It was the master cylinder for the clutch. All good now

Ive got a 2000 gu ZD30. Been doing NADS. Have egr block, dawes and needle valve, pyro and boost gauge. I've been playing a lot with it so I'll list the events in chronological order. Firstly the engine light kept coming on and/or going into limp mode. No NADS fitted yet. Mostly on highway. I replaced MAF sensor with a cheap ebay one. (Mistake). Seemed to fix the problem but now blowing black smoke. Sometimes going into limp mode. But much better. Next step was fitting gauges. Boost and pyro. Then fitted dawes and needle valves. Set up according to the page I found on this forum. Stopped the over boosting and limp mode. Still blowing smoke. I figured it might be the cheap maf sensor. Fitted egr block. Everything else was ok.. so i thought. Went skiing/camping with the missus and a mate, driving down the highway starting limp mode again, then engine light. Kept switching off engine and restarting to reset engine light. Struggled all weekend but got home. Nearly got divorced cos the air con hasn't worked since I bought the truck 8 months ago. Lol. So booked truck in to auto elec to get that sorted. He had it all pulled apart and diagnosed but I needed it back cos I travel for work. So he put enough back together so i could Have it for a week. I noticed a lack of power and exhaust Temps getting quite high. Some hills I ended up at 60ks an hour which I've never had to do. Thought it was strange. But it was late at night and needed to get to where I was going. The road I drive to work on is horrible and bumpy. I Even had to get the windscreen replaced cos a stone chip cracked the whole thing from the road. I kept having trouble with engine light and sub tank light coming on. Figured out the stupid battery terminals were falling off the battery from all the bouncing. I temporarily fixed it to get me home till the auto elec can replace the useless terminals that were on it when I got it. That fixed the sub tank light and I thought it maybe had something to do with the problems I had before I fit the NADs.760 bucks later the air con works. I needed a new condenser. Still struggling for power. So I put the old MAF sensor back in this week and no more smoke and no limp mode and no engine light. But still no power. I've played with the needle and dawes valve for the turbo but no change. I'm now struggling to get to 120kph. It used to be pretty easy. Serviced and new air filter 2000ks ago. I do about 3000ks a month just for work. I've blown a gasket on the egr pipe after putting in the block. Just took the block out and test drove to prove it wasn't because of that. Still no difference. Egr block back in. I noticed today though that radiator cap was leaking a bit. I topped up coolant and fixed radiator cap. Not sure if that could have anything to do with power though. So now I'm stuck. No limp mode. Battery terminals fixed. Not getting hot. Not blowing smoke. Air con is great lol. But still no bloody power. 4 hours on the highway twice a week is bad enough with out having to deal with this crap the whole time. The truck is for sale cos I'm changing jobs and moving and traveling so many ks in the patrol is not good. But I can't sell it if it's not up to scratch. I can't leave other people with this problem. Anyone got any ideas. I need to get rid of it as soon as I can. Or at the very least get some power back so I'm not ready to kill someone when I get home. Any help and suggestions would be greatly appreciated. Thanks guys

Just wires going through the fire wall. The boost sensor is still in the engine bay

There was a blown gasket on the bottom part of the egr pipe, Such a pain in the arse to get to. All done though. Worked ok. Boost gauge isn't reading properly now though.

NADS

Hi guys. Got a strange one here. Have owned the truck just over 3 months and slowly overt the last month or a little more it had been getting really difficult to get into 1st 2nd and reverse. At first I thought it was maybe syncros but it was 3 of the gears all around the same time. Also I found a receipt in the glove box for a full gearbox rebuild and clutch replacement 2 years ago less than 30,000ks ago. I've bleed the clutch a few times now and while the clutch feels a lot better the problem has not improved. It feels like the pressure plate maybe cos when I stop and leave it in gear I can feel the truck want to crawl forward like the clutch hasn't fully disengaged. It looks as though I've got full movement from the slave cylinder but I never really checked it out before I had the problem. Surely the clutch isn't stuffed so soon after being replaced.

yeah i don't think the two are related but they just happened to be at the same time. Not sure if it was limp mode, but i had no acceleration, and lost about 50km's an hour before i got any power back and even then it took a long time to get back to 110km/h. haven't had the power loss problem since.

Hi guys, Was cruising down the highway minding my own business (2000 model ZD30) and she must have over boosted or something and went into (i'm assuming) limp mode. Had no acceleration and lost most power. anyway, after getting back to normal my speedo just starts jumping all over the place. Not in the mood to worry about it, i just go off the GPS to get me the rest of the way. So now i've been driving around a while i've found out the symptoms. It appears that driving up to 60km/h is fine, but anything over 65ks and she starts jumping all over the place again. I'm not so fussed about it cos i know what revs i need for what speed etc but it gets annoying and I have rego in a few months. Anyone else have this problem and/or know a solution? Thanks for your replies. Andrew
