No codes yet ? no fuel pressure or volume readings yet ? Recent filter replacement ? it is recommended the fuel filter be checked and or replaced every 15K and definitely replaced at 30K. No evidence about spark plug condition noted. it is over 10 years old and we dont know the mileage or the service history. The general condition of the vehicle can also be an indicator to a technician. Daily driver?


Replace your plugs and coil packs. Most of the time this problem is due to a misfire in one or more of the coil packs. This causes the EGR to malfunction as well.......

The fuel filter is new daily driven approx 100 clicks per day only starts choking after going about approx 12 clicks when it is warmed up if I drove around town all day I wouldn't even know it had a problem have about 194000 clicks on it.some1 said maybe throttle sensor?????


Brand new k & n air filter no lights no codes can go 140 kph no problem then after 10 to 15 clicks starts chokeing


Could it also be described as bucking and hitching ? A tiny chunk of exhaust debris can keep the egr from seating at the pintle. Throwing several hundred dollars american at it is not recommended yet. Inspect and clean the valve and passage first and return with the test results you can muster, please. There is a driveability inconvenience so far but no evidence of part failure, not even a code set.


I hear you saying it is at freeway speed, and fully warm. a test to verify cheaply is coolant temp with a corrected thermometer. when it is acting up, pull off and dip the thermometer in the coolant, looking for 192 deg F or higher. motorcraft thermostat can act up by sticking open and staying open too far. weak fuel pressure and pluggy injectors or regulator acting up begs the tests be run to isolate. A good piece of advice is a tech taking a road test to help define symptom in automotive terms. (Choking? That's like blocked airflow. or over fueling, smells gassy, and smokes black smoke ?) We need to determine the best description for the symptom.


Yes bucking and hitching sounds right but not sure if mine even has egrv


Egr can be verified quick by reading next to cafe decal. (or tune up spec sticker) Attached vacuum routing diagram will depict your system. Green always routes to EGR

TPS tests can be made with a dvom simply enough. but kicking and bucking on takeoff is more common symptom for a TPS that bucks, jerks, whatever. the throttle opening at freeway is a different action and the inert gasses leaking in the egr is mor likely because you are at cruise. Back to having a tech drive with and saying... it feels like ??? to me.


Save your money on the fuel additives, anything that actually helps would melt your fuel pump. If your dealer does not want to manage a symptom with an additive ? It is because it does not help to cover up the concern chemically. The chemicals that actually help are not available to the public because of what they do. Isolating the injectors would be necessary, and depositless injectors were used starting in 92


We have been exchanging generic ideas so far, you have people launching multi hundred dollar blips and blurts, I reread the list of ideas and cosidered a sec to get a mental pic... you havent even said what engine was in there. I was thinking 4.0L but 3.0L and 2.3L were, historically, also used. Service bulletins get written for fixes that help people with updated parts and procedures. They can be found by symptom, and usually come at it listing several. Your service advisor at your Ford dealer can run your VIN and offer service definition codes used by OASIS or the latest equivalent Ford information system. He can also offer you the gist of the bulletin after discussing it for application and tell you things even the parts department may not know. Yours being this age, I would hope the numbers had trickled down by now, but, hey, when I worked there you had to make your own parts out of dirt, so feel free to ask the new kids.
