Ignition timing

Sluggish, more than normal!!

Ignition timing

Postby cwthemachinist [OP] » Jan 07 2013, 4:31am

I just put a crank postion sensor in my truck (04 Silverado 4.3). It has been sluggish and non responsive for a while. It used to be snappy with the throttle response, gas mileage is down the toilet more so than normal as well. I want to know if the ignition timing can be set in the traditional method, timing light and rotate the distributor. Is there something else I need to do after putting in a crank sensor. I have read about relearning the computer.. a "case" relearn?.. Any help please?... Thanks!!

No, you can not set the ignition timing like the old ones. If you moved the distributor at all you will have to have someone with a diagnostic scanner (not a code reader) reset the camshaft position sensor to it's correct location.

So with the diagnostic scanner, can I figure out where the timing is set now and possibly advance it to the correct position? Thanks man..

You actually will not be setting the "timing". You will actually be setting the location of the camshaft position sensor. The computer will adjust the timing based off of that.
