    Hi all, I've got a bit of a weird issue with my 3sge sw20. My idle is really high at the moment, approximately 2k rpm. I've fully cleaned, sealed, and clocked the IACV but to no avail. I have no vacuum leaks whatsoever and when I put my finger partially over the IACV, I can get the idle to...

    Hello everyone!, I have a problem with my MR2, 600km after overhaul and refueling to full (?idk) I noticed strange behavior of RPM gauge. My idle is something around 500-700rpm on gauge (before overhaul it was similar). Unfortunately, in addition, there appeared RPM fluctuation (video) BUT...

    Would anyone have the body harness diagrams for the 93 3sge and the gen2 3sgte. I'm swapping in a turbo engine and the body harness connectors are totally different and I'm trying to figure out what each cable does.

    Hey guys first post here, I've got a '93 SW20 that has never revved past ~5,800 rpm for as long as I can remember. The car drives fine otherwise and has never really proven to be an issue as it doesn't get driven hard often. I have been looking for a solution on and off for a while now but I...

    I bought a O2 sensor from a local provider to safe some money by not having to import one. The thing is that it has a male connector just like on the car's (SW20 3SGE) wiring harness and they don't have any other variants for sale. So does anyone know of a square (2x2 pins) male to male adapter...
