Re: 155 Problem

The indicators is most likely the relay.

The revs rising.....a bit more dickyfelt.....I've had that too on a 155. I think it was something to do with the idle valve or throttle body being dirty. Give them both a clean. The idle valve sits at the back of the engine and goes into the intake manifold IIRC....it's a while since I tinkered with a 155..........

Re: 155 Problem

Sounds like idle valve as mentioned. The indicator problem could be the relay but also the column stalks can get muck inside them which causes problems. They can be removed, opened up and cleaned.

Re: 155 Problem

Probably a bit late now but........

The throttle body can get a bit coated with oil, stopping the butterfly from seating properly in the tickover position.

You can clean it by spraying WD40 into the throttle body with the Flexi-pipe disconnected and the butterfly held open by hand. Then rubbing a rag or Kimwipe around until its clean.

Obviously with the engine switched off!
