miles2102 Posted February 1, 2015 Share Posted February 1, 2015 Very strange idle issue,it happened one morning and won't go away since then. Basically when I start the car and ifs idling as normal I hear a click somewhere under the dash near all the relays etc near bonnet release, as soon as it clicks the revs jump up but it's getting more frequent and very very annoying!! Any ideas anyone??? Quote Link to comment Share on other sites More sharing options...
miles2102 Posted February 1, 2015 Author Share Posted February 1, 2015 I think it makes the boost solenoid click as well but not 100% sure? Quote Link to comment Share on other sites More sharing options...

miles2102 Posted February 2, 2015 Author Share Posted February 2, 2015 Haha oops cheers bud still a bit new to it all Quote Link to comment Share on other sites More sharing options...
savage bulldogs Posted February 2, 2015 Share Posted February 2, 2015 Have you checked for vacuum leaks ? It should have a 3 port boost as standard, where do each of the 3 ports/vac lines go to ? Have you tried cleaning the boost solenoid with electrical contact cleaner , Quote Link to comment Share on other sites More sharing options...
miles2102 Posted February 2, 2015 Author Share Posted February 2, 2015 It's got 3 port and top hose goes to turbo housing, middle to wastegate and bottom to air intake. Then I have from the boost pressure sensor to a t piece with one hose to boost guage and other to top of inlet manifold is that correct? Yep cleaned it out and tried a spare too with still no joy.

miles2102 Posted February 9, 2015 Author Share Posted February 9, 2015 Pretty certain my issue is with the idle needle on my clocks not working correctly after all the farting about I've had to do. Seems ok at the moment after changing the clocks but only been on a 10 min drive so I guess time will tell Quote Link to comment Share on other sites More sharing options...
savage bulldogs Posted February 12, 2015 Share Posted February 12, 2015 I should use the "participated thread" tab more often ..... As I answered your vac line question on somebody else's thread [emoji39] 3 port set up seems right to me When you say pressure sensor do you mean map sensor , atmospheric sensor or pressure to digital converter for the gauge ?

miles2102 Posted February 12, 2015 Author Share Posted February 12, 2015 Well I've changed the clocks as the was a burnt out wire on the back but it's not really made any difference to the idling issue. Regarding the pressure sensor I meant the sensor that sits directly above the 3 port. It's weird as I've got the cel keep cropping its head up and also a click which sounds like it's inside the car under steering/dash area, it clicks generally under very low revs as in setting off etc but when It click it seems connected to my idle making it rise to about 2k. It's very bizarre Quote Link to comment Share on other sites More sharing options...
savage bulldogs Posted February 12, 2015 Share Posted February 12, 2015 Is there any fault codes stored as it does sound like it might be electrical Quote Link to comment Share on other sites More sharing options...
miles2102 Posted February 12, 2015 Author Share Posted February 12, 2015 Yes just the idle control code 24, it's driving me nuts I'm thinking of just having done and sending it in for repair now, I don't know which direction to look next with it haha Quote Link to comment Share on other sites More sharing options...
savage bulldogs Posted February 12, 2015 Share Posted February 12, 2015 Have you tried giving the icv a clean and checking the filter between the icv and inlet is clean and not split Quote Link to comment Share on other sites More sharing options...
miles2102 Posted February 12, 2015 Author Share Posted February 12, 2015 Yep tried that. I think it's definitely electrical as I've swapped the engine out for a known fully running engine and tried 2 different ecus so I'm presuming that would rule out a sensor issue? It's killing me not knowing the problem. Surely it has to be wiring?? Quote Link to comment Share on other sites More sharing options...
Ash007ks Posted February 12, 2015 Share Posted February 12, 2015 unplug the maf sensor and see if it runs better, if it does the maf is the issue. Quote Link to comment Share on other sites More sharing options...
miles2102 Posted February 12, 2015 Author Share Posted February 12, 2015 I've tried that too, should have mentioned It sorry, I've got one from mine and a spare 3 but seem to make no difference which ever one I put on Quote Link to comment Share on other sites More sharing options...
Ash007ks Posted February 12, 2015 Share Posted February 12, 2015 maybe clean the ICV with some brake cleaner as in the bad months these can get covered in crud. Quote Link to comment Share on other sites More sharing options...
miles2102 Posted February 12, 2015 Author Share Posted February 12, 2015 Yep good call il give that a go over the weekend It's killing me now I just want it running right if surely can't be doing it much good running crappy all the time!

Ash007ks Posted February 12, 2015 Share Posted February 12, 2015 other than that it could be numerous things, Blowing exhaust gaskets , to leaky vac pipe as stated, havent had the ICV on the scoob, but on my RS turbo its a bugger for crudding up.

savage bulldogs Posted February 12, 2015 Share Posted February 12, 2015 Maybe see if .... Throttle butterfly is returning properly, check the plug/wiring to the throttle position sensor (black box on the throttle body) , check grey engine loom plugs. let it idle and spray some electrical cleaner around the vac and boost pipes to see if the idle rises to locate a leak . If it's not any of those best bet would be a auto electrician preferably with a bit of experience with scoobs Quote Link to comment Share on other sites More sharing options...
miles2102 Posted February 12, 2015 Author Share Posted February 12, 2015 I agree with both of you I think I need a good weekend checking over bit by bit then if that fails then have to send it in Quote Link to comment Share on other sites More sharing options...
Ash007ks Posted February 12, 2015 Share Posted February 12, 2015 Carburetor spray is better for check the idle as it makes the revs drop if there is a leak where your spraying Quote Link to comment Share on other sites More sharing options...
miles2102 Posted March 1, 2015 Author Share Posted March 1, 2015 Right had a bit of a result this weekend, my idling issue is pretty much gone now. Turns out it was the coilpacks as I did the newage coil conversion this weekend and seems to be running A LOT better now, no stuttering or erratic idle. Running lots better BUT still feels a bit stagey on acceleration but that's another issue to solve but all in all its running quite good touch wood!
