Engine
Hi Im a newbee and I really need help. I have a 2004 ford freestar and I have been having problems with it for the past few years. I repaired the transmission last year and again having troubles with the shift. I changed the tps last week ran ok for a day or two and again the engine stall and when it reaches 40 mph the motor shuts off. This happened to my wife three time while driving my daughter to school. I have searched the forum and applied a couple of things but had no luck. I dont know what else to do. Your help will be greatly appreciated.

Thanks for your help hanky. I changed the fuel filter about 10 months ago. But I will change it again today when I get home from work. The engine shuts off at 40 mph while driving most of the time I turn it on while driving I shift to neutral.

Hi: My wife just got home from work and I was not able to change the fuel filter cause it was pouring cats and dogs but my wife tells me that the freestar didnt give her any troubles except for hard shifting on the trans. She drove at 55 mph, no problem.

hanky: I was able to change the fuel filter eventhough the vehicle ran very good for the last two days, but today I took about one hour and a half to pick up my wife at her work cause I had to drive at 5 mph because If i pressed the gas pedal the freestar would shut off. In park or neutral the freestars rpm are pretty steady but when put in drive the rpm get all crazy and the needle starts to go up and down. any help will be greatly apreciated.

Ok what Ive done and results.
1: changed the spark
2: changed wires
3: dismounted the cowl and mounted
4: took out pcm blew dry with air and mounted
5: replaced the coil pack
Results: Having the same problems. In park no problem, press gas pedal, no problem. In drive no problem, press gas pedal motor shuts off. I bought a OBD II code scanner and I get code 340 and 2198. If anyone have an idea as to what else I can try please let me know. Thanks in advance

I believe the code P0340 refers to a camshaft position sensor circuit malfunction.
" ' P2198 refers to stuck rich condition on bank 2 , sensor 1
If the vehicle has a v 6 engine , bank 2 is the fwd bank, sensor 1 is the o2 sensor in the fwd bank exhaust pipe before the converter.
The 2198 code could be the result of either excess fuel to the fwd bank or the cam sensor circuit not sending the correct firing sequence to the ign system.
If the problem is the cam sensor , there are times when the vehicle is started and the right sequence happens to be picked up the vehicle will run fine until shut down and restarted, if the right sequence is not indexed, engine does strange things.
