Hey guys, I have a 1996 Hiace with 230k on the clock. I have had this van for 5 years now and have had this problem since I got it, have taken to several mechanics and no one has been able to help. Hoping someone here has had the same problem and could offer some help!

Living in Melbourne this issue doesn't happen that often but on a warm day, say 28 degrees plus, I hit the highway and the van will start coughing and spluttering, it feels like it's choking, loses all power and shakes the whole car, this will happen for a few minutes then will come good again. Usually this will happen every 15 minutes or so. Temp gauge is at normal but for some reason this only happens on hot days. If anyone can offer me any advice and solve this problem I will buy you a bloody beer!

As I type this I'm currently sitting at a servo waiting for the temp to drop so I can drive home! Hahaha

The fuel could very well be boiling in the float bowl/vapour locking.

any idea on how to fix it?

In short, by keeping the fuel system and carby as cool as possible. If you Google fuel boil or vapour(vapor for American examples) lock fixes, you should find some helpful answers.

You can try to cool the lines, pump and carby with some cold wet rags. That should give you an indication.

      Disconnecting winch, lightbar and UHF

      Generally, yes. In the 60s, and earlier, there were cars with positive grounds, so I'm always a bit hesitant to say the negative wire. It is always the one that bolts to the body. Herb

      2011 Land Cruiser 1VD-FTV Engine Won't Start After Overhaul

      Hi everyone, I have a 2011 Land Cruiser VDJ200 with a 1VD-FTV engine. I recently had the engine fully overhauled due to a blown head gasket. However, after the overhaul, the engine is not starting. It only cranks but doesn't fire. I've checked the following DTC codes: Internal memory EEPROM error Low rail pressure The actual rail pressure data shows: 240 bar during cranking 61 bar when ignition is off Based on these findings, I suspect the following potential causes: =Defective Diesel High-Pressure Pump =Leaking Piezoelectric Injectors =Diesel Fuel Bypassing to the DPF Circuit =Faulty Injector Drivers I'm hoping for some expert advice to help diagnose and resolve this problem I'm seeking expert advice on how to troubleshoot and resolve this issue. Any suggestions or guidance would be greatly appreciated.

      Disconnecting winch, lightbar and UHF

      Disconnecting batteries, ALWAYS disconnect the ground wire first. Doing this will also disconnect power, in general. Herb

      Disconnecting winch, lightbar and UHF

      Hey guys, I’m wanting to disconnect my current winch, lightbar and UHF as I have new plans. I’ve installed a winch previously on another car so I get it’s a case of following the cables and disconnecting from the battery, etc but but safety wise, should I start by disconnecting the battery so the cables aren’t live orrrr? And if so how do it go this haha?

      Snapping wheel and axle studs

      Put a set of standard wheels on it and your problem will disappear. It is critical that the hole in the wheel centre is a snug fit on the axle boss (without wheel nuts fitted). If your wheels are sloppy on the axle boss this allows excess force on your wheel studs and they will break, as yours are doing. If you are unsure of what to do, go to a reputable tyre shop and get assistance.

      2zz idle / roughness when accelerating past 3k

      Hey everyone was hoping someone might be able to point me in the right direction with this issue I've been facing for a while now. My Celica's idle will drop down to almost 200rpm when stationery after hitting operating temperature. Pretty much feels like it's about to stall out but never actually does. When taking off from a set of lights it almost feels like it hesitates or is down on power and then all of a sudden it lurches forward and gets a boost in power again. Then again around 1,500-3,000rpm it feels down on power and in what I can only describe in the engine feeling scratchy. Past 3,000 rpm it gets a little boost in power again but still definitely feels down on power compared to what it used to be and still has that roughness. Note lift is also not working at the moment but I have changed the lift bolts, planning on cleaning the VVT and VVTL-i OCV's New engine mounts have been installed I changed the MAF sensor about 4 years ago albeit not OEM. After doing some research my main ideas now would be a New MAF this time OEM, TPS, IACV or Coil Packs (Changed plugs 50,000km ago) Any other suggestions would be greatly appreciated!!! :)
