Fuses for oxygen sensor look good. Just received New GM knock sensors, new 2000 vette bosch rear oxygen sensors, stock iac, and tps sensor. hoping that clears the codes out when I put them on this weekend so I can properly start the VE Maf tuning. My new problem is after I changed the intake gaskets and cleaned up underneath and installed a oil catch can I am getting a high idle i have been playing around with the throttle follower, throttle cracker, and base running idle air flow and it seems to help alot with the filter on the catch can but when I turn the A/C on it hangs really bad. I also removed the filter and plugged it but when I do that the engine idles where it should but what hold and and wants to stall. My question is should I plug the catch can or have the filter top and what do I need to change to or adjust to stop the idle from hanging especially with the A/C on? Here is my can catch set up. Does it look right?
