Auto Enginuity question
So my '03 has been going downhill in terms of starting, smoothness, efficiency over the past year...all in the subtle ways aside from cold temp starting. I've thought about getting the fuel system run through and diagnosed by a pro and doing as much as possible myself but I plan to have this truck for quite a few more years.
Is my money better invested in AE? Is there anything I wouldn't be able to test and diagnose under the hood that a dealer can? Thoughts appreciated...

I would test the fuel system first... It's absolutely critical for our trucks that the fuel is delivered at the proper pressure and that's one of the primary failures too.
That said, AE will give you some major diagnostics capabilities that will might grant you lots of friends (and possibly beer) from other FTE members local to you.

IMO AE will pay for itself after diagnosing/troubleshooting some issues. I was dead in the water and bought AE to get some info and once I had that my issue was resolved in minutes. I would have spent more money throwing parts at it or paying someone to run diagnostics. Well worth it, especially since you'll be keeping the truck awhile. That being said, it isn't an item that i use on a day to day basis but it's there if i need it.

Thanks for the input so far. I'm leaning toward getting AE for future benefit, but the one direct question I didn't include is this; With AE, are there any of tests I would want to perform on the fuel system that I would not be able to (for instance, will I be able to weed out individual injectors)? Obviously I will need the knowledge to perform the tests and between my OEM shop manual and the knowledge here I think I'm covered.
Hoping to start with reading FICM voltage in the next couple days for a start, just picked up new meter leads so I can do it all solo...working afternoons can be a bugger.

You can't read fuel pressure but you can do a cylinder contribution test do an injector buzz test. I haven't done it but you can turn individual injectors off plus turn fuel pump on/off along with many other sensors and components..i.e. turbo, lights, wiper motor, etc.

Thanks for the advice guys. Going to keep the fuel pump in the back of my head. I didn't get detailed on all my symptoms to stay more on topic. I'll be getting the AE Ford bundle next week. I suspect ficm or injectors and I think the added ability will help me tons down the road. I'm sure I'll be asking more in other threads soon...
