30 seconds cold idle fixed ...

[HighMileage]

I definitely suspected the EGR spacer for which Ford created and updated part (I believe) a few years after 93. Well, I was planning on replacing that, except ...

I did recently clean the distributor, which naturally changed ignition timing a little. Rather than timing it the way I usually do, I just reduced the timing (counterclockwise) with engine not running.

This alone eliminated 90% of cold idle tremble during the first 30 seconds.


I guess I've been running too advanced.

Part throttle under load clicking is now completely gone, just smooth power delivery.

Hey, if it works, run with it...

counterclockwise is advancing not retarding. if im wrong someone please correct me, but i just timed mine and this is how mine worked.

Other way around.

Highmileage, if you don't have a timing light, you don't know where you were or where you are now for timing. Pick one up for $50 if you plan on working on your own car

so clockwise is advancing???? i just did mine two days ago, and it was sitting at 10° i turned it counterclockwise and got 14°. whats up with this???

You have to double check. It's impossible..I think.

Did you remove the spout before you set your timing WildStang? If not, maybe the computer was compensating for the change...

Heh, heh ... you're right, I don't know where the timing was. Plus, I don't know where it is right now either. At one time I may have over advanced the timing and never noticed the clicks on acceleration. Acceleration doesn't feel as aggressive but cold idle is much better.
