so my 1994 camaro 3.4 l v6 auto washaving some idleing problems got it hooked up to a comp it said th EGR TPS and IAC were bad. so i replaced them still the same problem occured. so i checked for a vaccume leak by choking the intake and found the car was still running when choked. so i found the leak on the pcv air in tube that runs from the intake to the engine its sucking in alot of air causing the idle to run high. when i choke the pcv tube it runs fine how do i fix it

 

Replace the PCV (Positive Crankcase Ventilation) unit and give that vacuum hose a very close examination for other cracks or defects, too. When you change the Exhaust Gas Recyling Valve Body ...and the Throttle Position Sensor (TPS) AND the Idle Air Control (IAC) sensors at the same time...sometimes...it will takes a little time for the ECM/PCM to re-learn their inputs and bring things back into a nominal and comfortable idle... For much more information specific to your engine and yet another venue to add to your list of sites for research... Please give this place the once over...
