I think you have to clear the code that exists before the problem is corrected...

You have to clear the codes first. Just disconect the battery for a few minutes.

when i put mils on my car, i disconnected the batt. for like 30 minutes to restart the comp and it shut it off for about two days, then it come right back on....idk why this happened. everything is hooked up properly and the cel still comes on. im about to order a programmer to shut the o2's off completely

But you still need to clear the codes

Mach1Man04 · 03-13-2009, 08:42 PM

so just to be clear, i have to have some one use a tuner and clear the codes???? then disconnect the battery for like 30 mins???, then install them and put the batt back on. and does it matter i have both mils plugged together on the driver side???

Clear the codes at Autozone. Just ask them for their handheld and take it out to your car.... plug it into the computer, clear 'em out. wallah.

But, you did say you have your mils hooked up on the driver's side only? You mean your front and rear driver's side? You're supposed to plug them into the two rear O2 sensor ports. Your two front sensors should still be hooked up (you should have extensions for them if the stock sensors don't reach. I don't know the specs on your midpipe as far as length to the O2 bungs are concerned) in the first two bungs.

I'm sry I should have been clearer I have them both on the drivers side rear sensor the rear passenger reached fine for some reason

Scott McClure · 03-14-2009, 08:04 PM

Casper, I can clear the CEL for you if need be.

Have the codes checked, it might not be throwing a code for the cats if you have disconnected the battery and hooked up the MILS properly. I was able to clear a P1000 code by disconnecting the battery so I know it will clear anything else.

+1 on going to autozone or advance auto, get that code checked out.

He doesn't need Autozone or Advance. He's got me right around the corner and I can scan and clear any codes for him.

There you go, sorry I didnt read that. He should check what the code is though, its very odd that it would shoot a code with a MIL.

Some times you have to get a tuner or a tune to keep the CEL off. MILs don't work on all cars.
