Hi everyone, I am new on this site to see if someone can help, hopefully this works.
My 1998 legacy 250T EJ25 wagon has, what I would call a flat spot, or lag even though it's not turbo. It is happening at low revs when I accelerate from lights ect, or just when I want that extra little bit of speed, it does eventually get up and go but just seem to take a while to sort it self out. I took it for a good blow out on the open road and went very well.
The CEL is not coming on. I have replaced the knock sensor, Co2 sensor, spark plugs and leads. Other than this frustrating flat spot, it is going well and idles fine.
Does anyone know of this problem which can point me in the right direction, or should I carry on changing maintenance parts next would be fuel filter??
Or could it be something like TPS, ECU mapping ect...... Which I would have to take to a specialist.
I appreciate any help.
Thanks
Pete.
