I need some help 02 dash lights flicker like crazy after 2 or 3 times
it will start when it warms up I turn the car off I get reduce power.
turn switch on off then I get power.
I have check the tac it was loose the pcm has a lot of battery acid/corostion where it mounts to the frame what is the best way to clean its all around the bottom of pcm.
Id take out the PCM, carefully remove the board out if you think it might of penetrated the case and use a scotch brite pad to scrub clean it and around, do not damage the rubber gasket. when putting back together you could use a very light bead of blue sealant to maintain water repellant etc from getting in.
I did it with my truck PCM and have no issues what so ever
If you have any acid on the connector to the TAC or PCM you need to disconnect them and spray on some battery terminal cleaner and then rinse with water and let dry. You need to also clean the pins on the TAC and PCM. Be careful on these, I would spray a Q-Tip with cleaner and make sure they are cleaned and dried.
Don't do any of this until you disconnect the NEGATIVE battery cable first.
