this should be in the 96-98 (Mod, Please move this)
not telling how long the car has gone unserviced first thing you should do is go ahead change the oil, tranny fluid, spark plugs, wires, belt, and make sure the timing is good... after that clean the MAF, TB, check the IAT and that is a good start.. when buying any vehicle that is 10 years old + the initial service is a good place to start

since you're really new i would start with cleaning the Mass Air Flow Sensor. It located on the intake plumbing on teh passenger side of teh engine bay. Its metal and you have to use a special cleaner on it (mass air flow cleaner, $5 from any part store)
use the same cleaner to clean the intake air temperature sensor (its a small plug in the upper part of the intake tube on the passenger side)
buy a can of throttle body cleaner (also about $5.00 from any parts store) and clean the throttle body opening, but not past the butterfly flap. The throttle body is the large, square shaped metal part on the very top of the motor that the intake plumbing goes into.
replace all your spark plugs. I suggest getting copper plugs. whatever ford says is stock...
i suggest cleaning your battery terminals with a backing soda/water mix then applying petrolium jelly to the terminals (after you dry them with a rag) and placing on new felt washers.
I suggest changing your oil and filter.
I suggest replacing your air filter. (paper will work fine temporaroly.)
i suggets chaning your fuel filter ( located above the gas tank, two hoses pop off, new filter in, 2 hoses pop on, new c-clips)
i suggest running preium gas with sea foam ($10 from auto parts store) in it for a single tank of gas.
i suggest making sure exhaust gas is getting out of both exhaust tips... a catalytic converter could be clogged.
I suggest running a compression test on each cyliner (buy a gauge at any auto parts store)
i suggest changing your tranny fluid. bottom plug drains (passenger side, next to front catalitic converter) top plug fills (above bottom plug)
i suggest adjusting your clutch (put the car in first gear, turn off the motor and pull on the clutch petal (toward you) like tehre is no tomorrow, then slowly press the petal back in.)
i suggest changing your belt ($15 from auto part store) push tensionr down (toward drivers side of the car) and pull the belt off the alternator... replace belt in same pattern that it is currently on there.
i think tis an air problem, or a fuel problem. this will help rule out many of the issues that it could be. Im also thinking it could be a slipping clutch.
that should be a good start for ya....

+1 i'd start with the list above... that way you know when your oil and such was changed out and you can be sure that those are not causing an of the issues. it is possible that your throttle body is getting stuck or not opening all the way, but i'm with Chris, i'd start with those suggestions and then after you've done that let us know if it's changed; fixed; still the same

I recently had the very same problem with my car and it turned out being a bad fuel pump. It had enough pressure but it did not put out enough volume to run the car at high RpMS. Replaced the pump and I have not had a problem since.

yea, at least once a week one of my posts gets relocated to the right section... the way i see it is that moving my posts to the proper area is the only reason we keep Paul and Matt around. LOL!

you should get a svt focus pump and just put it in there anyways, it will be a good start for your fuel system mods even later down the road, and its a direct swap from what i hear.
sorry.... updates.. :wave:...cleaned both intake sensors, did the battery terminal clean, got the oil and filter replaced/ and trans fluid. new plugs/wires. i dont have the stock air filter box only the k&n cone i herd you could just rinse them and be good.. both tail pipes are emmitting exaust evenly....hmm have not replaced fuel filter or pump....ran out of money :laughing5: but so far no changes still revs up and then almost sounds loke bogging at 4k at w.o.t i dont think its the clutch chris because it happens even with the clutch pressed in and if the trans is in neutral....fuel sounds right tho...idk.... i should be getting paid wed....question... i have a 95 ford t-bird v-8 and i just replaced the fuel filter and plugs and wires i was wondering if those or any parts are interchangable???? thanks again guys ccasion14:
ccasion14:yes sea foam is ok to run in your car, although i'm pretty sure it wont help your problem any. i'd go ahead and replace the fuel pump and see if that helps out.. it could be clogged or numerous things. and changing them out with like an svt pump is easier than most people thing.. all you have to do is change the actual pump
