Hi everyone,
For some reason, my idle drops down to about 300 rpm's when I am in drive and stopped at a light. I had this problem before when I had a bad alternator, but I changed my alternator with an OEM alternator rebuilt.
I checked the factory service manual and it states that when in nuetral, the idle should be at 720 +- 50 rpms. For my car, when in nuetral it hovers between 450 and 500. Is this too low?
And is my idle too low when I am in drive/stopped at a light? When it drops, my car gets a little rough (it seems like the car is fighting to not let the idle drop so low).
Also, I have noticed that my headlights lights dim if I leave them on and shut the car off. I don't know if this is normal to save battey consumption or if this is a power problem.
I did notice however that my alternator is putting out about 13.5 volts. The FSM states that that is fine as long as the voltage does not get higher than 15.0 volts.
Help if you can. I am thinking it could be something air related, but afte the headligts dimmed a little after the car was turned off, I am now thinking that it could be something power related.
Thanks everyone,
Geoff.
