- VS series 3 5.0 ute
I need some help diagnosing an issue. I have a vt series 1, 304 V8 and up until a few days ago was idling smooth and running really well.
About an hour into a drive the engine light came on and I could feel a noticeable miss, lack of power and the tacho is not functioning properly.
The tacho seems to sit at same revs then shoot up to where the revs actually are.
Then engine light went off but symptoms remain. When pin 5 and 6 bridged it shows 12, all fine.
I put a timing light on and every cylinder has spark but number 2 cylinder seems to be intermittant.
I replaced coil, coil lead, number 2 spark plug, number 2 plug lead, ignition module. (I replaced these as I had the parts on hand)
Car ran a lot better (but still not 100%) for 10 min then back to rough idle and no power due to only 7 cylinders firing most of the time.
Any ideas would be appreciated before I tackle the head f##k of the distributor.
