Rouge idle when cold

[rodolan]

I'm having the same problem. Rough idle like hitting on six until it warms up. I've just installed my ficm that I had reprogrammed.It was starting fine with other ficm. I'm on my first tank of fuel so I can't report on my mileage yet. any suggestions.. Thanks......

M truck is an 03 and what code are you referring to?

Never heard back from Bill. The PH FICM tune really improved the way the engine runs at operating temp. But, I have to plug it in every night regardless of the temperature so that it will start in the morning.
Anyone else have this problem with the PH FICM tune?

I'm having the same problem except I don't have to plug it in. It just runs like crap until it warms up. Geaux Saints.......

The code I was referring to was your strategy code like the VXCF4 etc. Its important you guys fill out your user profile including your name, which you have done, but neither of you list your stratgy code.

I'm not sure which program Bill installed in your trucks. As you know they had a really bad Holiday season and are trying to catch up, but I'm sure he address this when he get a minute.

I don't have any heat inductive strategy in my FICM programs, the trucks will miss a little when cold(0-30F) until they warm up. Which doesn’t bother me cause I let them warm up. They've always started like that, but I've never had the Heat Inductive FICM killing Ford Flashes on these one. The trucks I deal with at work do though.

Can each of you tell me how long the injectors buzz when you turn on the key but don't start the engine? And do the injectors buzz the same or do they ramp up the buzzing?

I've had the latest strategy done less than 6 mos. ago. The injector buzz seems to last a few seconds, usually about the same time the wait to start light goes off, If it wasn't raining I could go outside and check strategy, but like I said I has a fe-flash done about 6 mos. ago. The truck runs fine after it warms up just not so good when cold 45* or less. Don't really feel any difference in performance and I'm checking fuel mileage now, will keep you everyone posted, if that improves I can live with the rough cold running. Thanks....

I'm not sure which strategy I have. I get two codes from my scanner, the first is VXBC9N8 and the second is AKZ2AH17. The buzz last for less than a second and doesnt ramp up.
Hope this helps and thanks for the reply.

Your code is the VXBC9. I am sorry I cannot be of more help, this one is for Bill, and I know he is busy.

I was asking about how long the injectors buzz, because some of them keep buzzing after the WTS light goes out. The trucks that do that seem to start and run allot better if you wait and start them after the buzzing stops vs. the WTS light going out. A light grade of oil helps, like Rotella 10w30, Delo make a 10w30 now as well. I don't know if you’re running a 15w40 or not.

Also when you park the truck at night, cycle the key on and off a few times. By this I mean....With the truck off...turn the key on, let the injectors buzz, when they stop, turn the key off and then back on again let them buzz and so forth. Do this a few times. This should help to clear some of the oil out of the injectors, and from what I'm told help alleviate some of the stiction.

Give it a try while your waiting to hear back from Bill and please let me know if any of that helps.

I finally got tired of the hard start issue and took it to the Ford dealer. They reflashed the FICM for $100. The truck starts and runs fine now.
Oh well, expensive lesson learned.
