172 Phase II
As the title says, I have a nasty lumpy idle on my 172 phase 2. It started doing this after the cambelt and dephaser were changed :S (The mechanic who did it also said it wasn't done properly the last time, with tipex markings and such..)
However, there's no problem at all in the higher rpm's. It drives and pulls fine then. Just until about 2.5k rpm it's bogging sometimes and stalls now and then when at standstill. (So I'm heel-toeing towards stoplights now :clown
I changed the plugs with new ones. I also ordered a set of leads. If it's not that I'm going for the coilpack.
Anyway my question is: can I do anything to try to pinpoint the problem? Like unplugging the leads or injectors one by one? Or the lambda? Maybe other sensors to check?
