'99 V10 missing, 1409 code set, EGR?
I just rebuilt a smashed '99 F350 V10 with 122K miles. It stumbles a bit at idle. When you give it some gas, it runs pretty rough until the RPMS come up, and then it smooths out. It does this at any road speed. I am getting a code of 1409 ( EGR Vacuum Regulator Solenoid Circuit Malfunction ) consistently. At one point I also got a code 0300 (Multiple cylinder misfire), but I only got that one once.
Could the EGR Vacuum Regulator Solenoid be causing this misfire? Or is this more likely a coil gone bad as I've seen is so many other posts? If it might be the solenoid, can anyone describe what it looks like, and where it's located on the engine?
Thanks iin advance,
Keen

How long was it out in the weather with the hood open like that?
It could have let alot of rainwater into those coils (or COPs - Coil Over Plugs). They are located under the fuel rail, beside the injectors. About 1 1/4" diameter. If water sits too long on top of the head it can migrate into the plug cavity. That could cause major misfire.
But, if the EGR was bad it could make it run rough also.
I would bet the coils are either corroded allowing the engine to misfire or they are toast.
Also the MAF sensor could be damaged. Have you replaced it? It looks like you had to replace many, many things in order to get that wreck going...
BTW - What exactly is the "real steal" bargain, if you don't mind me asking?

I don't think that rainwater was a problem. The hood was smashed in, but it was still covering the engine. Possibly the two front coils might have had water blown on them. I'm taking it to Ford tomorrow for a driveability test to see which coils are misfiring.
As for the EGR regulator solenoid, I replaced that today. It was not the problem. I still get rough running at low RPMs. The 1409 code is gone, however.
I think the MAF sensor is OK. It didn't look damaged, and I'm not getting a code.
A steal was $3700. I put about $900 into parts and paint. So I got an OK '99 F350 for about $4600 plus about 30 hours labor. May not be a steal for everybody, but I feel like I did pretty well on it.
Of course, I still need to find out why it's running rough, plus I now see that 3 out of the 4 ball joints are shot. I hear that is a really fun job!
Thanks for the response,
