It definitely sound like it's the coil connector you've wiggled a few times - I 
guess that's the LT, rather than one of the HT leads. Unfortunately 
intermittent problems are the worst. I recall we had an engine on dyno once 
which had misfire probs, we changed all the parts one at a time and it resolved 
it....... We then changed them all back to the originals and it was still 
ok!!!! very frustrating. Anyway, back to your issue, has there been any change 
when the weather is damp? eg first thing in morning compared with afternoon? 
I've known people ( done it myself) fit 'super duper silicone replacement 
leads' which are ok if it's dry, but track terribly when damp - clue is the 
boots which slide on the ends, rather than being fixed - the damp gets between 
wire sheeth and boot - like Blackpool Illuminations in the dark. The rev's 
rising and falling sounds like something else though  (Maybe Idle speed control 
valve?)- Jim may be along in a while, and will probably know straight away.

  Subject: [Quantum Owners] Help! flummoxed on cvh issue


  Hi All
  Any thoughts, suggestions or help on the following issue with a 1.6i mk3 XR2i 
engine in my son's H4. I'll go through the issues as they've come up.

  The car would occasionally die, and my son had also reported that it 
kangaroo'ed - the rev's "randomly rising and falling (seemed to happen if the 
car was hot, as it was always OK when I got to it in my role as IR)

  On any occasion it was dead, I found there was no spark, and simply wiggling 
the connector on the solid state coil pack would seem to bring it to life.

  I took the plug and a length of cable off the car and inspected and cleaned 
the plug - which all seemed ok - when the problem persisted I bought a new coil 
pack. when I swopped this, I had a problem with the car, it ran OK in neutral, 
but when trying to get off the drive, up hill, it sputtered,back fired and 
died. I swopped the coil packs back, and checked they were exactly the same, 
which they were. I became convinced having had the plug leads on and off the 
coil pack a number of times, that I'd messed the firing order up. I traced the 
leads and labelled them, put them back with the new coil pack and all was 
seemingly OK ( the car has previously had new plugs and plug leads as part of a 
"service")

  The problems with car dying and reported kangarooing continued. I've checked 
all the breather pipes as suggested by Haynes, and also changed the fuel 
filter, as it was suggested to possibly be a fuel problem (despite the strange 
wiggle the connector fix for no spark) one other slightly strange thing 
occurred during the issues, the rev counter packed up. I had a look at the 
wiring diagram and couldn't figure it out, clearly wasn't a feed from the 
distributor!!

  I used the car for a couple of journeys, and experienced the Australian 
phenomena. It initially seemed as if the car was in the wrong gear, and 
slipping the clutch and upping the revs got through it, but later I had the 
full kangarooing and random revs, followed by the engine dying. A quick check 
under the bonnet when it wouldn't restart and a wiggle of the coil connector 
and away we went.

  I was working away and didn't have the time to do any more work on the car 
until recently. I checked everything over (connectors etc) and tried to get a 
replacement coli lead with wires attached, but my local ford breakers have shut 
down, and my inquiries have so far proved fruitless. 

  I tried the car out late last week, having finished working away - it 
wouldn't start, but the jiggle trick sorted it. I now noticed the rev counter 
was working again, but seemed to be showing incorrect readings (c 3000 revs for 
a fast tick over). The car seemed OK, but trying to get it off the drive 
revealed the sputter,back fire and die, problem had returned. I convinced 
myself that the nature of the issues, suggested that the ECU must be at fault. 
Haynes suggests that if any of the various sensors have issues the engine is 
likely to run but not at optimum, so I found one on E bay and bought it. It 
arrived today, and chnaged it out - and I've got exactly the same problems with 
the car - rev counter works but reads high, and the engine fails under load.

  oh for the days or carburetors and points
