Valvebouncer 2,389 Posted October 5, 2017 I found this site useful when diagnosing minehttp://easyautodiagnostics.com/ford/4.9L-5.0L-5.8L/ignition-control-module-tests-3#2You may have to do the pip signal while it's running, keep an eye on it and see if it goes irregular as the misfire occurs 2 SPArKy_Dave and Outback Jack reacted to this Share this post Link to post Share on other sites

I wasn't sure if they used genuine Bosch components or not.https://www.ebay.com.au/i/222569602865 So Dave, they only use genuine Bosch components? If so I'll be buying one! You shouldn't pay more than $170 for a brand new OEM one outright. See if anyone has any - PAT use to keep stock I think, but not sure on their part number. However it says $320 outright - which is a bit outrageous IMO. If I really really needed one, I'd probably pay that though... Share this post Link to post Share on other sites

Only use NTK Oxy sensors on these things - NTK is what was fitted from factory. A dud O2 sensor shouldn't cause bad missing. Is it a rhythmic miss, or a random irregular fish-bite miss? I would head towards a hall effect sensor in the dizzy, and/or injectors which are clogged. Another thing that can cause random missing at idle, is a burnt out idle control circuit, in the ECU. 3 Slow250XC, Valvebouncer and Outback Jack reacted to this Share this post Link to post Share on other sites

Valvebouncer 2,389 Posted October 14, 2017 The slow to rev up could be retarded ignition timing, did you bridge out the two pins in the diagnostic plug and adjust it? Share this post Link to post Share on other sites
Demmo 295 Posted October 14, 2017 The slow to rev up could be retarded ignition timing, did you bridge out the two pins in the diagnostic plug and adjust it?No we just set tdc to marks on bottom pulley. And the rotor pointing to notch at no.1. How do I find out which pins as on my old xf. there was a plug under bonnet. Nothing on xg or my xh.. looks like I gonna have to Google it ThanksSent from my HUAWEI LYO-L02 using Tapatalk Share this post Link to post Share on other sites

Think I better go have a beer or 3 and play with Google an not the redhead Cheers demmoSent from my HUAWEI LYO-L02 using Tapatalk Share this post Link to post Share on other sites
SPArKy_Dave 8,831 Posted October 14, 2017 Sounds awesome so far! What distributor did you get? To set the timing correctly, you need to have the ECU in diagnostic mode. (Aussie EEC EFI vehicles, did NOT come with a SPOUT connector, like the American Fords did) If you're pulling codes, you must have some sort of code reader already I assume? If not, get one of Murray's code readers. They are truely awesome. Code 12 - is usually a stuck IAC/ISC valve, and/or a burnt out IAC valve circuit in the ECU (IAC = idle air control valve/Idle speed control valve - the solenoid looking thing, on top of the throttle body) edit - a dodgy MAP sensor can affect idle speed - solve MAP code first. Code 22 - an issue with the MAP sensor - which will definitely affect how it runs. (MAP sensor is the jigger on the corner of the header tank bracket, up near the firewall) Code 52 - ignore that, as an XG ute will never have Speed Sensitive Power Steering. (in fact, I wonder why that code is even there. Is it the original XG ECU?) edit - Code 11 - means everything is good Code 10, is just a separator code, denoting a pause, between displaying intermittent codes and hard codes. 1 Outback Jack reacted to this Share this post Link to post Share on other sites
Demmo 295 Posted October 14, 2017 reply to daves questions I purchased 2 fuel pumps a few years ago from "dirt racer" in qld I only replaced one on outback the other left in cupboard when it appeared to be faulty I purchased another which so far seems to be ok the oxy sensor was purchased about same time from repco but never installed distributor is bosc motor craft the sensor on the side has no brand this was sourced from local engine builder yes I have a code reader from murray but get a little lost with terminology the idle control valve may be faulty as I did clean it in thinners and I have since read this may be a no no so I may have to find replacement quick question are the icv the same on xh as the wires go into the solenoid on opposite side the map sensor was swapped from outback so it was running so can only assume it in working condition with regards to the old dist. it appears to have been filled with water as there was corrosion on the inside walls ect. so I guess this was also part of problem anyhow tomorrows another day thanks for everybody's input so far cheers demmo Share this post Link to post Share on other sites
Valvebouncer 2,389 Posted October 14, 2017 Ok just put timing light on and it is now showing the pulley market as about 1&1/2 cm pasts the marker when idles which was about same place before we changed distributor So do you think that it's too advanced or ? Think I better go have a beer or 3 and play with Google an not the redhead Cheers demmoSent from my HUAWEI LYO-L02 using TapatalkAs Dave said, it needs to be put into diagnostic mode. Putting a timing light on it when it is running normally ( not in diagnostic mode) is pointless as the computer takes over to advance and retard the timing. Essentially you set the base timing and the computer takes over from there.If I get time I'll take a photo of the process in my workshop manual. Share this post Link to post Share on other sites
Outback Jack 6,352 Posted October 14, 2017 Ok,ya 12 code... will be ISC solenoid, wiring to it or ecu faulty. Symptoms- rough idle or stalls due to lack of rpm. 22- map sensor out of range.If ya used ya xh one... dont think they are same... if not.... Map sensor faultVacuum leaksWiringOr ECU Symptoms-DetonationPoor performanceHigh fuel consumptionSurgeStumbles 52- its a power steering switch thing... XG dont have one..... lol. So most points to ECU..... Try using correct map... from xg.Also make sure there are no vacuum leaks on intake and pcv valve is working. If no go.. clean with carby cleaner or renew ISC solenoid. Carbon builds up. Still no go.... grab ya ecu code and grab one for $50 at a wreckers same. Still no go....trailer it down here and buy me beer princess..... lol.Only taking the piss mate... XG can be infuriating to get shit right... once it is.. Mmmmm. XG magic... Hang in there kitty! Jack. Edit... ya dizzy is right... you done it correct.To check proper timing... base timing There are two pins on the left of the diagnostics where you plug your code reader in.Top one is test , bottom one is earth.Alligator clip these two together and your in base timing mode when the ute is running and you can set timing to correct spot or check if out.Any other way.... your getting an advance-retard reading.

Demmo 295 Posted October 15, 2017 ya ho we are now in celebration mode all back to normal well nearly goes like the clappers except for the noise from thy holly exhaust o well it can wait a big thankyou to the guys who took the time to help and advise a big thankyou to the valve bouncer for pics now off to the pub for a wee dram or 3 and a counter lunch for the war office cheers demmo 3 Outback Jack, SPArKy_Dave and Valvebouncer reacted to this Share this post Link to post Share on other sites
Outback Jack 6,352 Posted October 15, 2017 Good onya Demmo!!Patience is needed with efi..... will shit you to tears .After you figure it out.... simples.You have now made an XG run good.... get a degree now.

I think it was several failures at around same time being failing fuel pump, possible blockage in the lines an filter, and dizzy cap wearing out causing erratic spark and of course a old impatient buggar with nil mechanical knowledge jumping to the wrong conclusions so hopefully she will give me another few years of daily travel of 200 kls a day thanks for your help along the way cheers demmo 1 Outback Jack reacted to this Share this post Link to post Share on other sites
