[Richieboy]

It's feels better more power could it be a ground problem or in my head 92 wrangler manual thanks guys.
Happy pattys day!!!

Shift light is for economy purposes where it will get better mileage. Comes on based on engine load and speedo and throttle position.

 

[Richieboy]

Thanks. But when the light is not on she feels like I have more power is it a rev limiter. Or a ground thing

 

[Jester32]

Shouldn't be either. PCM just switches the light on when the right conditions are met. If it's running in its economic peak. It won't make much power. If you accelerate hard does it pull smooth through out the rpms.

 

[Richieboy]

It's just pulls better when the light is off some times it comes on and other times it do not come on at all the rpms go up Easy

 

[Jester32]

That's strange. Is there a check engine light or anything on?

 

[Richieboy]

Climbs rite up. Just werid. Ok good nite.

If the light is off, you are operateing it correctly,when you give it more gas, it gives the engine more power and the light goes off,its not to hard to figure out.

My light has a mind of it's own comes on when I lugging at low RPMS

 

[Richieboy]

Maybe it in my head.
When the shift light is off or not working that day it just drives better
No breaking up. That's all some days its on some days it's off

The shift light comes on at low RPM's recommending you shift early for optimal fuel mileage. It will often not activate under hard acceleration.

I'd bet your intermittent poor running condition is in no way connected to the shift light coming on.

My shift light NEVER comes on at all... I wonder if it has to do with the fact that I removed the light bulb?

For real, I removed the light bulb because I got sick and tired of the computer telling me to shift at all the wrong moments...

DON'T shift by that light; pull the bulb or put black tape over it.

 

[Jester32]
