Somebody help me with my car!!!! calling all smart people

[mattfurlani]

I have two problems, I need the expert suggestions of a professional engine diagnoser. if you are a mochanic or a parts replacer or someone who has worked very little on supras please don't waste my time. i have very little money and can't be spending any more than needed on this car.

1. air will not come out of brake systems. Have changed master cylinder which was pre bench bled before installation. new calipers and new hoses. new pads as well. rotors are fine (not important maybe?). I'VE bled it more times then there are hours in a day and still has rediculously spongy feel. no visible leaks or liquid coming out. front left caliper makes clicking noise when brakes are engaged. TOtally clueless. HELP!

2. engine voilently idles. it is a raising and dropping between 2000 and 2600 and will not go down to 800. checked tps sensor, idle screw, vacuum lines. EGR functions, EGRVM works. dash pot works. It is missing the Charcoal canister and BVSV from thermostat but lines to those are plugged. they may not be sufficiently plugged. We've secluded it to a air or fuel intake unaccounted for after the computer has recontrolled the condition. MAy this have to do with the O2 sensor? again with the cluelessness.


Also if anyone knows of the location of the PCV on this car i'd greatly appreciate it.
