bach 172

i have a 172 phase 1 and it has a slite miss on idle and has high hydro carbonsdose any 1 know wot this could be
 
Sounds similar to the problem i had recently, brought a coil and that wasnt the problem. So i took the top of the inlet manifold off to find out that whoever had worked on the car before i got it, they'd got one of the ignition leads crushed in between the top of the engine and the inlet manifold. It ran fine for 6 months like it also, then just one day gave in... Its a bit of pain to take apart, but another thing to check before you spend any money!

ive had it code read and it only comes up with a knock sensor.the computer sed it had no miss fire but quite clearly it has by listernin 2 it do u think that could solve the problum.i was also told to try swap the lamba sensors over and change the tdc sensor has any body done this and did it help.
 
I had the same with my ph2 172 and i took the ignition leeds off and gave the conections a good clean with sum wd40 and its ran spot on ever since
