hey guy on my 92 z71 350 tbi, it idles rough and sometimes dies. esspecially in drive. park is ok but still a little rough.I cleaned the tbi. Could it be an intake gasket? all help would be appreciated. i Also have an good sized exhaust leak could this cause it?

 

intake gasket good possibility...with the truck running spray carb cleaner along where the intake and heads mee up...if the idle changes you have a leak...also check and clean the IAC(idle air control), check for vacuum leaks, ensure egr valve isnt stuck and probly the TPS (throttle position sensor)
