injectors

[kingwick]

my ph2 172 is running rough think it might be injectors. took the plugs off and all for plugs are getting power. then with car running removed plugs 1 by 1 no1 almost stalled no2 made no difference no3 almost stalled no4 made no difference swaped no 1 and 2 injectors around and tried again but everything stayed in the exact same order. !!!
any one else experienced this ? if it was straight forword i would just replace the injectors

if you changed the injectors but the problem didnt move cylinder then it's not your injectors... get a code reader on it... could be something you're not looking at, like your lambda sensor causing it to run rough

swap the two around, one of them is only used for diagnostics...

does the car feel rough bellow 4k rpm only?
