    Headers on 1FZ-FE engine 1997 Landcruiser

    I would say improved seat of the pants performance but not much MPG improvement. I went with a 3" custom exhaust and kept a single cat. Intermittent CEL for lean condition. Currently no CEL! CXRacing headers will delete your EGR! There is no channel cut for the #6 exhaust to port to the...

    What;s THIS wire for?

    I know you were asking about the wire on the left. I just grabbed a picture from a different thread that showed the same general area, although highlighting a different wire. The wire you circled in blue may be A23 Air Mix Control Servo Motor or W5 Water Temp. Sensor. Connections are...

    LX450 AC urgent

    There is a cut off for the AC when the coolant temperature goes above 226'F / 108'C. The stock temperature gauge is not that helpful. Any temp between ~150 and ~230 does not move the gauge. The purpose of the AC cutoff is to protect the engine but it is at the expense of the cabin comfort. I...

    No start - weird electrical problem

    I don't see the heavy gauge ground cable that should attach to the engine block. I only see the light gauge wire going to the left front quarter panel. The heavy cable should come through the hole in the battery enclosure right behind the negative terminal. This will give you a large...

    Headers on 1FZ-FE engine 1997 Landcruiser

    My CRX headers are coming up on six years old. I still love the exhaust sound on startup. The only issue was early on with the nuts and bolts where the 3-1 pipes were connected. The lock washers lost their tension due to the heat and vibrated loose. This is above the section of flex pipe. I...
