Check Engine Light
So ive had this issue for the past few days, in the morning, car starts and drives fine, as im going down the road after a few minutes the car accelerates, then the boost stutters then shoots off, for a say 5 minutes after the check engine light will come on and off, then eventually it stays on, a few times i have parked up and returned to the car 30 mins later and the light is off and the car drives fine till the next morning then it repeats, i do feel like the fuel economy isnt at what it should be, could this be a failing MAF.
the car is a classic MY00
on an ecutek tek1 map (done before i bought the car)
standard air box with a pipercross foam filter
if you need any more spec please ask

so i had to defrost the car this morning, so before i set off the car was up to temp, it drove normal will maybe a tad bit of hesitation,but i didn't get the CEL, is it worth just changing the knock sensor regardless.

the condition of the plastic i would say it is possibly the original from the factory, im going to reset the ecu as you suggest, make sure there are no codes stored, give it a go, but i think i will change it out anyway, thanks again for your help

as said just replace the knock sensor. it has a small cracks (usually not even visible to the eye) in the casing. Damp gets in overnight and then it throws the CEL next morning (or when it gets wet/rained on) once dried out with engine heat CEL will go off on next start etc - becomes more prevalent coming into winter months
rinse/repeat until such times as you replace the sensor
when you refit the new one, place a small washer on top same width as the collar so that when torqued the bolt doesnt press down on the casing

yer, the intercooler is my issue, i had to sort the pipe work out for it the other day as it wasn't installed brilliant, and i wanted to remove it, to get a better look at things, but i cant see for the life of me how they got it in there, it is an STI TMIC of a hawkeye i beleive so its long, the top frame of the intercooler keeps catching on the bodywork, ill have a fiddle this weekend to remove it, and do a bit of tidying up, cable ties in hand
