    I have a saxo furio 1.4 2001. My problem is when I put my foot down the car starts to hesitate and slows down whilst juddering. A bit like running out of fuel. It won't go over 3k revs. I have been told it is either the coil pack or the cat. So I have changed both of these and spark plugs but still have the problem. Sometimes it's ok and back to normal, and then it does this again. Anyone got any ideas

    If the fuel filter doesn't work then it could be the pump. I usually let my car run low, ive been told it is bad as it picks up all the rubbish in the tank and blocks the filter

    You can cable tie the fuel filter into place.

    What does it run and drive like in general? You've just mentioned it doesn't rev above 3k, and you've just had the head gasket done. Has it been like this since?

    Could the timing be out?

    you people are all focused on the fuel while it could be the air filter. Could be caused by moisture, could be caused by excessive heat soaking, could be the filter itself being completely shagged. Service your car fully instead of guessing around. Almost there though if you already done the plugs and coil pack + fuel filter.

    It judders and slows down when I put my foot down and up to 3k. I did mention that. Yeah it has been since the head gasket but if the timing is out it will smash the valves and then the car won't run. The car does it and then it's fine so can't be that. I've just ordered a new air filter so that is hopefully the problem. If the fuel pump was knackered the car would be like it all the time.

    So far so good, air filter seems to have sorted the problem but depends how long this lasts lol

    Just found my coolant is disappearing and there is no pipe leaks, the head was on the skim marks so couldnt be reskimmed. Is this the problem, is it new head time

    Ok I've tried new fuel filter and air filter. Hasn't solved it. I had to replace the head as it was letting coolant in and couldn't be skimmed. This hasn't solved it. Apart from the fuel pump has anyone got any other ideas

    Lambda or map sensor, could even be TDC sensor.

    Update, the car feels like it has a flat spot and if I take my foot slightly off the pedal, the power comes back a bit

    did you change map sensor? sounds electrical or the timing is out timing can be slighley out and still run and to be honest an air filter aint gona cause you there problems was the head checked when it was off even thow its been skimmed to its max still should have been checked with a straight edge and have you had a diag done sometimes your ecu will pick up a fault when it occours but not throw the light on

    Yeah changed the map sensor, I had timing and head both checked and I still have the problem. The codes I got were p0420 which is obv to do with there being no cat but I also got p0105 and p0110 but not too sure whether these are the problem because I had no codes before I changed the head. It's a nightmare lol

    Had exhaust welded as there was a big hole in it still no difference. Got someone looking at it Thursday and Friday. If they can't find the fault then it looks like il have to start saving and then goodbye

    Just had car completely tested and everything on it is working fine. The mechanic said the only thing he thinks it can be is fuel starvation. Does anyone know where I go from here

    test to see if the map sensor is getting voltage! should be getting a 5v+, 0v and a raw signal when the car is running and under load, the volts should be fluctuating

    Sounds similar to what was wrong with mine. Ended up being a load of shit in the throttle body causing it to not fully close (sucking in air)
    As soon as i cleaned that out it worked perfectly again, worth a go

    Ok cheers and will try and get car pressure tested before I spend money on pump. There is nothing wrong with icv, I had that checked

    My car now Judders when I have extra weight in my car and feels like it is stalling when turning corners and accelerating. Does this sound like a lazy fuel pump

    I had a similar problem except mine was running bad after restarting it after going to the shop or summat. Self diagnosed it, turned out to be the coolant temperature sensor. Brought a new one off eBay, fitted it and my car is fine all for the cost of £12 and 5 mins with a spanner. The ecu was putting the choke o. When not needed due to it thinking the engine was cold. You need the green coolant temp sensor and not the blue one...at least I did for my '97 1 litre.
