Split Air Solenoid
Ok, I searched and found alot of stuff but confused myself. Had an ECU looked at and the guy said I need to replace the Split Air Solenoid. There were no codes. Do I need to replace this solenoid? I read (I think) that it is used only up til the first 20K to help feed air to the cat or something like that. I do hear some slight backfire when decelerating. Thanks

The Split Air .Solenoid is functional only when in fifth gear. Per the FSM. If you have a automatic transmission there is a little more.
The Port Air Solenoid is disabled after 20,000 miles.

yeah, i believe the split air is what goes to the cat to help it heat up. But how can a solenoid be in an ECU? Its true that ecu's have a certain type of relay to engage certain circuits, but they are called "latches"

Oh! I actually read the post. I think what the guy is referring to is that the Split Air Solenoid wires are probably shorted to ground and caused a ECU problem. Check the Split Air Solenoid wires at the solenoid. See the fsm.

Thanks, I'll check them out later today. Visually they (wires) looked good-going on 16 years I've owned that car I never noticed those solenoids before!
So, I need to make sure they are not shorted or change the solenoid before starting-I assume it would mess up the reman ECU? Or can I still rive? Obvious I dont know electrical

You could disconnect the split air solenoids plug. Follow the wires from it to the plug.
Even if it shorted out most probably just the electrical device in the ECU that puts a ground on the solenoid would be effected and nothing else. You probably don't have a meter so there's no sense in asking you to ohm out the solenoid and then seeing if either of the wires is shorted to ground.
You could buy another solenoid that you know is good and unscrew the old one and install the new.
It's odd, because if the solenoid was or had been shorted to ground, I'd think the fuse would have blown and caused all sorts of problems.
