Lagged scores again. The idle up valve has also been known to fail in such a way as to aspirate PS fluid into the intake.

Adjuster: I've seen your filter setups before. They're very well done, as is everything you appear to do. The Rotella thing was my only gripe. Everything else you said is dead on and I can't disagree with your choice of methods or equipment. I prefer TP but that's a personal choice. The bottom...

No beef. We agree on way more than we disagree on but you're still wrong. I'm talking about the "blue bottle", Rotella Syn 5-40, not the 15-40 in the white jug. RTS 5-40 is a group III. It's not PAO based. Where are you getting that info? Do you honestly believe PAO basestocks could be included...

Sorry Adjuster, I know we've been here before and while it's obvious you're more oil knowledgeable than most people I'll repeat it again: While RTS is a great oil is it *not* a synthetic. It's a Group III. Calling it a "pure" synthetic is just plain wrong. The "thicker is better" thing is mostly...

Yep, sounds like rpm cut. Caused by a goofy or misadjusted TPS.

Lol, imagine how I feel? You're welcome to keep that distinction as far as I'm concerned ;) jdub: Yeah, funny how that happens. Looking back I realize I wasn't as brave as much as dumb. It's an old cliche but if only we knew then what we know now. These days I'm only scared of guys who type in...

Nothing scared me at 17 either ;)

Well, set it at 13.2 mm and see if the VF signal is in the middle range. Lots of cars idle a bit lean so it's no big deal. Besides, the lambda system (O2 sensor, ect) will compensate to a point. On an N/A car the screw effects idle mixture more than on the turbo because the AFM measuring plate...

FT, I think it's what was mentioned: some folks just tend to be more private than others. I'm one of them because I know how weird people (and the internet) can be. I've also seen the results of identity theft and it's not pretty. If it matters I live in California most of year and in Ukraine...

Not the right number. Look for a two digit code stamped next to the screw. For example, if it's 30 the distance bewteen the head of the screw and AFM body was set to 13 mm. 26 would be 12.6 mm. If the O2 sensor is disconnected the A/F ratio will go slightly rich. Rich mixtures surpress NOx...

What's the point? It's just a car. Maybe we should whisper "The red fish sails at midnight" when we meet? Hows about a secret handshake too? Besides, I'm wanted in 11 states ;)

You can wing it on the AFM screw by watching the VF signal. Best to set the screw back to the measurement stamped in the AFM body though. When you find the code post it and I'll decipher it for you. Not hard to do but eaiser than writing it all out. Btw, I just had mine smogged and before I took...

I'm not disputing that, just that of the half dozen or so I've seen none run more than about a third. I doubt his problem is coolant system related but I felt I should point it out anyway.

The People's Republic of Kalifornia. A more oppressive state doesn't exist. The weather is nice though. Stock cat? Hmmm....it's a good one. Should easily do the job and then some even with a slightly lean mixture. I assume it's new and not used. Verify EGR and be sure the cat's hot lit. Check...

Those numbers actually look pretty good. It's running a tad lean but otherwise the numbers show the engine control system to be working well. Course, they're taken after the cat so it's not a true picture of what the engine is doing but other than NOx they look pretty good. O2 is a bit high and...

You should see vacuum under light throttle. It'll vary from 2-15 inches depending on throttle but will drop off as throttle becomes either heavy or closed. If you don't see this remove the modulator and feel for exhaust pulsations in the bottom line. Test the modulator as per the TSRM. Since...

Code 12 is a lack of NE (Number of Engine revolutions ie; RPM) or the G timing signals to the ecu within 2 seconds after the engine has been cranked. It would be CPS or CPS wiring related.

1) The ecu runs the engine. It runs the efi system, the spark control system, and the idle system. Code 11 may or may not be the cause of your idle problem (likely not) but no ecu power means no engine operation is possible. If the car won't run or strands you somewhere idle is unimportant. 2)...
