it could be a bad or stuck injector (s)... I mean, it's kinda hard to gather alot of info from a video. I am no mechanic, but I have screwed around with GM and Ford engines and have had problems with bad injectors and it sounded like that...but it could be something else

if it's not that, I would really consider taking it to a Ford dealership or trying to find someone who is a Ford mechanic or see if any of your friends know one. The reason I suggest that is because it seems as though there aren't any real good auto shops near you where you can take a vehicle and get it fixed right. It would make more sense in the long run to maybe pay a thousand dollars or so to get it fixed rather than throw money at it ya know..

If you don't have the means to pay for that, I would try to find someone who has one of those diag programs to see whats up with it

Can you explain the process of having your injectors cleaned, and who advised you to pursue such a dangerous course of action?

On that note, let me just say I have completely no faith in any of your fuel injectors, and would suggest that since they have been cleaned, its probably a good idea to to replace all of them.

Leave the injectors dirty, don't let anyone clean your injectors. They are probably sticking.

Best advice, get the car hooked up to a diagnostic tool or scanner and see what kind of codes come up. IIRC, You can also do this yourself with a voltmeter or the cheap code reader with the flashing red LED light. (Think I still have mine buried somewhere... ) I'd also throw out the possibility of a bad 02 sensor or maybe a faulty fuel pressure regulator if you want to "throw parts at the problem" - but still, IMO better to get it checked for diagnostic trouble codes at a competent repair shop.

Was it ok before you had the injectors cleaned??? If it was then one or more has gone bad... Cleaning old injectors like MSP said doesn't work very well at all. How old are they? I replaced all of mine and it runs like a new car again! My 87GT was running rough adn would actually backfire a bit, changed wires, plugs etc and nothing, finally took out one of my injectors and it fell apart in my hands. Make sure that the passages are clean as well..
