4k shutoff 2

first off, sorry for the other thread getting "stupid", i guess i have a freak of a t-bird or something.

but anyways, i still need help figuring it out.

my car basically shuts off at 4k rpms, no matter what gear, no matter what speed. every sensor on the engine has been replaced, it now has 02 sensors in it.

the previos owner installed an HO upper intake, stock stang headers, and 19# injectors. he thought he needed the bigger injectors for the extra airflow. could the injectors be what is causeing this?

it's been narrowed down to either the injectors or a computer problem.

Why do you need help if you already know?


Swap the f*cking injectors and eec and be done with it already.
Oh yeah, change the so cam to an HO while you're at it.

hey i got an idea! i'll be the referee..  you and your competitor can go have dinner and leave the cars with me...  if you find me crawling out from under the car*... have fun while you drive it.. be careful though you'll most likely have tranny fluid all over the rear tires :D

Yeah, my 351 will dog you, have fun being limited to 110mph.  This isn't a g contest, you're full of  and we all know it...no question, no arguement necessary.  So get off it and grow up.  Play with the injectors, see what happens...if no go, swap the ECU and see what happens.

My EGR was all clogged up and the control solenoid was bad, caused a similar issue.

my brother and i have been researching this all night and found a couple of websites that say 88 cougars run 125. we have almost come to the conclusion that these cars were never tested and that the 110 limit claim was put into place by Ford for insurance purposes. these cars will run over 110 if you have the testicular fortitude to do it.

I will say this...

One night after work, I ran my white '88 Bird up to 127 coming down an on-ramp onto a 4 lane.

The speedo had the W2 mod, and it was a 3.8 car....as far as actually going that fast...who's to say.

Do yourself a favor...grab some E7's, an HO eec and cam, and get to putting them in. Take pics.
that is all.
