    So currently, I’m trying to pull my engine and transmission, as after researching (and realizing the bolts are kissing the firewall) there is no way to just pull the engine on its own; I’m currently stumped on how to get the intake manifold off in the car, so my main question is, if i should or...

    GS350 vs IS350 engine harness So, I recently purchased a 2009 is350 with "electrical problems" they reportedly did an engine swap with an 80k mile engine. And they said they lost the computer that sits next to the ECU. Come to find out, it was just a plastic junction point that was missing. I...

    I just replaced the coil packs, spark plugs, and wires. I noticed a small random metal hose that comes off the side of the head. What is this for? And should there be anything hooked up to it? thanks JMperformance

    I recently got a P0440, P0441, and P0446 codes and after clearing it, came back a day later.

    Hi, I’ve recently started getting issues with my is300 starting to struggle to pick up speed with the rpm jumping up and down on acceleration, I’ve changed all spark plugs and cleaned the throttle body but it still continues to do it. If anyone knows this issue please let me know, cheers!

    This engine is literally Satan and looks basically brand new. Every part; cams, valves, lifters, VVTi gear, etc. On the way back home a valve or 2 got stuck again. Its a never ending cycle, and I'm sick of this bull####. No codes, no nothing, can't find anything wrong. Purrs like a kitten,and...
