    I could not open that zip file; however I did find this image. It is a diagram of the timing marks for a D16W1 engine. My set up is almost identical

    What do you mean by almost? It should be exact. Post pics cam and crank.

    The horizontal cam marks most likely align with the top surface of the head.

    No photos because I've already reassembled the car. The marks are horizontal even though they do not match the engine marks

    Verify alignment of cam TDC1 marks with the top of the head. The timing may be off by one tooth or you need to adjust the idle properly.

    That was my intent. I will try again aligning the marks with the head instead of the triangles

    It's easier to check the cam timing using the TDC1 timing marks on the rear side of the cam pulley.

    Sorry for the late post, but I have some good news. I replaced the gauge cluster with one from a 98 Civic LX (it has a tach), the steering wheel, the VSS and adjusted the TPS. The car idles a lot better now and the gauges work; however the SRS LED stays on and the gauges are off (tach starts around 1000 -1200 and the speedometer about 30 mph).

    Did the SRS light turn on only after replacing the steering wheel?

    Sounds like the tach and speedo are bad in the cluster.

    I saw a video on calibrating the tach and speedometer. There was also on resetting the SRS. Going to try both tomorrow and update when I'm done.

    UPDATE:

    I verified mechanical timing Thursday. The car ran smoothly with the exception of a high idle and minor surge. It was suggested that I test the MAP by unplugging the sensor and see if the car continues to run. It did, so I replaced the MAP and throttle body gasket. The surge returned with a VENGENCE. To date, I have replaced the VSS, IAVC, TSP, PCV valve and the MAP (today). Anymore ideas?

    Oh yeah, the car has no CELs

    Iac on the back of the intake will do that, sounds like a surging dsm when its stuck. It can be cleaned to operate properly.

    I will check it tomorrow. It is dark out now. How would the IAC get stuck so quickly though? The new one has only been on less than 3 months and I do not drive the car often.

    When the idle is high and surging, remove the air intake. Cover the IACV hole in the TB with your finger. Does the idle speed drop to low rpm and does the surging disappear?

    I've seen that before on a YouTube video. Didn't think about it because I changed the IACV during our earlier exchanges. I didn't think they would stick so early. Unfortunately, I do not have adequate lighting in my garage to test the IACV tonight. Will post the results tomorrow.

    Please understand that the diagnostic test I am suggesting should lead you to the problem whether it be the IACV or something else.

    I tried it and the surging idle didn't go away; however there was a "sucking air" sound when I shut the car off

    There ya go. Locate and fix the intake air or vacuum leak and your idle issue should be solved.

    If there is a vac leak while idling spray carb cleaner or starter fluid around all joints, hoses and sensors, map, iac etc. Do not over spray and keep fire tools close. If the engine surges or revs you are close to your leak(s).
