Throttle body question 700 1987

Hi folks,

Since last time I cleaned my (scary) throttle body, I didn't have the right cleaner, I took it off again this evening to clean the last 10 percent or so of coking off its innards using a aerosol can of the right stuff.

Looking at the TB against the sky, after cleaning, there is still a line at the top and bottom where light leaks through. This is less than a hair's width, though.

Is this OK?

Also, I think I got some gunk out of the TB vacuum holes. I never was able to get them clean, using a wire, the first time. I'll be interested to see how she runs tomorrow (60 highway miles first thing in the morn).

As I prepared to adjust the TPS, I found that it was within bounds already - so I left it.

Thanks,

Ari

    Should run better after the cleaning. May be too late but also remove and clean out the idle speed screw adjust plastic housing.

    There is supposed to be that daylight shine through around the butterfly.

    That's what you are shooting for by cleaning it.

    As long as it doesn't idle too high, a little light creeping through is OK.

    Trouble is when there's no light and the throttle plate rests up against the throttle housing.
