how would the iac be related to the oil pressure

[JBIROCZ]

well i thought the iac had something to do because its in the throttle body, so what is related to the oil pressure?

[nitemare3o5]

oil pump

sending unit

gauge

sorry for askin again, but where is the oil pump located nitemare? and also wheres the oil pressure switch? is the oil pressure swith the "gauge" that u mentioned?

either the guage is just reading wrong or the sender ofr the guage is bad, the pump is going out or the motor is worn out and bearing clearances are causing the low pressure issue. hopefully the first two are your culprit, because the other two require removing the engine, and most likely a rebuild.


go to autozone and buy a mechanical oil pressure guage and install it where the electronic sender is (on the back of the block right behind the intake beside the distributor.) if it reads the same, then youve got internal issues. takes about 30 minutes and about 15 bucks was what i paid for my cheap autozone mechanical guage
