I’m searching for leaks in my intake to hopefully solve a rough idle. At the moment I can only find a very small air leak at the throttle body shaft and one at an injector o-ring.
The symptom I have is when I start the car cold the idle will go right below 2000rpm for about 10 secs and then drop below 1000rpm and then I’ll see the wideband go from 15 up to 18 to - - - and the car will idle really rough with small “pops” in the exhaust and will want to stall. My electric fuel pressure gauges shows about 37#. I checked timing and Its at 10d.
Could theses small leaks create this lean condition at idle?
