Got my new hose today, i cleaned and re-installed the IAC Valve, i made sure to bleed the cooling system, I was ready with my plan to find the cause of the rough idle. I was going to pinch off the PVC hose, i was then going to pinch the fuel return line hoping to increase pressure, I was ready with my brake cleaner and fire extinguisher to look for any vacuum leaks.
To my surprise when i started the car, it went straight to high idle (Cold in Pittsburgh), upon coming up to temperature the idle dropped. As of now this is the best this car has ever idle since I’ve owned it. I have driven it about 5 miles so far.
Thanks
