Ignition problems on 96 bronco

To give you the hole story from the beginning.
Last week my bronco just stooped running with no codes.
Checked for spark and there was none, next I checked the tac to see if it was bouncing while I was cranking it over and there was none.
I did some research and figured out it was more than likely the pip sensor in the distributer. I changed it out with a rebuilt distributer from napa and it started right up, great problem fixed right. I pulled the spout and set the timing a 10 degs BTDC and it ran good till I plugged the spout back in.
Now I get a flux in timing from 25 degs to around 40 degs and when I try to drive it, it pings like hell. So now you know my problem, do I have a bad distributer from NAPA or is there something else wrong maybe a ICM?

Mike

Are you absolutely certain you got the new dizzy in correctly? If you miss TDC even by a tooth with the engine management system it will NEVER be right.

Timing should be set on a warm engine. To be sure the PCM "relearns" disconnect the battery for 15-30 minutes. When done drive it 20-30 minutes in all conditions to relearn.
