In short, the car is running very rich and the idle oscillates between 8 and 1000,the valve cover is leaking, aswell as the oilpan , i get the engine light/code for iginition coil 1 but it goes and comes with throttle manipulation. I assume the coil/wire is bad im also going turbo soon so i opted to convert to coil on plug. Whilst confronting this issue.
Along with the bad spark im certain the fact that i stripped the 2 intake manifold studs, may be contributing to a bit of a vaccuum leak? or is it not that bad? (The nut does lock it gets sort of tight then spins around)
So my question ultimately is would the stripped bolts on the intake manifold allow for air leaks? Does the leaky valve cover and oil pan contributed to vacuum leak? Does a code show up when the 02 sensor is bad or should i assume its bad since running rich? I have alll the parts ready to install even the studs (any idea how to replace these?)
