I find that my car is getting a bit sluggish and feels like it has lost a bit of power. When I first got the car and revved to the lift zone the car pulls hard. Now it feels like the engine struggles when it reaches the lift zone.

Is this because i didn't run the engine in as i should have. Coz i started revving it to the **** house after 1000km's.

Plus i get a knocking noise when it is idling coming from the engine. Sounds like the timing is out, the valves might need to be adjusted again.

The temperature seems to make a big difference as well.

Nice cool morning the car is awesome - but the middle of a hot day

(over 30 deg) it doesn't pull anywhere near as hard. Anyone else found this?

Wonder if the CAI helps on the really hot days?

yeah temperature makes a massive difference as you pointed out, as for me when i drive i do not use lift and usually keep the car at lower rpm during those crazy thirty to forty degree days when its boiling. I cant imagine its healthy to rev the car to 6-8krpm for lift during that heat, so i dont do it.

Also do warm up your car, wouldnt believe how many celica posts ive read where people have complained about lift disengaging in the morning. the car has to warm up before it lets u engage lift and people are trying to hit lift within minutes of a cold start lol.. :blink:

I saw a blue sportivo corolla in stclair the other day as i was passing through, it looked quite nice

Yeah...I always warm up the car first every morning.

Also the fuel could be a factor. I use Optimax.

What do u think the best fuel is?

How long do u have to run in the engine before u can start revving it hard.....coz i started revving hard after 1000Km on the clock. I also revved it as soon as i drove it out of the dealer. Do u think that could have stuffed it a bit?

There could be your answer mate, be careful which petrol station you use Optimax from. I stopped using it after my third fillup because the fuel was shoit, so ever since im pouring the 8000 synergy, so far no problems.

yeah its one of those things, mobile and optimax are suppose to be great, and generally they are but believe everyone (like above : ) when they say that it can vary from servo to servo..

If u want to try something different use Caltex Vortex (its Premium of course) or BP Ultimate (which is suppose to be 98 Ron - a slightly higher octane level than normal premium...suited for performance jap cars such as the rex)....

I agree with Lucio,I started using Synergy 8000, only because that was all I could buy at Cremorne on Friday night and have found this to be the best. :D

put in some synergy 8000 as it will clean the engine as well as run better.

optimax is ok, but if u leave it for a while it will gel up so some servos will have sh*t optimax... thats y i never use it. prefer to ALWAYS get good petrol instead of sumtimes.

also u must have really pushed ur car hard to f*ck it up so quik.... if u didnt push it close to racing conditions then u have nufing to worry about.

and BP Ultimate or Caltex Vortex are not higher octane level then optimax or synergy8000. from what i kno they are all 98ron, but i heard that BP Ultimate was lower.

caltex vortex: With an octane rating of no lower than 95, and in some markets 96, will satisfy the Octane needs of most cars in Australia. - caltex website

i dissagree with that statement.

i recon we need more octane. in japan they got 103 octane from the pump!!!

here our supercars use 98. dosnt say much about our fuel.

it does acctually, u should try it. its not really worth it running ur car with octane booster in it all the time as its not very cheap(compared to fuel prices - itll make a tank of fuel at least $15 more expensive). but it dose make a noticable diff.

      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!!! :)
