Fluctuating / bad idle

[David]

Andy - the timing chain tensioners are NLA but I have several of both sides (LGJ000090 & LGJ000100) in stock if you need them £40 for the pair posted, just let me know

Aren't those guides, Colin? Looks like there are two fixed guides, two pivoting guides and two tensioners. Example here:

... (example only; that particular one is for a Mustang 2V up to 2000; later ones have a different lower crankshaft sprocket, I believe. Take care!)

Lots of good timing-chain "how-to" videos on Youtube and this Ford instruction sheet: https://performanceparts.ford.com/do...4-462V.DOC.PDF
