FLYGTI Posted June 12, 2013 Report Posted June 12, 2013 Hi all. Having trouble working out what to look at/replace after throwing code 12, 14 and 24. I know what they relate to but not sure if I should just replace the parts or how to test. I don't like/trust anyone with my baby as most wouldnt know earhole from arsehole when it comes to the crunch and not wanting to pay $70/hr labour. Starts fine all weather, had some missing issues due to afore mentioned dodgy mech putting wrong plugs in (missing under load) new plugs fixed that. Only issue now is its hunting ever so slightly and becomes rough at idle once warm It will hunt until I come to complete stop then I notice small idle bounce only about 50rpm. Revs wont drop below 1100/1200rpm even with idle screw full closed and I'm still getting vacum from idle control module when hot. Check/bleed cooling system. I am seeing froth in radiator not oil though as comp test is firm across the board. any help or will be nice or tell me I'm being a nance Quote
Hiro Protagonist Posted June 14, 2013 Report Posted June 14, 2013 What is the idle like when cold? Quote
FLYGTI Posted June 14, 2013 Author Report Posted June 14, 2013 (edited) Its is still jumpy when cold but gets worse when hot like a bad vibration.. might be vibrating exhuast/cat. Codes 12,14,24... 12 RPM Signal No G or NE signal present for 2 seconds during cranking Open G circuit Open, short in G or NE circuit. Distributor ECU 13 RPM signal No NE signal for 50msec at 1000rpm. Same as Above 14 Ignition No IGF signal to ECU for 4 consecutive IGT signal during engine running Open/short in IGF/IGT signal from igniter to ECU Igniter malfunction ECU 21 O2 sensor Open/short in heater circuit of oxygen sensor for 0.5 seconds Amplitude of O2 sensor reduced to 0.35-0.70V continuously for more than 60 seconds O2 sensor vacuum sensor ECU 22 H2O temperature sensor no signal at THW water temperature sensor ECU 24 Intake Air Temp sensor no signal at THA Intake air temp sensor ECU Think it might be Ignition control module. Ive given up playing mechanic and will be handing it over to recomended guy. PLus needs new CVs from goat track roads ive been commuting on down nimbin way ;) It was out in the rain for a month during bad weather and think is just fragging out. The mighty beast has 354000km body wise newish rebuilt engine 60oooks ago.. still punches out redlines all day long (not that I do it all day long) Excedy HD clutch helps ;) Edited June 14, 2013 by FLYGTI Quote
