normal life of a CPS?

That sounds like a classic case of a failing cam sensor.

It can't hurt to replace both, but FWIW I agree with airbag faceplant in that your symptoms sound like those caused by a bad cam sensor.

I have all said bolts in front of me.

The CID and DIS bolts are the same (13/16" in length), but the integrated flat washer is larger on the camshaft sensor bolts.

I have both of the camshaft sensor bolts in front of me. Based on my memory of the DIS bolts, I would not use them as a substitute. The camshaft sensor bolts are both different in design as well as longer in length.

One, the camshaft sensor bolts have a turned-down shaft to make them easier to start.

Two, in addition to being longer, they have an integrated washer that is larger in diameter than the shoulder of the hex head on the DIS bolts. This is to prevent the bolt from pulling-through the plastic sensor housing, as well as to distribute the load to prevent the plastic housing from cracking.

The bolts require a 7/32" (5.5mm) socket.

I was going to ask if you'd be willing to part with those treasures that you speak of, but I'm told that there are a couple of SHOs at the local u-yank it, I'm going there in the morning

thanks for the help everyone:thankyou:

If you don't find any, let me know and I can stick them in the mail.

I have a similar problem, you see when my tach drops to zero, the engine still idles and drives fine, no bucking, power loss, hesitation or dieing.

Ask GuruComputers about that one, it sat idleing in his driveway while we talked shop for nearly thirty minutes and never died, I even drove it home, and on the way home the tach picked back up and no problems after that.

When I did shut it off after getting to his house (tach dropped to zero on the way) it was a hard start, but still fired up and ran fine...

:

The problem you report has been reported several times in the past. There is a systemic problem somewhere other than the CAM sensor or the CPS. But nobody has been able to find it yet! It happens on my car occasionally. I've been able to verify that the signal from the DIS which feeds the tach and ECU is active when that happens, and it is active at the harness connector located below the vacuum reservoir for the secondaries. I have not been able to trace further than that because the thing will start working again before I can catch it.

I think your hard start was unrelated. But change the CAM sensor and see what happens since it is neither expensive nor difficult to change.
