2004 Quest S hesitates to start after replacing radio

[dtownfb]

I replaced the radio in my 2004 Quest S with a refurbished stock unit. The battery was disconnected for about 3 hours. Radio works fine. When I go to start the van, it turns over and then dies like it's not getting fuel. It WILL stay running if you give it gas but it idles very low, approx. 500 rpm. I took it for a drive and it drove OK although I noticed when starting from a stop sign or traffic light, it took a bit more effort on the gas pedal to get it moving. My wife is having the same issue today.

Could disconnecting the battery or replacing the radio have done something?

I connected my code reader to check for codes and there were no codes in the ECM.

Thanks for any help.

Finally after 5 days the "Service Engine Soon" light came on. The code P0442 (Small Evap leak) was stored in the ECM. Can anyone help with diagnosing this code? The battery was disconnected for about 3 hours.

It turned out my gas cap wasn't on properly.

And that cause it to idle low!!! Wow, I didn't realize they could be that twitchy and sensitive.

BTW, where did you get the refurb radio from and how much?

I was surprised the gas cap caused the problem. But I guess you need the right pressure.

I got the radio off of Ebay. I paid $249 and got a $70 credit for sending my unit back. I can't remember the seller but if you do a search for Quest radio, you'll havea couple to choice. Mine came with a year warranty. With luck, I won't have the van by then.

The toughest part was gaining access to the radio. There are several places on the web that describes the process. Read them carefully and read them before you start. Lots of screws. Nothing too bad but tedious.
