92 teg ls shiny intake, header w/full exhaust, 12lbs flywheel and 6 puck clutch... it all started when i replaces my thermostat and found a hose going to the IACV leaking.. I replaced it and now the car rshared_pm jumps form 2k to 800 to 2k to 800rshared_pm for a bit, then settles down.. sometimes it will not do it at all.. the throttle body gasket is okay.. anywhere else to look??
