    Hi. I have a 1995 Firebird Formula Convertible - Am in search of obsolete p/n 25147187 the air cleaner's rear intake duct tube hose. Found a few on ebay for over $150 - have called over 25 junkyards in DE and MD with no luck. Can you point me in a reasonably priced direction? If not, what's your take on switching to cold air intake system? What else needs to be changed if I do that? Thank you, Claudette

    Map reading would be around 3 to 4 volts.

    Maf on my scanner doesn't read the voltage. And I can't remember what an normal idle reading should be.

    But don't lose hope. Join the forum and ask the maf question. I'm sure 1 of the members will remember the correct idle reading.

    Hey man,

    You always come up big for me - thank you so much.

    I'm straight retarded when it comes to wiring. When you say put 12V to connector - would I need to run wiring from the positive battery terminal to the back of the car?

    Go to in component view section it shows egr components. As long as you keep all components and hook ups, egr will work. That includes the one pipe that goes from exhaust manifold to back of intake manifold.

    And since your a member, you can use the regular private message. Unless there's a minimum post count to use it that I'm not aware of.

    Reasons to change fuel pressure regulator. (1) pressure is low but rises to about 43 psi when regulator vacuum hosed removed & plugged. (2) pressure drops rapidly when you shut car off. And you have eliminated fuel pump, lines, leaking fuel injectors as the problem. (3) you remove vacuum hose from regulator and gas pours out, or you smell gas in vacuum line.

    And you can post in the member private message, as you are a member.

    To ililt1 if your a registered member you can use regular private messages.

    If your laptop went into sleep mode while programing you could have damaged your pcm. So even though lt1's rarely have pcm problems, you could have that.

    Low resolution wire is red/black and high res wire is purple/white. If your scope is a dual trace scope you can do both signals at once. If you have an old single channel scope like I have, you will have to do one signal at a time.

    With engine cranking and scope leads hooked up, you will be able to see low & high res signals as opti sends them out.
