    Hi, Recently for no reason, the idle on my 88 tbi 350 went from a steady 900-1k to 1500-1600. It's been pretty chilly around here of late so I have not done alot of work to find the culprit. I did take some starter spray and it will stumble and almost dies while spraying around the TBI to intake gasket so I presume this is the cause,, anything else I should look for or do when I get the weather and time to replace the gasket?
    Thanks in advance,

    TBIS are famous for leaking at the base--->intake gasket.
