RE: 1995 Tracker bog issue
it is sad no OBD2,
to find out if all sensors are working in few minutes.
all we have is checking them 1 by 1, for correct readings with a meter.

the ECU has what is called a conformal coating, this protects it form say bad weather and at dew point an like bottle of cold beer gets damp
it does not protect from submerged ECU.
this is pure, and has no water in it nor any oils of any type .
it will turn the conformal wax like coating frosty but is no harm that, just dont park the PCB in the ECU submerged in any solvent cleaners. spray on then blow off
blasting it on is good thing to bet all salt deposits and silt.

ECU looks brand new, no corrossion, no dirt etc inside, cleaned anyway but no change.
havent been able to remove the o2 sensor yet but checks out with meter and engine throws a code when disconnected but plan on removing it.
also it is now blowing alot of carbon and some smoke out of exhaust, leaves black spots on ground from exhaust but no oil.
