So I was about to go to work, turned the car on and it started and sounded perfect, but the check engine light came on...
So I turned her off and looked at it and started again, same thing.
It was idling perfect about 1500 or so, "warming up"...
So I was like, I will let it warm up, once it did the idle was sparatic, going from 800 to 1500 up and down...

So I drove my 99 neon to work... (arg, no power) so what do u guys think, Im gonna get it scanned by the obd II when I get home, but you guys have any thoughts of what it might be.

 

The ULTIMATE Check Engine Light Thread!, The MOST important info you can have!!

 

I think it might be a sign of catastrophic engine failure; we'll know more when you tell us the code.

 

(but start with your gas cap to make sure it's on properly)

 

LOL u guys are funny... but why and how would the gas cap be causing the weird idle...

 

have you installed anything recently?

 

nope, only thing i did was cut the speed sense wire under hte pass dash to let the top go up in motion (and no I didn't cut any other wire's and I doubled checked that already). And nothin was wrong after I did it and tested it on the road..

 

oops....i missed the idle part..

 

Mocky, wheres my badge Damnit!!!

 

OK guys its P1519.. which is like the idle air control circuit...
So what u think is bad..
