Need Help! P0507
Hi all,
After replacing my thermostat I went to clear all existing codes but I received a P0507-(Idle Air Control System Higher Than Expected - Engine Speed too high). I've been chasing around what I believe is a vacuum leak but I have zero idea where its is coming from. The RPM generally stays at 1750 but will drop down close to idle then will almost bog down and stall out. While I was replacing the thermostat I replaced the intake manifold due to cracking and I also replaced the PCV hose that comes out the back of the valve cover. The vacuum pump and HPFP are brand new and I have data logged both and they seem to be working just fine. Any input would be greatly appreciated.
Thanks,
Tyler

*UPDATE*
After further investigation I found a few things.
1. PCV hose had a crack when replaced I saw a drop in a few hundred RPM but still had the same code after clearing
2. Fuel tank purge valve hose also had a crack replaced and still had a the code after clearing
3. Main connecting port to throttle body was split in half replaced throttle body, cleared codes haven't returned since
Car ran fine for a few days never took it out received another code P0303 so now im on the hunt to find out the cause for this one
Here is the new thread I started for this misfire: https://www.northamericanmotoring.co...oss-p0303.html
