Project Daily Sigma (16V TU)

Ok I have an update to this situatuion...albeit rather confusing heh.


So last night we were playing with it, I had decided at work that I was going to try another coil pack...just INCASE the new coilpack was a dud...would be just my luck, as it happens my sisters old fiesta is still kicking about with the same coil.

So swapped it over, had to swap leads as well as they were different connection on the coil end...This meant that i had to "trim down" the ends of the leads to make them fit the 16v head..just the same as i had to trim down the ones from ATSpeed (under there instruction) to make them fit.... not the length at all, it literally just a bulge on the end, which has to be removed to make clearance.

Anyway, fitted it all, tried running it, and exactly the same, running like a pile of crap / misfiring etcetc...so was like, can t be that then...

Proceeded to puto them back on the fiesta, and now the fiesta wont start...other than the odd pop and fart on a few cylinders, but clearly totally screwed (running perfectly previously).. so then was like. wtf...has my ecu killed the coil or...

So was thinking about it, and decided the ONLY thing we had changed, was trimmed the leads....albeit still tonnes of silicon down over the plug, so couldnt possibly imagine how it could be causing an issue...

Found a set of OLD leads off a rover v8 i had lying around in the shop...so like these leads are twice to long and so old / perished its not even funny...but fitted them anyway, turned key and fiesta fired right up...so then fitted them to my car, fired up, and sure enough, missfire totally gone!! So turns out the issue all along, was the one thing i thought couldnt possible be an issue, the brand new leads..

Im still fairly confused,as cant possible see how triumming that bit of lead off the end could have caused it to i assume start arcing...either way im going to find some new leads with smaller ends on them and hopefully that will sort it... Drove it for half an hour, was largely fine, although did start to missfire a bit towards the end, but that could well be the useless leads i was using..

So there is hope...
