Just earlier today I rear-ended a person ( not smooth, I know) on a busy street. Other than some bent headlight covers and pushed in bumper, i thought the car was fine.No leaks and it drove just as smooth as always with no funny feelings all the way up the RPMs. Well anyway waiting at a light on the way home I notice something very strange with the idel. It was as smooth as always but about every 5 seconds it drops about 100 RPMs and the car vibrates a little. This happens for like a second and then it recovers. Then in 5 seconds it happens again. I checked the engine bay and i dont notice anything obviously wrong but im no mechanic. If you have an idea of what might be happening or have had this problem please help me.

Thanks- Josh

 

You probaly broke your blinker fluid resivor!!!!!!!!!

 

Old joke. Seriously make sure the relays in front nose are still connected and no wiring is stripped.

If the accident just pushed your nose nose & headlight covers in you probably havne't damaged the primary frame, just the body and nose subframes which can be bent / beaten back into shape.

 

do you a/c? It kinda sounds like your compressor engages and kicks down the rpms a bit, the rpms are supposed to compensate for that but like vaughnc said, you could have broken a relay or solenoid that controls that...

i dunno just an idea

 

Thanks for the replies. Turns out I needed a new battery. I baught one and the problem is gone. Now im trying to bend everything back into shape. Fun.

 

and you were worried about all this other ****......hahahah
