Just playing with ya Colin. Fuel pressure has to change in order to maintain a constant delta P between rail and manifold. In a stock 7M it's 36 psid.

Well, kinda. Sort of. Not exactly. It actually stays the same. It has too or accurate metering would be impossible. That's what the word "regulator" in fuel pressure regulator is for. I understand you're talking about PSIG but I don't want others to get the wrong impression.

^ lol. Man, I wish I had your patience ;)

After precisely tuning it my Lex runs around 20 hz at 48% duty cycle @ 650 rpm. There's no way anything near that will be 4.8 vdc. He needs to either use a scope or just go ahead and replace the AFM. I can tell you from running the engine off a frequency generator in place of the AFM (while...

The problem is he's in Cali, a place that prohibits the importation of even *new* 49 state cars. As for direct import non federal used cars there's California Health and Safety Code Chapter 6, Section 44200. And that's just the beginning of his troubles. This kid better have a very fat bank...

Sounds like a bad clutch bearing. You can replace just the clutch but if the comp has lots of time on it replace it before Black Death comes a callin'. Less hassle and you end up with a new clutch and shaft seal, a common leak spot in even well maintained systems. Or rebuild it yourself. The...

Yeah, this is gonna be good.

^ Thank you. Power to sensors is 5 volts and the normal range of "legitimate" signal return is from 100 mv to 4.8 vdc. This 5 volt level for power and signal one of the things that distinguishes a TCCS from conventional EFI. The "crappy-ass" TSRM also shows how to check voltages. It's the best...

Edit: Sorry, having a bad day. Is it too much to ask people behave when traveling? It's not my fault shit happens. People need to relax. You'd think they'd understand it's either that or go to jail but no... Either punch through the wire insulation with a pin/needle or back probe the connector...

The AFM electronics has two sensors inside. One measures air flow and the other measures temperature. These two sensors are electrically and mechanically independent of each other. They also have their own codes. The part of the TSRM that refers to changing resistance with temperature involves...

It'd serve you better to measure the part of the AFM that actually produces a code 31 and not the other part.

It's normal. The TCCS keeps the MIL illuminated until rpm reaches 500 at which point it gets extinguished. Thereafter whenever rpm falls to 200 or below the bulb burn out check is automatically reset and invoked again. There's actually a lot more to it but that should be enough to answer your...

Let me make it clear yet once again: A thief is a thief. Period. I make no distinction between corporate thieves and "the bottom of the food chain". They're all scum. Theft is morally and legally wrong. Your defense of the other poster's immoral and illegal behavior as "Right. Period" is...

Nah...it's because Leon's boat in Egypt is closer to Oz than it is to where I am ;)

Bad news: A good compression test in no way rules out a BHG. edit: IJ beat me ;)

That would be altarboy. And it doesn't matter what others do. It matters what you do. A man is what he does when it counts. It's pretty clear what you are, which is why I typically ignore you. Now that you've given yourself enough rope I'll be doing the same while the hanging commences.

Perhaps I wasn't clear enough. A thief is a thief. Period. If you take rightfully owned property from someone that was not offered to you you're stealing. Doesn't matter if you sell it or not. Doesn't even matter if you derive zero benefit from taking it. Doesn't matter if it's ideas, music...

IJ: Yeah, plus his oil temp at that level would've driven viscosity. Doesn't sound good. There may be some hope though. I know of a GTE that was driven on the highway without oil until it seized. It went another 40K miles after that with nothing more than a slight ticking in the valve train...

Ian, that's exactly what I was thinking. It's possible when the three quarts were lost pressure was lost at some point for a brief time. If so that may be what's come back to haunt him. I'd still ID it though. The oil pressure seems fine. I get the same readings and I have what must be the...
