    1UZ EGR delete - resistor install with 6-pin connector (temp sensor integrated?)

    Gents, trying to help a customer who deleted the EGR system on a '93 LS400 and is suddenly getting a CEL. (click for larger image) On the 25620-50020 EGR valve (for 93-94 SC400 or 92-95 LS400) with the 6-pin connector (pictured) is the temp sensor integrated into the valve? I'm familiar with...

    What to do while waiting for my EGR delete kit

    Hello, Today I started the engine of my LS 400 after 2 weeks of work. But... the engine doesn’t run well. Last week I removed the gearbox to change the rear main seal. My EGR pipe was in bad shape so, without the gearbox, the access was easier and I removed the EGR pipe. I bought a EGR delete...

    What can I DELETE??

    Have a 92 1UZ to swap into an Izusu trooper. I'm in Florida with zero cause to use any of the emissions stuff and I'll be using the Isuzu manual transmission. One thing that struck me when pulling the engine from the sc400 was how much crap was bolted to it! Modules here, modules for this...

    EGR removal

    Hi, I've removed the EGR system from my 1uz and blanked all the lines etc. I note that you're supposed to install a resistor to stop "MIL" triggering. Does anyone know the connection point, why it's needed and what value resistor is required. Thanks al

    EGR transducer

    Hello all. First time here. I have just bought a 91 LS400 with about 200,000 miles on it and it has failed a smog test. NOx was too high. HC and CO levels aren't even close to max. It has fault codes for TPS out of range and an EGR transducer which makes sense. No EGR = hi NOx. Car runs OK and...

    EGR Tube from exhaust removal

    I cannot remember since I have been under the car. Can that rear egr tube from the exhaust manifold to intake manifold be removed without pulling the motor? I know there is 1 or 2 random bolts that hold it to the engine... can they be easily removed? Matt

    Rear coolant bridge question

    I got a quick question on the routing of EGR and coolant on the rear bridge. In the picture below, are my assumptions about the functions on that rear coolant pipe correct? does the stock EGR pipe run straight to the manifold and something else go to those egr ports. When I got my engine, this...

    EGR Pipe

    This is the most common site where the EGR pipe breaks. If this occur you will noticed some exhaust leak and perhaps CEL (check engine light) would turn on.

    Removal Of The EGR System

    To all the American SC400 owners, Re: EGR system fitted to the American cars. I know very little of how the system works or effects the ECU ? Considering i am an Skip with a Soarer this would be expected. What i am looking to find out is how the EGR works and effects the engine, if it...
