Sent car to new mechanic. explained problem, missing and a vacuum leak i cannot find.
After test they said i had a coil issue, said i replaced coils twice in 2 months wasted another 1000 dollars on there recommendation, and the idiot proceeded to tell me, that I dont have a CAMSHAFT SYNCHRONIZER (or sensor) because i have pushrods. I wont tell you what i thought and said. took home noticed harmonic balancer had slipped, replaced, still same issue.Camshaft synronizer is about to be replaced.
Replaced parts list for a miss
3 sets coil packs
2 sets leads
2 sets plugs
1 computer
1 air flow sensor
2 O2 sensors
1 Harmonic Balancer
full set intake gaskets, valley, planem, throttle body etc
plus labour at 104.00 p/h ( the joys of a mining town price but not working at a mine)
and annoying the wife by having to use her (corolla). been 8 weeks now and looks like it will be ongoing until i can find someone who is capable of diagnosing. will let you know when its running as it should

Hey wolf ghost, my AU2 fairmont V8 had a similar problem. Turned out that a wire had worn through on the engine. I can have a look under the bonnet and find the wire I repaired if you like. Fixed it 100% after about two years of searching.
Mine would drive fine but on idle it would just drop revs like the ignition was cut then pickup again for no reason..
