 Subject: 3.9 Stops Pulling at throttle position
IP: Logged
Message:
Well,
I'm trying to figure out where my problem is.
When I press the gas, I can feel the torque, but if i get the throttle to a certain point or more, it dosen't pull anymore. I notice it more below 3 grand.
Mods:
V8 TB (think it is 48mm)
JBA Headers
1.7rr
FM 40 series
any help would be great!

Throttle Position Sensor might be bad. Easy to check voltage on it across it's range, and cheap fix if that is it.

I had my cat checked, it looked good.
I will check the voltage..any other ideas? Could it be related to air flow? Too much...to little?

The V8 body on some trucks will show a loss in
volicity and lose low end
All trucks react diff you may have one of them
The V8 bodies have 50mm plates and a 48mm torque
step
Most will have mid and top gains with the low end
remaining the same or show a loss
The fastman or F&B show gains across the entire
rpm range starting right off idle, the V8 body
is just a cheap way to go for those who can not
afford the $250 fastman or $380 F&B
Check the TPS key on engine off should be between
.3 to .7 go up as throttle opens and always return
to low volts. and not over 4.8 on the top
center wire + and ground
If your reading low just remove the sensor hook
the bushings with a drill bit alow them to spin
they will heat up and push right out
Than use 2 small washers and reinstall and turn
all the way counter clockwise
.7 .75 is what to shoot for and will help throttle
response
Oh what a life I lead pizza again have to go LOL
These people know I love the stuff and stop over
all the time with pizza when they want something
done on there trucks or cars
