i have had f4r lump sat up for a while ,but now have it up and running but it hunting on tick over (up and down up and down)
i thought it was an air leak as the manifold have been off when the cambelt was done (not been running since) but after checking for air leaks a few times . i woundering if it could be water temp sensor ?or could the cam belt being a tooth out causeing the hunting?
thanks allan
Sounds like a breather fault split vac hose or probably a sticking throttle body.
Possibly idle control valve? remove try a clean or replace! but I must admit it does sound like a slight manifold air leak, can you hear a sucking sound anywhere?
How much is it hunting? them engines do
Regarding the belt being out, I believe it would miss right through the rev range if this was so.
Try spraying a can of carb cleaner around the engine and listening for an increase in tick over
could be throttle body, i will try that tomorrow.Quote:
