P1613: Auxiliary input, Auxiliary output control; autozone said it's the speed sensor. Where is this placed, and where might I purchase one from?
P0134: No activity Bank 1 Sensor 1; said it was the sensor right before the cat. Autozone carries this part and quoted $159.99. Do these diagnoses sound correct? These codes only come up when I put the chipped ECU in. CEL goes off with stock ECU in.

Autozone is stupid.

Your front O2 may indeed be dying.

The P1613 is just a MIL request from the TCM in regards to a voltage problem. You must interrogate the TCM in order to properly diagnose this fault. It could be something as simple as the TCM seeing the ECM being screwed with when you change ECMs around improperly.

what is MIL and TCM? When coasting in nuetral, the RPM's drop down to about 500, but at a dead stop, they're back up at 750. The guy at autozone seemed rather knowledgeable. What is the proper way to insert the ECM's? I went off a set of instructions for Wetteruer ECU install.

MIL=Malfunction Indicator Lamp=CEL=Check engine light....all the same thing.

TCM=Transmission Control Module.

If you swap ECMs with the key OUT of the car, you shouldn't get any faults except for possibly throttle adaptation codes. The dipping throttle you describe could be due to not having done a throttle body adaptation after the swap.

Also, removing and installing ECMs in general is a very risky proposition-ever look at the pins in that thing? How much pressure do you think the female parts of the harness can exert on the tabs when they are that tiny?

what role would pressure of the female connectors play in this situation? Electrical connections do not matter upon the force they are touching at, but how clear the connection is between the two points. Maybe some of the pins need to bel cleaned. This chip has seemed to do nothing but problems, and it doesn't seem that someone switching out ECU's with a tuned chip commonly has different problems than with the stock ECU. Could this ECU, or even the chip be defective?
