I have a 1995 sc300 stock 2jzge. OBD1 obviously. I have gotten codes 14, 42, and 47. But to my understanding, code 47 is the main thing to worry about here.

Here's the issue.
I have an inconsistent breakup/stutter on the car. It will not happen at all times during driving the car, only seems to happen when I accelerate/decelerate instead of keeping a steady speed. Now, here's the symptoms:

While on the gas, and accelerating, the car will out of nowhere lose gas, like if I took my foot straight off the pedal extremely fast. Now mind you, my foot is still on the gas pedal and the car will act like it's idling(Mind you I'm also 5-speed so it will start to decelerate because I'm still in gear). I have to re-apply the gas in order to get it going again.

And apart from that problem, another problem I'll have is that the car will seem to stutter randomly. Like what I just described above, but at a very fast speed it will re-apply the gas/acceleration and will jerk the whole car.

What I've tried to do to fix this:
I have replaced the TPS, Igniter(twice), Ignition coil, cleaned out my whole throttle body and replaced the air filter.

Now what I have to ask is, in the diagnostic for OBD1 I see there are two TP sensor codes. One is SUB tp sensor(code 47) and the other is TP sensor signal(Code 41). What is the difference?? What is the approach to fixing a "Sub" tp sensor code?

 

If you can wait till tomorrow morning i'll have the fix for you OR atleast give you something to work with. I don't mess with 400 alot so i have i can tell you off the top of head sorry.

 

It's a SC300* not a sc400...??

Any info you can give me will be a lot of help guys.

 

Here you go!

 

Thank you so much.. I gave the reference to my shop it's very useful. Does anyone else have any suggestions?
