TurboTobz Posted October 28, 2012 Share Posted October 28, 2012 So I changed my thermostat today, I removed a section of the inter cooler piping to do this and of course the thermostat housing. Started it up took it for a drive it was fine, until i hit boost. It then got progressively worse, to the point it sounded like a scoob, was really hesitating 500rpm idle etc.I took the plugs out to check for water but they are showing no signs atall.I took the hard piping off the intercooler to see if any water had perhaps made it into this, but it seemed fine.It has magnecore leads which appear to be in great condition, but the king lead is a standard one and has a slight nick in it but it was like this before i brought it, and wasn't an isssue I have insulated it.Took the car for a test after all this and after a while it began to run better and idle began to become normal, it now seems boosting over the .5 ish area it's hesitating and sometimes even backfiring.Can anyone suggest what to do and try?

Broony Posted October 28, 2012 Share Posted October 28, 2012 Could be a few things, water in that king lead, dizzy cap if its defo not firing properly Quote Link to post Share on other sites
micky boy Posted October 28, 2012 Share Posted October 28, 2012 Did you take the King lead off when changeing the thermostat? to give you more roomIf so it might of already been breaking down but now you have moved it, its just finished it off! The King lead might be 9million years old and very brittle!!!If you know someone with a GT/Glanza round your way see if they will kindly lend you there lead then you can go from there Quote Link to post Share on other sites
TurboTobz Posted October 28, 2012 Author Share Posted October 28, 2012 yeah it's spluttering I was originally worried I overlooked the fact water may have made it's way inter the hard piping and done some damage but I'm pretty sure this is electrical. I really don't see how the water would have got into anywhere, although dizzy cap I could understand a little more. This car gives me nothing but problems if I work on it!

TurboTobz Posted October 28, 2012 Author Share Posted October 28, 2012 This areas pretty dead for decent cars unless you like the Nova/Corsa class lol. Hmmmmmm! Quote Link to post Share on other sites
micky boy Posted October 28, 2012 Share Posted October 28, 2012 Haha shame i've just given a spare King lead away Dose sound like the King lead is faulty though after all its the king lead so if its not fireing right then neither will the rest hence it idleing at 500rpm!.

TurboTobz Posted October 28, 2012 Author Share Posted October 28, 2012 yeah, it does seem the most likely culprit, it's idling better now, it's mainly over the boost it had problems i'm going to grab the king lead in tonight and dry it off with a hair dryer and then go to town with the insulation tape, then hopefully try it out in the morning once the bays had a chance to dry out. But i will have to track a new king lead for sure! Quote Link to post Share on other sites
Simon Posted October 28, 2012 Share Posted October 28, 2012 You will be getting a weak spark from that poor king lead at a guess this is why when it's off boost it's ok but then when on boost it will blowing the weak spark out causing the misfire. I would try calling magnecour direct they will probally sell you just a king lead if you ask nicely Quote Link to post Share on other sites

TurboTobz Posted October 29, 2012 Author Share Posted October 29, 2012 Left king lead on the computer and skybox over night and re insulated it, left the car to dry out over the day and now it's working and boosting like normal. Very happy thanks for the input much appreciated. Quote Link to post Share on other sites
