had consistent eng light / limp mode after 5 secs of taking off - not overboost as it wasn’t going over 16psi , but i checked all boost hoses & clamps anyway , tried 3 other MAFs off other vehicles that were running fine but still same problem , fitted brand new genuine MAF but no change , disconnected MAP sensor thinking it may have been playing up & falsly giving overboost reading causing limp mode - no change , i thought tank breather may have been blocked & creating a vacuum in the tank so when it happened i pulled up & opened the fuel cap but no air / suction was evident - fitted a better tank breather anyway because the standard set up is a joke . I’d had this issue years ago when i bought it & turned out to be a blockage in the filter housing so i’d replaced but thought it might’ve happened again so i bypassed the filter & plumbed the fuel line direct into the injector pump - not ideal i know but i was getting desperate - but no change. i’d fitted a carter lift pump & all new fuel lines & clamps a few weeks ago ( issue was there prior to this ) so didn’t think there was an issue there , anyway i plumbed it back through the filter housing & put a bit of clear hose from the filter to the injector pump & WALAA !!! air bubbles in the fuel . Now as the problem was there prior to replacing all fuel lines i hadn’t thought the problem was there until i saw the air in the clear hose . Anyway i removed all the new lines & wiped clean all the barbed fittings with a rag then refitted them all & NO MORE AIR BUBBLES !!! , anyway the eng light / limp was still there 😤😤😤 , i loosened the bolt on the return line & ran the lift pump for a few mins to bleed any air out , went for a drive & 5 secs on came eng light & limp mode 😤😤😤 anyway i drive it around & turned it off then started it & drove around again about 3 or 4 times & bugger me it came good . un f@#kn believable. i’ve done about 200kms today since & touch wood no dramas yet . So at this stage i’m assuming there was air getting in the fuel somewhere & after i replaced the fuel lines thought it mustn’t have been that & was resigned to the fact the IP must be rooted but after i did everything else i put the clear line on it showed that was the problem . how’s that for a mini series explanation.
after i typed all that it said ‘ post quick reply’ which didn’t seem appropriate but there wasn’t a ‘post long winded description ‘ button haha

Frustrating stuff mate! Had the worlds tinniest fuel filter hole years back on a TD42 that only sucked in at T intersection idles after hot highway long flogging stretches. Took a dusty dribble spot to find that prick :-)

Had the battery spew acid all over the tray, body and chassis. Washed it all down 3 times with hot water and bicarb to get it all neutralized . Scraped all the crud off and sprayed fish oil on the affected areas. I spoke to the paint professionals, and they recommended getting it all paint stripped and sand blasted, but it will have to wait until funds permit.
I am pretty confident the fish oil will be OK as I cleaned and sprayed some on the tray in the first couple of weeks of getting the vehicle back in 2012. It was still in pretty good nick after all that time.
Craig, don't worry about it a further second. You have aggressively diluted, then neutralised and finally sealed the active surface from oxidation. You will be OK, Don't go the blast and repaint, simply not needed. Once the fish oil has dried up, a good undercoat then top coats - all good. I work in a heavy industrial acid plant and know a bit about corrosion and protection.
Reconnected the rear anti sway bar and stiffened up the front shocks. Doesn't feel like a boat in a high sea anymore :-)
