I've triple-checked my installation of the SEGR kit. I've replaced the MAF sensor. I still have a CEL.

With the SEGR plugged in, I am getting the following codes:

P0102; P0069; P1140

With the bypass plug connected, I get the exact same codes. In both cases, my code scanner also displays 'misfire' and 'EGR'.

I can never erase the P1140 code, and occasionally can erase the P0102 and P0069 codes, which come back immediately. I also noticed, that if I start the engine and then try to erase codes, the CEL goes out and immediately comes back on.

I'm totally whacked out by these CEL and codes issues. Also, since I moved the filter/head assembly to gain access to the wiring trough, I am getting a huge amount of 'limp mode' occurrences, with air in the fuel. I guess I disturbed the infamous fuel line fittings.
Signed,

Totally Frustrated!

You have the P1140 and P0069 codes before hacking into the harness?
The SEGR adds the P0102?

Yes, I had those codes before the install.

Because of GDE's tunes, not so many forum members are still reading these SEGR threads.
Since your trouble is not SEGR related, start up your own thread with the P-code numbers in the title.
Someone who has had similar issues may be able to help.

There are a couple things to check besides your SEGR install.

Is your EGR valve stuck partially open? Is your FCV valve stuck partially closed? Either of these can cause the MAF related codes due to unexpected MAF readings. Remember the SEGR still uses the MAF signal, it just modifies it to what the ECM would expect to see with the EGR still in play. If either valve is stuck, the MAF readings could be off enough to cause these codes. Also check your Vacuum Resivor solenoid connector and the vacuum filter itself too, not sure what causes that code as I haven't had that issue pop up.

On your SEGR install:

verify one more time that you didn't acidently swap wires 1 and 2, or 4 and 5. That error will drive you crazy as you swear you hooked it up right, but might have spliced onto the wrong end of the wire you cut.

Hope that helps a bit.
