A smoke machine pressurizes things with smoke. Leaks in the induction system, vacuum lines, exhaust system, under dash lines, almost any leak in a sealed volume can be quickly found by looking for the smoke escaping. Some even use smoke that glows under UV light. They're a very handy tool. The...

The lambda sensor is monitored three different ways (all of which will turn on the MIL) so if it was at fault you should have some codes. Plus the engine will run only slightly rich if the sensor has a problem or becomes disconnected. It's important to remember the ecu doesn't just whack out...

Man, are those things handy huh? I built one. It's a great tool to have.

120K is pushing it and then some. You can test in either in or out of the car but with that much mileage it's way over due for replacement. Don't be surprised if replacing it doesn't solve your problem though. Are you getting any codes?

Makes no sense. There should be a hole in the banjo bolt to feed the rail. The dampener just screws into the end of the rail to provide a spring loaded volume. It sounds like you're referring to the fuel pressure regulator, not the dampener.

Gotta agree with the others in that it sounds like pirate air. The AFR should always be right around 14.7 during steady state cruise and idle. Some engines idle just a tad leaner but not very much.

It provides no restriction Jake. It's really nothing more than a tiny hydraulic accumulator. Too much of an increase in fuel pressure will reduce it's effectivness though because the spring is calibrated.

I wouldn't call it useless or even over engineering. It's an example of proper engineering, of Toyota doing things "right" to a fine degree. As Nick said, it's there to dampen the jitters in fuel pressure caused by the injectors opening and closing. You can't see them on a fuel gauge but if you...

Good post mrnick. Concise, coherent, informative, and accurate. I never thought I'd ever see anyone mention cavitaion erosion on this forum ;)

Nick's advice is dead on wardog. The car has a low pressure cutout switch to prevent the compressor from running when the refrigerant is low because the oil in the freon won't circulate and the compressor will burn out. Not saying that's your problem as there are other things that'll keep the...

Don't be putting a new cat on without solving the rich mixture problem first or you'll trash the new cat. It make get you to pass but it'll be working so hard it won't last long. Lol, Bob and Doug were a hoot alright. And speaking of trailer parks it could be worse. You could be living in...

Lol, I thought that was pretty clear. Must be my sarcastic meter is well caled ;)

There's gotta be a bazillion places that do it. It's common in both the autmotive and aviation industries. Search on "torque wrench calibration". Last time I checked if you send it out it'll be around $25 or so. I cal my own because I work on aircraft. You can often get calibrators for cheap on...

Lol yep, good eye. The stainless steel is sort of a dead giveaway too ;) *edit* I see you're from the UK where the D fiasco is probably burned into the national consciousness. Don't blame me, I just own one ;)

Allan: Yeah, it's coolant. Donaldson bypass. There's also an oil bypass filter but you can't see it in those pix. Group: Yes Sir, that's a DMC 12. A 1981 model. Near pristine. The pix are a few years old. The Snap On stuff has been replaced with better but the D car is still around.

Compared to some I'm almost embarressed to show mine. It runs flawlessly though. Here it is getting it's twice yearly checkup.

Why not just send it out for cal? Cheap and effective.

"Just" drop the starter? ;)

Huh? What are you babbling about? I like Canucks, especially BC. Hell, I'm 50% Canuck myself. I'm just pulling the guy's leg a little. I think he knows that. That said, anyone who drives their car around from day one with the MIL on shouldn't exepct a whole lot of sympathy. But I'm still trying...

The ECU sends out 5 volts to everything so I doubt it's at fault. Has to be wiring or the AFM itself. Can you get the engine to run at higher than idle by holding the throttle plate open? Will it run with the AFM unplugged? It should. Remove your EFI fuse for 30 seconds to clear all codes and...
