Just "Old School" I guess, most likely have the protection built in by now. I often work on older cars/boats where it matters for sure. Habit not to take a chance...

Tx for helping out!

ok alt and batt tested and passed. mass flow sensor cleaned. fuel filter swapped. new batt cables installed. gonna flush coolant seeing as how its not been done or checked in 7 years since i have owned it. and am told that its possible that after driving as much as i did that day the temperature sensors could have been effected.

'To test the alt, start the car, and unhook the battery, if it keeps running, alt is fine.'

X2 sailor and ridiculous, you are running on residual magnetism there and means nothing, you have also removed the battery as the load and the alt can then go up to full no load volts which can be 70-100 volts. Good way to burn out your stuff, I've done it before. Even if not, simply running at idle with no alternator load at all is not proof it's working correctly at all. Do it with defroster and a/c on and every load you can find and watch it die then. Every alt and vehicle maker I know voids warranty as soon as that procedure is mentioned and even now. Alts are not mags. You may get away with it on some vehicles but depending on electrical it may well burn you, simply a dumb procedure and all training in car electrical still says so but with even greater force now.

I changed plenty of alts from people who said they did it and then things started going wrong after. No warranty either after they said it.................

If alts truly worked when battery disconnected you would have found perpetual power and be a billionaire.

Fuel filter?

Did you run an alternator voltage test using the Electronic Odometer trick?

Did you clean the MAF with MAF cleaner or electrical parts cleaner (same stuff)...? It's a $7 aerosol can, and it will last for a long time, and can be used on all vehicles with MAFs.

Have you seen about getting a compression tester and testing compression? You have an SPI engine, those are known to self-destruct by dropping a valve seat. That can "feel" like what you're experiencing if it broke up and is not causing damage inside the cylinder other than loss of compression. Compression testers are as easy to set up as changing spark plugs, and will cost about $12. You can rent one with a leak-down test kit.

Finally, what do your spark plug deposits look like? What is the gap? There's a lot of diagnosis that needs to be gone through to figure out what's going on here.

dont worry i took car down the road to get alt tested with machine. fyi car is running fine now......like nothing ever happened. this is the second time this has happened...both times it was a hot day and i was driving hundreds of miles. if it were the valve seat cover is it possible to only sometimes show problems? and yes i got a can of maf cleaner for that job.

Let's see............long drive, car acts up ...............kind like a bad valve cover and oil is seeping into the spark plug boots and fouling out a plug.

Eh, a loose valve cover typically just leaks oil on the engine. That could cause engine oil to leak down on your spark plugs and that might cause some missing if the oil is full of crud that conducts. Oil itself doesn't conduct, but oil with crud does.

Did you ever change your fuel filter? We have a how-to on that on this site- the fuel filter is in the same location regardless of engine for all Focis 00-07, and the instructions are the same. I do recommend unplugging the fuel cut-off switch instead of removing the fuel pump fuse because that leaves the injectors on, and fuel will slowly flow through the injectors at low pressure which causes lean burn and possible detonation when you try to start the car to relieve fuel pressure. Some cars will just sit there and chug and pop after fuel pressure is relieved- especially if pointed downhill.

I think the problem is most likely in the MAF. Your conditions seem like MAF issues, but it could be a number of things- for example, a small vacuum leak might not give indications under most circumstances, but in extreme heat it could cause lean issues that would be similar to what you're experiencing.

On the cheap: remove and clean the MAF, check the PCV and it's line, remove spark plugs: check gap, wire brush or knife scrape clean, re-install. Definitely get that fuel filter, it's a $9 part, you can change it with the emergency jack if you're careful and make sure it's secure before climbing under the car. Don't get gas in your eyes, and don't remove the white clips from the line- press on the white clip until it clicks and then wiggle the line to remove. There is one white clip you can only see the back of, follow that line for another 6" away from the filter, and you'll see an easy to reach clip. Remove that small section of line with the filter and bracket. You'll figure out how to remove that little piece of line when you get it out from under the car.
