tortron Posted December 31, 2020 Share Posted December 31, 2020 as low as 3 months if its not got a good seal on it Quote Link to comment Share on other sites More sharing options...
Spencer Posted December 31, 2020 Share Posted December 31, 2020 I would chuck some injector cleaner through it also. One that has PEA in it that stuff actually works. Probably not the issue but if it’s been sitting with old fuel I have seen many a stuck injector from old fuel varnish /residue. what kind of idle control does it have? They can be pretty shit on these. I bought a manual 1ggze turd back in the day and as said above just had the idle wound up. Quote Link to comment Share on other sites More sharing options...
BlownCorona Posted December 31, 2020 Author Share Posted December 31, 2020 some slight progress/investigation today, but since i had a good block of time i mostly focused on colour sanding the orange peel out. but i noticed that the secondary exhaust manifold gasket was leaking, i forgot that during the manual swap we went to remove the exhuast from the headers back and one nut rounded off and and seized after a few turns before snapping off. the o2 sensor is directly in front of the leak. its a 1 wire sensor so not super flash but cant be helping. it needs fixing anyway so have ordered the gaskets and will do that first. for idle control these have a 6 wire ISCV. i dont know anything more than that. all i can really do is check its getting power. while i was out ordering the gaskets, i grabbed a can of throttle body cleaner, and will look to give everything involved a good scrub up. the idle speed when it wants to idle is just fine at around 900 - 1000. but its when its idleing down from a rev that it doesnt catch itself.

Spencer Posted December 31, 2020 Share Posted December 31, 2020 Try delete the ISCV and get it to idle on the throttle stop. Then you can go from there if you want it to work for cold start, idle up etc. Quote Link to comment Share on other sites More sharing options...
BlownCorona Posted December 31, 2020 Author Share Posted December 31, 2020 idle up reminding me of a symptom i forgot to mention. when it was idling by itself and i hit the ac fan on, it stalled out so it didnt seem like idle up wasnt working, not sure if this means somethings not operational or just part of the whole issue. id really like the car to function as if it were factory, but not at all against doing non factory things to get it there. can you get aftermarket IACV controllers that would have more adjustability?

Valiant Posted December 31, 2020 Share Posted December 31, 2020 It sounds like it the IAC might not be getting a signal from the ecu as it did previously. Can you find the manual bypass screw on the valve (if it has one) and adjust it from there? Quote Link to comment Share on other sites More sharing options...
BlownCorona Posted December 31, 2020 Author Share Posted December 31, 2020 i got bored home alone on new years and the bourbons just weren't filling the void inside me, so i went out and pulled the iacv off. i started to clean the rubber pintle valve with carb cleaner only to discover it wasn't rubber, and was actually half the size it started once id cleaned all the shit off. given it was nearly 12, i couldn't really run the engine long or rev it heaps, but a quick test felt positive. i probably should have waited till 12 and all the fireworks would have covered the noise lol. will see in the morning Quote Link to comment Share on other sites More sharing options...
BlownCorona Posted December 31, 2020 Author Share Posted December 31, 2020 Yuck (the throttle body is probably like this too) 2 Quote Link to comment Share on other sites More sharing options...
BlownCorona Posted December 31, 2020 Author Share Posted December 31, 2020 Again, I have been spending the day colour sanding while I have the rare opportunity of solid days to myself But the idle speed is significantly higher than it was ~2500 rpm after cleaning the iscv. So regardless if that was the problem, it was definitely its own issue. I'll get under the hood and wind the idle back down later today hopefully and see what happen 2 Quote Link to comment Share on other sites More sharing options...
BlownCorona Posted January 3, 2021 Author Share Posted January 3, 2021 Icv clean made it alot better, but still had issues. Got dad's timing light and checked it. Car was set at about 35btdc.. I bumped it a little advanced earlier but into a couple degrees. Anyway it's 99% good now shockingly. I suspect I could get it slightly better if I fitted something like an apexi safc II and fiddling with fuel down low. My brother has one in his lockup which I may fit at some point. They look pretty cool at any rate. The cars still mid polish job so havnt driven it, but am pretty keen to see how it's running on the street now. 1 Quote Link to comment Share on other sites More sharing options...
kyteler Posted January 3, 2021 Share Posted January 3, 2021 I guess it would probably pay to ensure you put some or run it on 100 or 98 when you get it back in use post paint sorting. Quote Link to comment Share on other sites More sharing options...
BlownCorona Posted January 3, 2021 Author Share Posted January 3, 2021 had been running on 95 pre paint job as 98 was not everywhere and real expensive. but recently npd have rolled out 100 at a reasonable price and nearly every station. 1 Quote Link to comment Share on other sites More sharing options...
Spencer Posted January 3, 2021 Share Posted January 3, 2021 Yup good outcome that cleaning the ISCV and setting the timing works. If its in the ballpark you should be able to fuck around and get it better over time. 100% on getting some new gas and a injector cleaner in there, I think the nulon one is the only over the counter that has PEA. 1 Quote Link to comment Share on other sites More sharing options...
