    Anyway I need some help with this idle problem, The idle was fine before I started changing the Master cylinder. basically I took the CIS off the car and moved the lines over so I could get to the master cylinder better, well I sprayed the cis out with carb cleaner, and cleaned it up a bit put a new fuel filter on, and put new washers on the banjo fittings so I would have no leaks and then put it all back together, now I have brakes, but no idle. it revs fine, it drives nice and smooth, but if I let it idle, it dies right away.

    Any Ideas?

    Thanks in advance

    Vacuum leaks?

    I have a new intake boot, and I have looked around and haven't found any, going to have to start spraying some carb cleaner around I guess.

    I noticed on the throttle body where the idle screw goes, it sucked my finger into it, so I put it over it and it didn't help any.

    I took the all the cis lines off, and then used the same copper washers, its not leaking any fuel there, do you still think I should get new copper washers??

    I drove it around tonight, ran good, felt like it had a loss of power, but every light it would shut off so I had to keep my foot on the pedal a little.

    Have you checked/replaced the o-rings on the injectors? Have you checked the timing? Is there an idle screw in the TB? The o-rings go bad on that screw also.

    Injector o rings = have not, but I will
    Timing = haven't checked it yet
    going to take the throttle body off and check the screw and replace it.
