regularly serviced by a garage. I looked at them, found the air filter black with dirt....totally clogged up....never been changed since new!!! Many garages seem dont seem to bother changing it when they should!!! Cars need air to work (more air than fuel) so try this. Paul

Loss of electrical power


think this a problem for dealer mechanic with product knowledge,because all lights coming on then loss of power sounds like it could be an ECU fault being triggered by a sensor,or just a component in the ECU breaking down .It would need the computer connecting then running till fault shows up .sorry i couldnt give an instant fix

Mitsubishi Carisma 1997


its a very common fault with the GDi engine, normally first shows a fault after 60k miles. Fault will also make the engine feel slightly juddery on occasions whilst cruising... either/both Accelerator body or Cam sensor are the usual culprit. Both can be rather expensive.
