What do you think is wrong under the hood if 5SFE rpms go up when you turn on the high beams?


I kid you not. It really happens

WOW!!! You just blew my mind....

need more details...

when you are idling?

how much to the rpms go up?

if its when you are idling and its only like 100rpm or so, its normal...

alternator loading the engine?

Bingo. Its the idle up due to current draw.

this is at full stop. RPM goes from 750 up to sometimes over 1000.

Little extra for ya, ever since I had a dealer in Stockton replace my distributor coil in January, if I sit long enough (15 sec), RPM goes down to near 500-rough idle then goes back up. Before that repair, the car would sputter. I thought it was due to the possibility the dealer didn't replace the coil at TDC, but it goes away when the car's in neutral.

you're alternator is working overtime, something probably wrong somewhere in the charging system

 

[tater_tot]

you have any amps or anything extra being powered

simple test to see if the alternator is involved, unplug the alternator and try it. keep us posted..
