i have a sapphire cosworth all of a sudden the car has started spluttering when driving at a costant speed it wont idle it conks out spluttering VERY strong smell of fuel when your driving it hard or even speeding up slowly its fine. could it be a sensor etc any ideas woyuld be great thanks
cheers al check it tomorrow when its light. the car was ok when a set out on ma run then got slightly worse and worse till it wouldnt idle and rus like a bag of wank
As per above did you check the MAP sensor pipe? If so as said it may even be the sensor itself, you can use the flash code system if your software supports it as this will show you if either are faulty.
the plugs were covered in petrol replaced the air sensor (brown) and it was covered in petrol 2. the lines are ok. its over fueling not being starved. checked the map sensor pipe its fine a changed the fuel reg as well
how would i find out if the injectors are staying on and how to cure it if its the wiring?. a dont know if the map sensor is working properly as a dont have another 1 to check it
As i say the flash code would tell you this, as to the injectors the easiest way would be to use a NOID light other than that is just determine whether they are pulsing or no as if one of them has shorted to ground it will be permantly open.
update on the fueling problem got new map sensor fitted it,s starting ok but it splutters when you rev it let it warm up and it still splutters am thinking of putting new plugs in it incase there all clogged up wae shite any ideas
Thats probably the typical behavior as the software is programmed to act on the input from a 3 BAR MAP sensor which is different from the two, the blue sensor (CTS) is right at the rear left hand side of the head (Inlet) it's a little fiddly to get to.
when a bought the car 7months ago a replaced the blue cts. am trying to find out if a have the right 1 according to tms where a got it its a 3bar but diff colours if you check my other thred 3bar
