Just drive the car for 15-20 minutes to get the engine up to normal operating temp. Then unplug the ECT (an OBD-II term btw. CTS is the older term) and see if the idle improves. If it does change the sensor. If you want you can test it while it's out to confirm it's bad. In either case clear the...

Sorry, keep forgetting you're N/A. That's the way it should be plumbed. The turbo guys often block the TB line and run the can only to the accordion. Lol, they're apparently operating under a misconception there's vacuum on that line. The water you're seeing in winter is condensation from...

That's odd. Anyway, with a stock PCV system and a healthy engine you shouldn't see more that +.2 inches of water in the valve covers. Usually it'll be zero. Same in the crankcase. I hope you have that catch can hooked up properly. I see a lot of them plumbed only to the accordion. That's bad. It...

What is the voltage across the battery when this happens? If you're supplying adequate power and control to the starter (and it sounds like you are) then it has to be the starter itself. A lesson in always testing new parts prior to installing them.

.....and BHGs ;) EGR can be active at times other than steady state cruise but never at WOT or idle. During a heavy load like climbing a hill at less than 4200 rpm (it's cut out point) for example. That's when not having it can bite but as long as knock control is working everything should be...

The sole purpose of EGR is to suppress the formation of NOx. Recirculated exhaust gas is composed mainly of CO2 and water vapor. It may be hot but it results in lower combustion temps because these gases are inert to the combustion process. Since they displace atmospheric oxygen in the charge...

Oops, you got me there cuel. Turbo on the brain. Yeah, it's not quite the same but close and integral to the dizzy. Works the same way as far as diagnostic and fail safe modes go.

You mean the Karman pillar? In theory yes, if you're careful to glue it on straight and keep the passage clean it should work. Remember it has to fit in the hole at the bottom of the flow meter housing. Nothing to lose by trying. Use some two part epoxy but go very sparingly with it. You can't...

Yeah, filters are going to load up quickly. The wool should drain to the bottom of the can though. Funny, I've never used a can because I get very little oil in the intake. Maybe you have too much blowby. Have you measured it with a manometer?

Good deal. What they say is true: "Each of us knows something...together we know it all"

First Supra I've heard of with a built in bong ;) Try stuffing the can with stainless steel wool or plastic kitchen scrubs. That'll give you two types of separation. The first will be inertial or "torturous path" separation ie; the air can make the twist and turns through the wool but the oil...

Well, I hope the 89 wiring is the same as your car. JB #1 is behind the drivers kick panel. The big one. The ground for those circuits is on the mounting bolt. That the seat is working shows at least some connection there. Check for continuity between the white with black stripe wire on pin...

It's good to outgrow the "get a bigger hammer" school of doing things. Not only fewer broken parts but it cuts down on the bleeding too ;)

Yep, looks like the main ECU (and a few others) ground point. I can see the wires in the photo. Thanks. Maybe that's why his battery is dead ;)

Which switch did you buy? Which window is the problem? If it helps any other than the 30 amp CB the locks and windows share nothing in common. The windows are the easier circuit of the two so start there. Based on the leds doing what you said it sounds like the driver's side switch is goofy...

All depends on how much care he takes. The problem is inexperienced people haven't had time to "calibrate" their muscles. It's why they often break stuff. People with experience "know" how to apply torque consistent with the material and size of whatever they're dealing with. They also know...

So this stellar example of maturity and driving skill will be getting a bike. A crotch rocket no doubt. Dead man walking...

The reason I asked is because iirc correctly that's where the main ECU grounds go. My car isn't nearby so I can't be sure. Maybe someone else will chime in.

The problem with that approach is most people would take advantage of it and not do the repairs. This guy has cheated twice for example. Cheating only forces the state to toughen up the regs even further. That's what happened in California. Because of fraud it's all automated these days. This...

Does the car run? ;)
