Touchy Gas Pedal

Is there any easy way to make the gas pedal tougher to push down? I am new to offroading and jeeps. I find it really hard to keep constant throttle when on rough rocky terrain. I find my foot bouncing off the gas pedal causing the jeep to buck around sometimes.... Mostly in 4wd low. Is this something that I just have to get more control over with practice? Or is there something I can mechanically do? Thanks!

Yes, there is a simple solution: add a throttle return spring. My 2005 TJL also came without one as well. This was the first annoyance to be fixed when I took delivery. Another was to add a 1" spacer underneath the seat bracket to lift the backside up; otherwise, I'd still be staring at the roof.

I drilled a small hole in the black, upper bracket to keep the spring coil from binding, and as you can see, the throttle body lever is already set up for a spring. I had to experiment a bit to find just the right spring length and tension.

For more control, a thumb throttle attachment will increase idle speed for more control when off-roading. Not sure which you're after, but both solutions are well-documented.

It would be nice if DC would kindly allow Jeeps to set the cruise as low as 1 mph!

I am not sure if anything can be done for the gas pedal, but if your jeep is a manual, you can get a thumb throttle. Which let's you control the throttle with your hand.

You are right it is touchy, I guess I have gotten use to it. My brother in law drove it the other day to the gun range and that was the first thing he mention, man it has a sensitive gas pedal. JD nailed it a good return spring will make a big difference.

Also if you have a return spring on there already, you can modify it to be shorter. Mine had plenty of excess on the end so I just cut off the excess and bent a new end with a pair of pliers. Tightened my gas pedal right up. I too did that the same day I bought the Jeep.

It doesn't hurt to have 2 springs on it. If you've ever experienced a broken throttle spring you'll understand how fast it can get exciting!

Thanks! I will check to see if I have a throttle return spring... if not, I will get one and mess around with it till I get it right. I appreciate the info!

Next time you're off road, try bracing the right side of your foot on the transmission tunnel. If you keep your foot stationary that way and apply throttle pressure with the left side of your foot, it'll be a lot more constant.

This is exactly what I do also. Well said!

I am happy to know I am not the only person who has this problem.... My jeep does have a spring on the throttle body and I may experiment by putting another one on that is stiffer to see how it works. Right now, I am waiting for my new tires to come!

Yea, I'm having the same difficulty. I just purchased my Jeep and this drove me batty the first day. I've noticed the throttle linkage is poorly designed. Apparently, the Jeep engineers didn't do their homework, or got lazy.

The throttle cable is attached directly on the throttle cam in a strait line. It should wrap around a circular pulley or cam so the peddle input and cable movement exactly match. This existing mechanism, in effect, applies the greatest amount of gas at the very beginning of the throttle. Thus a very difficult modulation at low throttle and idle. Ideally, for 4x4 crawling use, the pulley should actually be parabolic in shape (instead of circular) to allow less throttle movement at first, right off idle, then more later. Take note of other throttle linkage on other cars. They at least have circular pulley cable attachments.

I'm surprised some innovative after market company does not make a replacement throttle linkage. Of course, I'm surprised Jeep, after all these years, has not picked up on this design flaw.

That is the explanation for why this happens, but I don't have an easy solution . . . sorry. I guess we can try some of those other helpful suggestions. I'm new. I see I'm really late on this post.

Strangely enough, the best fix I've come up with is to remove the pedal. With just pressing on the armature, it seems to work a lot better

Another one of those things I never really think about looking up / asking about on the forum so I'm glad this one came back up! Where is everyone getting the spring to add to the throttle body?

A hand throttle mounted on the transmission shifter is an excellent solution for that issue, any bike shop can provide the parts which is nothing more than a gear change lever and cable long enough to reach the bracket on the throttle body.

Instead of your foot bouncing on the gas pedal, which I have experienced myself, your hand rests on the gear shift handle and you control the engine RPMs with your fingertips... it provides for very smooth/even control of engine power which can also even prevent drivetrain damage by reducing shock loading.

Here's one source if you don't want to visit a bike shop... TeraFlex hand throttle kit



The below are my two installations... it was so useful on my OE 5-speed transmission in the first photo that I added it to my new automatic transmission after making the conversion.
