right another problem with the olde escort.. the revs are rising and holding at 4k and when i dip the accelerator pedel it just rises and holds .. have checked the manifold for air leaks and changed ISCV .. no joy.. i no the maf is on its way but havnt got round to replacing it as is the throttle position sensor witch was unplugged(when plugged in the revs just fluctuated between 2-3k)... it was workin near enuff ok bar the slight loss of pour from the maf. i checked the fuses and number 15 was blown its a 10amp for the left hand dipped beam ..whenever i replace this and start the car up the revs start to go down but then the fuse blows and it goes bck up and holds?? any ideas folks??
