I recently removed my intake manifold and throttle body to replace the heater feed and return hoses that lie below. All new intake gaskets and all seemed well. I did some front brake and shock replacement so I did have it up on a jack. After 2 days of running fine my wife had no luck starting her precious cat. When I got home it started right up but stalled after about 10 seconds and after a couple attempts I decided to pull codes. This is what I got... PO300 random multiple... fuel sys stat B1 B2... CL not ready...
S.T fuel trim B1 -0.00%... L.T. fuel trim B1 -0.00%... cyl misfire detected...
PO303... PO306... PO307...PO332Knock sensor... low input Bank1...PO332 Knock sensor 2 circuit... low input Bank2
Any thoughts my Jaguar friends? Not worried yet on the Big Island

 

I would look for a coolant leak. The knock sensor wiring just doesn't like water. With multiple misfires could be a false flag caused by the knock sensors. If you have a compressor blow out the valley and watch for water. If not do a cooling system pressure test.
There is a small hose going to the throttle body shaped as an elbow. When I did my tensioners that is the one that made the knock sensors crazy with a small leak.

 

The coolant leak I had seems to have been addressed and I've continued to retrace my steps in search of a possible culprit but having had the manifold removed the valley was carefully cleaned and there are no signs of an additional leak. Mahalo for your thoughts
