X-F250 182 Posted May 24, 2017 Hey fellas,I'm having an issue with the Fairlane. It seems to be idling rough, a bit low and if you rev it lightly or try to hold it at about 1000rpm the engine stumbles and nearly cuts out. I tried cleaning out the throttle body, doesn't seem to have done very much. Sent from my SM-G930F using Tapatalk Share this post Link to post Share on other sites
351XD_Fairmont 604 Posted May 24, 2017 Do you know when it last had the fuel filter and/or injector filters done? Could be some are blocked up Share this post Link to post Share on other sites
X-F250 182 Posted May 24, 2017 Fuel filter was done when the last service was done at the start of last year, but the old bloke parked it immediately after it was done. The service log recommends cleaning the injectors but I don't think it was ever done.Sent from my SM-G930F using Tapatalk Share this post Link to post Share on other sites
dex 2,065 Posted May 24, 2017 Mine did that ,, blocked muffler sounded like a cyclone out the tail pipe ,, " when it did start and idle " Share this post Link to post Share on other sites
351XD_Fairmont 604 Posted May 24, 2017 I'd start with the injectors then as mine was running a bit rough before I did them, check the intake track and exhaust system aswell 1 X-F250 reacted to this Share this post Link to post Share on other sites
X-F250 182 Posted May 24, 2017 Mine did that ,, blocked muffler sounded like a cyclone out the tail pipe ,, " when it did start and idle " Exhaust noise on mine sounds normal, although on start up I sometimes have to give it a few revs to get it to idle. I'll check the injectors, they seem to be the likely culprit. Sent from my SM-G930F using Tapatalk Share this post Link to post Share on other sites
dex 2,065 Posted May 24, 2017 First up be plugs , then if efi unplug the green plug and check timing ,, mine was " surging" on acceleration ,, worked out i was setting it at 10 deg ,, with the green plug connected ,,, was always 12 deg out Share this post Link to post Share on other sites
X-F250 182 Posted May 24, 2017 Is there any trick to getting at the dizzy? It's a pretty tight fit in there.Sent from my SM-G930F using Tapatalk Share this post Link to post Share on other sites
Thom 6,651 Posted May 24, 2017 Pull the airbox and isc off gives you more room 1 XTREME KARTS XF reacted to this Share this post Link to post Share on other sites
XTREME KARTS XF 1,212 Posted May 24, 2017 Yep, as what @Thom said. Also take the cap and rotor off before taking the distributor out Share this post Link to post Share on other sites
X-F250 182 Posted May 25, 2017 Once again, you blokes have saved the day. Bumped the timing up a little bit and now the hesitation is barely there and it doesn't bog down under load. It still drops off for a moment if you very lightly touch the pedal, but I think that might be the injectors.Sent from my SM-G930F using Tapatalk Share this post Link to post Share on other sites
Outback Jack 6,352 Posted May 25, 2017 Whack a bottle of injector cleaner in her and take it for a good run... will clean her up... all good. Fuel filter will of kept the rail and injectors clean enough.Sent from my GT-S7583T Share this post Link to post Share on other sites
X-F250 182 Posted July 17, 2017 Aaaand It's started back up again. I've been driving the old man's ute since our roady bloke has been on holidays. Went to get the 'lane ready for inspection and ran a bit of Seafoam through it just to be safe. Let it run for a while and it started to get shuddery. Fuel pump was also whining a bit, so I figured it might be the pump on it's way out. Swapped it for a spare I had, and as I was doing it the fuel that came out of the line was a really dark brown, almost like Vegemite. It had a quarter of a tank when I bought it and I've only 5L of fuel in since then. It sat in the previous owners garage for almost a year before that. Any chance it's just some pretty crappy old fuel making it run badly? Sent from my SM-G930F using Tapatalk Share this post Link to post Share on other sites
Outback Jack 6,352 Posted July 17, 2017 Yes. Drain tank, but you also need to flush the lines until the fuel filter.... with clean fuel, after its the right colour.... new filter... new pump with filter sock.Something has contaminated the tank, clean completely before refill.Ive had cars sit 10 years and not do that.... just fuel gets stale.You just stirred up all the crap in the tank with 5L. Good luck. Jack. Sent from my GT-S7583T using Tapatalk 2 Valvebouncer and X-F250 reacted to this Share this post Link to post Share on other sites
