attention supercharged guys!!
smitty brought it to my attention as i have had hiccups so i soldered in my esm like smitty and other guys.make sure you solder that esm it makes a world of difference my car idles much better now and is smooth as glass.those connectors are not sufficient to make good contact thats why they have to be soldered!!!

FYI -
Since I had the ESM/ECU connections soldered two weeks ago, my gas mileage has improved by 2-4 MPG. This makes perfect sense since the previous loose connections were causing the ECU to add extra fuel.

Not saying what you experienced is not possible... just trying to understand it

Beyond that, an electrical connection is an electrical connection - possibly yours was loose and/or intermittent?

I also agree that this was probably more of an intermitant connection issue. I had an issue with the ESM connections last fall but they were more dramatic than what was stated.

BTW- do you know if the installers soldered the ECU/ESM connections?
Better yet... bring you car into CompTech for that dyno you keep promising and have them look at the ECU/ESM connections.

I just soldered my connections, normally when the car is cold it would sort of lope, now it's very smooth, even after the car warms up. This should be archived

As I previously stated; even though the behavior regarding the hiccups was intermittent that only happened typically under a certain temp range (75-81 deg.), the previous bad connections were constant; meaning there was always a slight resistance present that caused a lower than normal voltage. According to CompTech, this was causing the ECU to add just a little extra fuel unnecessarily. Under certain driving conditions and within a certain temp. range, this caused the plugs to foul that led to misfires.
In summary (IMHO), I believe that my car was burning extra fuel most of the time with the poor ECU/ESM connections which caused a loss in gas mileage.
