    Hi,

    Basicaly my gti has been running fine, and today took it to get some oil for the clio, got home turned it off, went to go to the shop in it, and it sounds like its running on 3 or is in limp mode!?

    engine is very shakey and stalls if not revved..

    Checked all plugs and they all fine pretty light brown tbh tho..

    done compression test and all in the green!

    Completely stumped!

    Yeah for some reason, one off my injectors is fooked..

    i brought some redex injector cleaner and put it straight in the throttle cody and some in the petrol tank, and keep the car running for a bit then switched it off and left it for about 2 hours and it seems to be fine now, but think im gunna get some new injectors now just to make sure!

    Well last nite the problem was okay, i emptyd a bottle off injector cleaner into my tank then thort ill go get some petrol.. started the car sounded okay for about a min then started to sound like a motorbik again , drove to the cloest petrol station put some petrol in and it was the same! was very hard to rev and was very sluggish, but really struggling to rev, but felt like it wanted to! then the ecu light came on, made no difference to the engine but just came on

    woke up this morning and the car wouldnt start AGAIN! so took plugs out checked them, put a little bit off petrol in the bores and put it back together and boom car started.. but still sounds like a morotbike :| almost like its running on 3 again :| and the ecu light is still on

    Made a quick video, qautly is just so bad but its the sound really..

    The engine is shakey quite a lot and sounds almost like its running on 3!

    video sucks tbh, but the car isnt very free revving..

    could this be because i put to much injector cleaner in :|?



    Also it idels okay.. :|

    PLEASEEEE HELPPP!

    engine vibrates quite a lot

    think it may be injector again :|

    Could to much injector cleaner cause this?

    You want to be looking for a black sooty plug where the injector has failed to fire. Also unclip coil pack and turn engine over a few times to get some fuel into the cylinders. Remove plugs and see which ones are wet with fuel

    That's the only way to reset it limp mode just stops you accelerating over 3k

    This sounds a lot like my saxo issue, We bought a saxo that cuts out at low revs? And if you rev it then let it go down into low revs again the car shakes/vibrates for a few seconds... Any help?

    Thanks im new

    Seriously matey try the new coil pack separate to the new injector and see if it works so you can narrow the problem right down and find the solution. Seriously if the coil pack is faulty then one of the spark splugs won't fire and it will probably be wet from the in burnt fuel but sometimes it tends to pick back up just give it a try.

    Well my brand new coil pack is going to be here monday

    Also i have 2 second hand coil packs and they are both having the same problem.. so personly dont think it is the coilpack..

    But having a problem trying to source orange band ones, so trying to find out weather green band ones fit.

    This is my orange one:

    Run the engine from Cold and feel which exhaust isnt getting hot at least then u know which cylinder has the problem, I had this exact same problem a few days ago but mine was because the one of the injector rail plugs had fallen off due to the clip being missing...

    If the plugs spark while earthing them to the rocker cover then the coil pack is working !

    Well today fitted my new injectors lol..

    NO JOY.. so thort i would bite the bullet and took it to peugeot..

    Got there and one off my old college mates walks out off the garage in overalls.. and tell him the problem.. he walks back into the garage gets a couple off tools.. whips my inlet off.. (top part) and takes the plugs off my injectors and tests them and 1 and 4 arnt getting a pulse ATAL! he then shows me with some bulb thing that plugs into the connectors and 2and3 are bright lights and 1 and 4 no light atal..

    he turns around and goes wait there, runs back into the garage runs out with another ecu, and said they this one, its locked so wont start but you should get a light for a second when first turning it over.. so this will see weather its the wirers or not..

    he puts the ecu on turns the key and both 1 and 4 light up for a quick second..

    so my ecu is fu*ked again!! so now i have 2 ecus which have problems..

    so get home get on ebay and see some dude splitting a saxo vtr with gti engine in it, just down the road so went and spoken to him and got the ecu off him..

    He then give me a bit off paper saying it was remapped around 2 months ago it ran out off mot.. so throt bargain!

    so im praying that is my problem so going back to peugeot tomorrow for my mate to try that!
