Fluctuating / bad idle

[ColinE]

Hello all. I think we have found the Problem. My mechanic did a pressure test at the inlet and outlet valve. Everything was fine. Then he looked at the timingchains. One timing chain is loose. The other is tight. it looks like she's skipped a tooth.
Now i order new complete timing Set.

Andy - the timing chain guides 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
