Bit of an update to this.....
Well firstly, this stupid thing is driving me so insane, I'm like a flys cock width away from dumping the petrol and putting an oem xud in it because its making me that mad!!
Im STILL suffering from no idea, and random midrange issues ill try to explain the full symptoms....which seem different although slightly linked...
So problem one, the ongoing idle problem.....So if you start the car with no idle, it just splutter etc and conk out, so you always start with throttle, will fire up, no problems at all, revs etc no issue...but let it come to idle, and it will just run right down straight away and cut out...however if you are very carefull with throttle and veryyyyyy slowly bring it down to idle (as in over 20 seconds slowly) it will idle, and once its idling, will happily sit there for 4-5 minutes...however after 4-5 minutes, it will start loping / spluttering, more and more, until it evntually conks out...to me sounds like its getting richer and richer until ICV runs out of range then it dies..also, if during the idling, you so much as breath on the throttle pedal, it will drop down and conk out.
The second problem is an intermittent problem (worth noting the idle problem is constant, its never idled ever correctly). So you can drive it all day, without a single issue other than lack of idle at times, but then other times you can be half way through your drive, and out of no where, the center 90% of pedal travel stops working, or at least, if your at cruise, it will just die off, loose all power (with pops / farts), so you start putting your foot further down...and no matter how far you go down, it wont start pulling again until your at 95-100% wide open throttle, then it will just suddenly spring back into action, and start accelerating (albeit down on power imo compared to normal)...sometimes this will happen constantly during your drive, sometimes just once, and sometimes never...
For example on a 2.5 hour drive at the weekend, it was broken the ENTIRE way up...had to drive constantly either WOT or slowing down....got there, parked up, left in the evening, first 2 miles just the same, then conked out at a junction (normal with no idle) fired back up, and drive PERFECTLY the entire way home, full power, not a single problem other than lack of idle, didnt touch anything.....
As you can imagine, this really is driving me insane, given im used to boosting dervs with 60psi, and i cant get a simple near enough stock engine to run correctly in the bloody car!
I have done the following, to of which NOTHING has made any difference to anything....
ECU - Replaced TWICE, so total of 3 ecus, all 3 do exactly the same, no change what so ever, all 3 are unlocked.
Injectors - Replaced for another set, no change, so put orignals back
ICV - Replaced for known good second hand, no change, so then replaced with brand new (NOT genuine, but thougth good enough to rule it out) again, NO change
TPS - Replaced for known good, no change (Do i need to buy a brand new one? Could this be at cause?
Map sensor - Replaced for brand new,no change
Temp sensor - Replaced for brand new, no change
Flywheel sensor - Replaced for 100% working one, no change
Engine wiring loom - Removed, re soldered every single connection I had to make, re taped and fitted, no change.
Lamba sensor - Tried 5 sensors, including the current one which is Nialls nearly brand new one....no change
Coilpack - Replaced with ford unit + HT leads.
The engine is just serviced / new plugs / new leads / new cambelt / waterpump / thermostat / clutch / newmans cams.
Ive pretty much replaced every single part of the system, and nothing seems to have effected anything...
Does anyone have any last ideas before I pull it back out and replace with something else, I really dont want to, I know im a derv head, but its nice to have something a bit different for a change, and its a great little engine to drive once it works...but im totally out of ideas and the ammount of money im spending on silly little sensors is adding up, and the entire point of a stupid little cheapy petrol is to stop me wasting money on the damn dervbus!!!
Cheers n gone!
