Need Help A.s.a.p.!!!!!!!!!!!!!! Hey guys...
I'll try and make this short...
Just got finished washing the car. I was extremely careful when washing it. Using no pressure, brush for cleaning, and just rinsing... also used an air line to blow away the water afterwards...
I just started up the car, and the volt meter in my odometer is fluxuating between 13-16 volts... the car is making a pulsating electrical noise and I can see my radio light pulsating along with it... the voltage is higher than normal but not quite hitting the red on my guage...
Also, in case this is relevant... The new engine was just put in about 4 days ago...

we've been having some issues getting the car to hold Idle for a while now, and it's fine when warmed up, but on cold starts it wants to die... don't know if the two are linked or not...
i'm running to autozone in it right now in hopes of things going to normal maybe after everything has dried up, but when i get back i'm hoping to see some ideas!?!?!
Thanks guys!!!!
Forgot to mention.....security light also came on??????
Thanks again!!!

as far as the pulsating of the lights thats a dead sign of a bad altinator. lights are pulsating because the car is using more power than the altinator is putting out, in some cases you could have a bad ground in the electrical system as well but usually its the altinator. as far as the car not wanting to idle when its cold that could be multible things

Check alt out put at the R terminal before buying a new one. Just use a volt meter with pos. on the big red wire on the alt and gound wire to the frame and should see 12-14volts.

a bad alt can actually over charge, altinators are made to adjust how much they charge, if your runnin lets say on a hot night with your ac on and headlights then the car pulls more juice rather than in the day time when your not pulling as much juice so the alt will adj its self so that it can keep the batt. charged. i had a bad alt on my truck and it over and under charged before it when out. but it may not be that it could be a ground, check the alt ground, if the connections are dirty it may not have a good connection. it would probley be best to start with the batt connections and see if there dirty, and if you want to check the alt go to auto zone they do it for free

Regarless of weather or not it's a ground problem, I would still clean your under hood grounds because they are known to cause all sorts of strange problems. Can't hurt anything to clean them anyway.
