idle problem in gear /92 auto
i still have the idle problem: the car idles a little bit rough in N or P. when i shift in D the idle goes down to 300-400 rpm an it`s a noticeable rough idle.
it occurs after i changed the oil pressure switch. the oil pressure sender is still dead, buit not ecm connected an just for the gauge.
i checked the iac already (new). i disconnected the vacuum lines to reach the oil p. switch an put all together in the right place.
i seems the ecm is trying to relearn the idling.
i had the problem already but i forgot how i solved it ( i´m already 35). maybe it has somnething to do with iac. but i didn´t touch it.
maybe the diconnected vacuum lines were the problem, i´m not sure if there is always vacuum in the system until you disconnect a line. maybe after disconnection the ecm didn´t know what to do ?
thanks i a

p.s. i noticed a code also but i´m not sure what it means: it a "h 74" code when i jumper the aldl pin a and g.
