I had the reflash done in october and haven't had the hard start or stumble at cruise sense. About the oil filters.... it has NOTHING to do with hard starts or stumbling. The check valve is less important with the duratech engines because the filter is verticle. The check valve keeps the oil from draining from the oil fliter, causing lifter noise in hydrolic lifter cars at start up. The big issue with fram filters is the amount of filtering media. The FL-1 ford has 390 sq inches of media, the fram PH-1 has 190 sq inches. I wouldn't touch one.

That's funny--I was under the hood just last night and noticed that the noise suppressor grounding wire was broken. Looks like it snapped clean off at the base. Kinda makes me wonder if this is a common problem.

When I took mine in, the Idle Air Control valve was replaced. The computer was been reprogramed, but the intermitent condition still exists. Is the Idle Speed Control Valve (noted as what was replaced for ZX4ST_DFW) the same thing as the Idle Air control Valve? If not could someone clarify the difference?

Just got mine taken care of today. The did the reflash required by the TSB. No issues with it so far tonight, but time will tell if that took care of things or not. I'll let ppl know if it didn't.

I had the same hard starting problem and had the update downloaded last month. This almost cured the problem. It still has long start times after short trips, but it is better. It dose not seem as susceptible and I do not have to crank it as long when it dose trip. I will check the grounding wire that others have found. I also am going to check the plugs. The stumble at cruise was not just at highway speed but around 2800 rpm in any gear if held at that rpm for any amount of time. (Most noticeable in 2nd gear in a parking lot) This has gone away almost completely. Before I also noticed that the car had almost no engine braking for 2-3 seconds after lifting, and now it is almost immediate

8 days later, so far so good. No stumbles, no hard starts, things seem to be good.

Ok,

I had the same problem...hard starting on my 05 ZX3, I took it in and had the re-flash done. Did it again the next day, went back. I was told that because of the cold weather, it takes longer for the fuel pump to power up. So I was told turn the key to "ON" wait a second or two then crank it. I do that all the time now and have absolutely no problems starting it.

same here. i wasn't told to do so. but realized that if i did that i didn't have a problem. then i remembered an older gentleman i worked with a few years ago. he told me to do this and also not to start driving until the revs have settled after the start.
