so when my car is warm and im driving and i come to a stop the rpm's come to a really low dip almost liek the car is about to stall out around 300 rpm's. Thats not the only problem when i turn on the lights the rpms die down a little and even when i use the power windows or sunroof the rpm's dip down a little... anybody know what it could be? i searched couldnt find anything

 

the lights thing could be a bad ground

 

could be your fuel filter
i had the same problems like you did, it was my tps, replaced it from a junk yard,
easy and simple fix

 

alternator?? or sumthin isn't right in your EVAP system

 

my battery and alternator were just replaced less then 300 miles ago

 

i may not have the belt tensioner adjusted correctly the tension on the belt wouldnt have anything to do with it?

 

to the fuel filter

I know when my Idle was having issues i had a code for a EVAP systems control valve or sumthing of that nature. anyways, after I changed mt PCV valve, it went away and everything set itself back to normal. my idle actually jumped up and down so i dunno. just giving ya some ideas...

 

talkin' bout that screw on the alt right? that's another possible cause, saw it on here somewhere

 

if your tensioner was off, your car would be squealing

 

well yea it did that for a while then i tightened that but just to where it didnt squeal... talk about the most annoying thing

 

especially in the morning
