car appears to drive fine all the time BUT sometimes usually after full throttle or sometimes even half i get problems. if ive just booted the car and then have to stop at a roundabout or a junction the revs are building and droping. from 1.5k to 1k as if im taping the throttle gently every half second. its anoying. sometimes gives a check engine light and sometimes not. ecu code shows idle control valve but ive cleaned all the coke off it with brake cleaner.

im stuck and i dont know how to sort it. can any one help?

stew

 

just read ecu codes and found

22 knock sensor

24 idle control solonoid

44 wastgate control solonoid

so i think i may just drive it off a cliff

ive dissconected the battery to restet them codes as i cant see the car running with all that going on. as for the wastegate ill clean the boost solonoid.

 

what fuel do you run it on?

could be the MAF sensor as that can cause knock if its faulty and plays tricks on your idle speed.
GAZ

 

the cars an import but i have a scoobyecu so i use optimax alone.
