It's "which" btw. One free get out of jail card is all you get...

No.

Spend a little more and use real aviation stuff. Aeroquip AE701 is a better hose than 601. 666 is teflon lined and impervious to all fuels, oils, alcohols etc. If you don't want the SS braid use 303. None of these will permeate fuel through them. AQ isn't the only one who make MIL-H-83797 hose...

Thoughts? Three: 1) Listen to gte. Smart man. 3) Dearly beloves deserve the best of everything. Otherwise they're not dearly beloved. 3) If a 20 year old car is your dearly beloved you have bigger problems than a radiator.

The CEL isn't supposed to come on in ACC.

Well, the mighty shaeff's words in the first paragraph of that link stand on their own merit. What part of "it's essential to bypass or drill out the stock j-tube" didn't you understand? You can't install a high flow pump without opening up the J tube or the pressure in the fuel system will be...

Hmmm. Someone is confused. Could be me I suppose. The turbo Supra uses low impedance voltage controlled injection. P&H injectors are current controlled and never have a current limiting resistor pack as part of the system. There are Toyota engines of that era that used peak and hold control but...

Since you asked nicely ;) Code 25 is because the O2 sensor stopped cross counting and stayed hard over for several seconds. Fuel pressure could indeed be one of many causes. What is Vf at idle? Not sure what you mean by the J tube being "blocked off". Did you leave it as is when you installed...

I've used it since day one. Wheel goes up when I get out, comes down when I get in. Been doing it so long it's automatic. When I pay for something I use it ;)

There's a lot more to know about it but those basics are a good start. They're old news to anyone who has done aviation maintenance where certified AN is as common as dirt. We've also better hose choices in aviation. Teflon lined with integral fire-sleeving comes to mind. While there are torque...

Berryman's will do. Just enough to submerge the crowns. Let it sit overnight if you can so it gets down into the ring packs. Don't get your hopes up. A dysfunctional TPS would only cause high HC during decel but your problem is under load. However if timing was previously set with the TPS as you...

Meh, no big deal. After all each time someone here admits to yanking emissions equipment off they're doing the same thing. You violated USC 49, Chapter 325, Section 32703 (2): "A person may not disconnect, reset, alter, or have disconnected, reset, or altered, an odometer of any motor vehicle...

Jeez, how dumb does someone have to be to admit commission of a federal offense on the internet.

Adjust the TPS as per the manual. I'm surprised the engine idled anywhere near right the way it was. A compression test would be nice. Do a piston soak while the plugs are out. After you adjust the TPS set ignition timing.

At least the cat is working. Working hard too. HC must be pretty bad engine-out if the tailpipe numbers are that high. Is that Vf of 2.4 volts at 2500 rpm with the jumper in or out? And if with the jumper in is it an average? Is compression OK? As I said before you have two problems. The CO...

It tells me you're likely barking up the wrong tree. Be sure you have a code 51 with the throttle cracked and no code when it's closed. Why are you screwing with the ISC valve so much anyway? From what I've read you don't have an idle speed problem. You have an idle quality problem. Different...

Yes of course. Not my intention to knock the product Aaron. Let me rephrase: You came up with an affordable solution to a problem that could be employed by the majority of a community who lack the know-how to do it better. That's it's not something everyone would use doesn't reflect badly on it...

Tis true. Try and find coarse pitched cut thread fasteners on aircraft or other aerospace applications. You won't. There's a reason for that ;)

If I ever do mine I'll helicoil to stock. No need though because I doubt I'll ever be taking it off again. The ones I did came out hard though, real hard. Had to use a pipe wrench on one. There are also ways around annealing of the head if that is indeed the cause of this problem. The upgrade...

If it is the CPS they'll be coked oil on the manifold under it. I cut a gasket in addition to the last new O ring put in. Zero problems since.
