Its unheard of for a cable to break in a loom unless it has a partial damage from manufacture and burns out at that point. This is less a case on signal cables. Did you bell out the cable whilst disconnected
Yes disconnected multi plug from ECU and connector to Stepper Motor. Then Ohm meter showed open circuit between pin 2 on ECU and if memory serves pin 19 on Stepper Motor. Put a pulse tester on offending wire and it looks like its parted by NS of front cross member where its clipped (theres no accident damage). Ive only run the wire temporarily as I was short of time but Im attacking it to run the wire
As promised I stripped the offending (Green) wire completely out of the loom. For God only knows what reason (maybe someone had really pulled hard on the loom sometime in its life) the wire was broken around about the Temperature sensor area on the Cyl Head where it starts to lie in the L shaped channel thats runs round to the Injector TPS and Idle Control Motor It was a clean break completely through
It sounds like it was damaged in the manufacturing process. These things are made on loom boards and ty-wraps are often added and then cut off during the build sequence.
well and know you can get some seriously good power from it but after consideration Im going to do minimal mods to it because I think in a seicento 120bhp is plenty So well see how it goes Thats how I sold her over 2 years ago and heres what she looks like now Looking sorry for herself but lots of tlc to come her way Watch this space gonna be some big changes over the year Jef __________________ fiat

oooo found this httpwww.fiatforum.comshowthread....ghtabarthkit search is also ur friend xxx
There is an ICV which could be dirty. Too tight a throttle cable and vacuum leaks are also cause for hunting. Cheers SPD

I think Im mainly cut up cos I loved that car sooooo much but also I think it springs from a lack of independance - and although Im working again 20hrs a week isnt really enough to fund a motor when youve gotta worry about where the rent moneys coming from sigh... ...got some job interviews coming up soon though so fingers crossed Ill be able to at least pick up a cheap cinquecento or early mk1 seicento
Hi ive been hunting high and low for a seicento sporting fuel tank where did you get yours from
The block temp sensor has no bearing on the ECU it reads the one in the inlet manifold . Throttle cable too tight can cause it to hunt as can incorrect adjustment of the throttle stop. Have you got the vacuum pipes on the back of the TB the right way round Cheers D
Sorry I presumed the car was fully serviced if not thats the best place to start. Cheers D
Hi guys I have changed the fuel filter to a genuine unit and the hunting has now been only occurring during the first few seconds from the engine start while the auto-choke was on but after it went off the hunting stopped. Now (after a month or so) it has started occurring in between driving Does anybody know any other reason this is still happening If so please let me know cheers.
Its a 899cc if it makes much difference...
Could be temperature or air sensor

Thanks Arc. I tried disconnecting the TPS and it made no difference. Ive also had chance to get a ICV and TPS from the scrap yard but they both made no difference. Whilst travelling there and back the car cut out a few times on idle and was differcult to re-start - could this give any clues Could the fuel filter cause hunting I only ask as the fuel filter hasnt been changed since Ive had the car (naughty I know)...
When hunting for air leaks on the inlet side a light spray of WD40 or similar or possibly easy start fluid onto suspected areas will cause a change in engine speed if it gets sucked in. Dont spray too much at a time. a) it gets messy. b) too much can cool the inlet manifold briefly also causing a change in engine speed. c) too much may upset fuelling and catalyst. If you suspect air leaks out rather than in washing up liquid will bubble nicely.
Its still there - httpwww.fiatforum.comclassifieds...t12264&cat55
if your fuel guage is horrizontal and on the right (clock on left) its a electronic speedo. if your fuel guage is vertical and on the left (clock on the right) its cable. happy hunting -) 1999 was also the switch over year so yours WILL be a electronic speedo give it a tap and if that doesnt fix it try a new pulse sensor on the box.

Going off the thread topic a bit but it seems finished and you lot can surely give me some answers and ideas. Heres hoping your all subscribed As Im sure you know I have put the 1.2 16v engine into the Sei. I have the Super Sprint Punto 1.21.4 16v manifold which has a flange at its base. I need an exhaust system fitted for here on right to te end of the car. The standard bore of the Sei sporting is
Just be glad you only checked the bulb before hunting for a non-existant problem
Also - the fact that the air temp tracks the water temp exactly as it warms up and then sets solid is indicative of the fact that the air temp sensor isnt doing anything useful. The injector cant be short circuit all the time or it wouldnt run at all but if its intermittent it would account for hunting revs. Doubly suspicious of that wiring loom. Neil
Yeah I have the same car and mine revs up and down on its own also known as hunting not sure why it does it.

Thottle cable too tight is one cause. Make sure there is plenty slack at idle. You cannot fit a complete 1108 exhaust the manifolds come from different sides of the head but post cat you can use it although it will need an insert. The 1108 pipe is larger bore than the 899. Cheers D
