Well you could re-read my post on this subject......

that you think it might be fuel

i went and did that test it runs but once it go's to run like crap i cant baby the throttle to keep it running like when the maf is hooked up..

so to answer that yes it still does stall when the maf is unhooked..

 

[ThatShoGuy]

i was also wondering if the unhooked the ect would the car run in cold start or warm

 

[ThatShoGuy]

well i was just out side messing with it when i play with the ignition switch some times it will turn over and run right some times it wont...

were can i get this swtich from

 

[ThatShoGuy]

bring TTT

 

[ThatShoGuy]

well with the tps unpluged it dont seem to stall out.. but it does run like crap it dont know were to shift..

 

[ThatShoGuy]

can some one tell me or find me a wiring diagram of were the tps and maf sensors wiring is ran.. so i can go thru them and see if ther is any bad wires

like what pins on the pcm and the route they take to get there...

I am having the same problem with mine, as we speak. It first started when I would go from driving at cruise speeds to parking lot speeds. THe car would die when i let off the gas. And the problem has gotten worse over the last couple days. TO where it will bog down and die at highway speeds. But just like you say cycling the key brings it back to life as if every thing is good. This has been going on for a few days now, and it didn't throw a code untill i pulled into my driveway tonight.

Tomarrow I am borrowing a scan tool and hooking it up to monitor things as I drive. I suspect a temp sensor.

if you get code p1121

DH15 CONTINUOUS MEMORY DTC P1121: TP SENSOR AND MAF SENSOR RATIONALITY CHECK
Continuous Memory DTC P1121 indicates the TP sensor is inconsistent with the MAF sensor.

Note: Throttle Position Sensor A (TP-A) is the same as Throttle Position (TP) Sensor.

Possible causes:

Damaged TP sensor.
TP sensor not seated properly (almost completely detached from throttle body).
Air leak between MAF sensor and throttle body.
Attempt to start engine.

i got a new maf and new tps and its still doing it and it seems not to do it as bad as when its cold(the car) so im thinking coolant temp also but dont wanna waste anymore money on just throwing parts at it.. cuz so far i got about 200$ into parts and still no fix...

well i was doing some test with a volt meter on ohm's checking all the wires form sensor plugs to the pcm plug.. found that the wiring going from the mafs to the octain plug was open and none of the others going to the ect,tps were open so i wired a wire around to that hooked it all up took the car for like a 10mile ride no stalling haha this is great.. hope it last..

what is that octain plug for..
with the mafs not being hooked up and all the other sensor that go thru it being hooked up could this be my issue..

didnt fix anything still running like poo

first ride didnt act up 10-15min ride. 2nd ride about an hour didnt act up for the first 10min(about 20min after first ride) and then it just start to run worse and worse. then ses came on had it scaned and guess what said damn code p1121 mafs inconsistent with tps.. what gives if nothing is bad nothing is shorting out what is making the car think its not consistent ,

well you guys i think this is some of my issue

b4 this happen i moved front coils to the rear and rear coils to the front, and pretty much every since then the car ran like crap

so yesterday i was like wth im gonna move them back to the way there were..

so i did so drove it to work and home this morning.. didnt have one hickup

im thinking this is my prob....

http://www.v8sho.com/SHO/AllSHOandNoGo.htm

might not be the same coils or anything but

since swith the coils the car hasnt stalled yet.. and i put like ..... a good 20miles 10 to work 10 home from work.. and b4 that i swear it would have acted up sooner then that but were see im gonna keep driving it hoping its fixed but its not fixed cuz one of the coils has to be on its way of dieing i would think....... any input guys would be great

well im not 100% sure but i changed some coils out and my prob went away.....
so some how i must have had a coil putting its spark into the mafs and tps wiring.. some where down the line.. well so far so good car hasnt stalled once yet.

its been 4 days and like 100miles no probs with the stalling atleast....

Hi,
When Your Car Is Acting Up Instead Of Cycling The Key Try Unplugging The Maf First Then The Tps See If This Helps.
But I Would Tend To Agree With You That You Could Have A Bad Pcm, I Almost Sounds The Same As When The Rev Limiter Is Hit At 4grand.
Just For ***** And Giggles You May Have An Ignition Switch That Is Bad. Never Seen It On A Ford But I Have Seen Gm Act This Way.

i had exactly the same symptoms. With no check engine lights. After reading this thread about the number 8 coil I tried switching number 7 and 8.

Problem solved. SO i ended up buying 1 new coil pack for number 8 and the car has been driving great since.
