everytime i stop at a red light...my rev stays at 1..then it suddenly drops to 0..where my car would turn off...then i would have to wait a couple of minutes to turn bak on..people are tellin me its my main relay..wat do you think? help me plz

ohyea i have a 94 ls

 

find another main relay and switch them out. if the problem goes away, then you need a relay.

 

i barely bought a new main relay..drove it around for 10 mins..doesnt turn off..but my idle is really low...sounds close to shuttin off..u think its my IACV?

 

HELP MEEE

 

 

whe does it do this? when its warm or just when ever?

 

mostly warm

 

IAC maybe, Fitv maybe, doesn't sound like the main relay considering you replaced it and the symptoms are still there.
