Engine Surging
 
Has anyone else had the engine surge really bad on full acceleration? I went through the break in process like normal, but now when I accelerate past 3,000 RPM's the Hemi feels like it is getting an extra wind. It keeps surging every 500 RPM's until it reaches the red line.

it surges/accelerates without you pressing the pedal?

No while pressing the pedal. It is almost like it has a old turbo and it gets bursts of power. Once you gun it, it feels like a burst, then another burst, then another burst. Its not the transmission either since it isn't shifting during the surges.

Is that done by taking the terminals off the battery? Is so that'd be a fun job on the new location.

Can you point me to that? I'm having trouble finding it.

Thanks.

Here's the steps you need to follow:
1. Find an unused section of road with a good spot to pull-off/turn-around.
2. Pull off of the road and shut your car off.
3. Turn your key to the "On" position (but don't start the car), and wait for the 'idiot' lights to go out.
4. Press down on the accelerator, and let it back up.
5. Turn your car off.
6. Re-start your car and cruise up and down the road testing your throttle responsiveness.
Depending on how fast/slow you do the 4th step, your throttle will either become more or less sensitive/responsive.
Repeat steps #1 through #5 as needed until you're satisfied that your throttle response is as good as it's going to get.

Remember these things 'learn' how you drive so if you drive like Grandma for a few days, it's adjusts accordingly.
