Looking for a bit of help.
Been chasing a negative fuel trim issue, sometimes near -18 on both banks.
Fuel pressure is good. 58
FPR is functioning and new
Injector pulse test 60-30psi, all the same, and new style bosch not rochester, I changed them myself.
Lower intake manifold gasket is leaking, at least externally.
No combustion gasses present in coolant
No coolant known in oil
Question is:
If coolant is getting into the intake, can this cause the O2 sensor to read rich and call for -15 % LTFT?
I did notice a leak in the exhaust manifold that was "bubbly"
Any help is appreciated
