I had a broken hose on the roll-over valve that was giving a P0455 on my '97 855. I replaced the hose and the problem was solved.
The P0410 (Secondary Air System) code may be due to a seized air injection pump, disconnected hose or a SAS valve on the exhaust manifold that is stuck open.

will the p0410 code give me problems that will keep my car from running or can I wait about a week or so before fixing it after I fix the rotted off hose.

My experience was that the P0410 code posed no problems in performance or driveability other than turning on the Check Engine Light. The secondary air system reduces tailpipe emissions during warm up and sometimes at idle.

Sounds good. The P03xx codes (p0300-random/multiple cylinder misfire detected, p0302- cylinder 2 misfire detected, p0304- cylinder 4 misfire detected) should get attention as soon as you can because misfires can lead to unburned fuel getting into the catalytic converter, which can lead to expensive damage.

Abs/tracs module is bad and needs to be re-soldered.

Pm Matty Moo about abs module or search the abs/tracs module re-soldering thread here on the forum for more info.

I had an ABS and TRACS light on after every start. I fixed it though with a new switch behind the ignition switch cylinder.
I arrived there because after starting the engine the ABS and TRACS lights went out after jiggling the key. And doing that was the only way to release the transmission lock to get it out of park.
So just another thing to look for on those lights.

It was at least the second switch replacement on this car. I don't know the history of the car with respect to the weight of the keys used in it by the original owner.
