Wierd problem and cel

[Silverbolt_2003]

I am utterly confused with my car right now. First of all, the car is running great. about 20 min ago i drove it and it would feel like it would lose power for a split sec, then come back. kinda like a stutter. but that is not the problem. i would drive it, feels fine then when i come to a stop, in neutral, the CEL comes on and the car runs like utter poo. barely runs at all. I turn it off and start it back up. Runs fine like it had no problems. Come to a stop sign does it again. same thing, runs fine. i get to a stop light, does it again, so i say screw it im going home. I look over the car, find no loose connectors, nothing. I find a tee on one of the selenoid, on the firewall(red dashed lines) with a cap that isn't sealed off completely. Fix that, idle drops to about 800 and seems to run better. But before i did that, i reset the ecu via unplug the battery for 10 min. I cant seem to find any leads to what is wrong. the only thing i notice is the wires leading into the O2 sensor move around at the top. where the four wires go in and that little metal cap moves with it. i dont know what is wrong. please help. and sorry for the novel. thats the best description i can give.

thanks

Would it be too much to ask to get the code for your CEL pulled?

Exactly, let the ECU help by telling you what it thinks it wrong.

In case you don't know how. http://www.ecanfix.com/~mdhamilton/errorcodes.html

i will do that, im gonna get a voltmeter or rent a code meter and see. the only problem is that it only does this every once and a while.

No need to rent a code meter. You can put together a cheap 12v LED or 12v Piezo buzzer for less than $5. Since this problem is intermittant, the LED might be a better choice so you can leave it hooked up. When the ECU is fine it will flash out a heartbeat (on-off) and the buzzer would be really annoying. Pin 1 on the DLC would connect to the positive lead of the LED or buzzer. Pin 12 is ground. If you can't find a 12v LED (with an internal resistor) you can use a regular LED and a 560 ohm current limiting resistor. The 1/8" spade connectors like the ones used on speakers will fit on the DLC pins with a little tweeking. This is what most cheap datalogger cables use to connect to the DLC since the real connectors are hard to find.

ok i might do that, my dad has a voltmeter so i might use that.

Ok i finally was able to pull the code and it was 11. now i just need the O2 sensor. Where would the cheapest place online to get an O2 sensor?. Over at kragen, they want to charge like 75 bucks. I dont want to spend that much. much appreciated.
