i sold my 2001 sunfire about a year ago to a friend. the other day the car wouldint start. she said she turned the car off and then speedo and everything on the panal started going crazy and makeing this grinding sound. so she went to start the car and it was died it wouldint turn over it wouldint click it wouldint do anything. so we tryed to jump the car with a jump box it wouldint do anything. so we went and got the jeep and jumped it with that. after a few tries it started up. so we got the car to my house and it was fine. parked it and turned it off and a sec later i started it again and it started right up. but then yesterday i drove it for about a hour to the store get in the car to leave started it and it started then died again. so i started it again and it started up. whats going on with this car? its a 2001 sunfire with 100k on it. everything is stock on that car sept the battery its going a red top one in it thats about a year old. also it does have the RK sport CAI intakeing on it with the K&N filter the filters 2 years old and hasint really been cleaned.

Sounds like a bad battery, or possibly a bad alternator, i would take it down to Autozone and let them run a test on both of them and see what they come up with.

k thanks ill bring it down today. i took the air intake off it and just put the stock air box back on but i didnt put the bong in the bumper back in. will it be fine with just the air box?

I agree, get a battery/alt test somewhere that does it for free. A bad battery shouldn't do anything but fail to charge or fail to hold a charge well. An alternator shouldn't make the gauges "go crazy" unless the voltage regulator was going off/on.

If the battery and alternator seem to check out, check the wiring to the starter, alternator, etc. as well as all major grounds. Check for voltage, continuity of grounds, proper switching on/off where appropriate, loose connections, and shorts between hot/ground or hot/hot. Electrical problems can be tedious, but they're usually very logical.

The separator/bong will extend the life of your filter by letting larger stuff fall out the air stream, and it will also keep moisture out of the filter and intake stream the same way, but it's not necessary other than that... unless you plan on hitting some pretty deep puddles!

A word about oil bath filters.... K&N is just never a smart choice unless you simply don't care about premature engine wear. The proper way to increase flow is by keeping a material with good filtering properties and increase the surface area of the filter media. Bigger surface area = flow without compromise. A much better alternative to oiled filters, if you absolutely don't want to increase surface area, is Amsoil's EaA series. They are the best filtering media I've found, even better than cellulose media, and they have about the same flow as a K&N. They're also reusable and have a 100k mile guarantee. I'd never put a K&N on anything I cared about....
