Is it normal for when you set the timing on your car for the timing to go up as the rpms increase? i'm trying to set the timing on my 88 Throttle body 5.0 and when i rev it the timing goes up along with rpms then drops back down, Is this normal and could that cause a knock?

 

i don't know about the 88 but it should have a computer controlled distributor that you have to un-plug but yes it is normal for the timing to move around as the rpms are increased im more of a old school person ware you would just in hook the vacuum advanced hose,But your car is computer controlled

 

It's normal for a distributor to advance the timing as rpms increase. You need to set your timing as shown on this site and in the service manuals.

 

Yes, normal. You need to unplug the EST wire, then start the car and set base timing, then turn car off, replug the EST wire, and disconnect battery for 5 minutes to allow ECM to lose 'memory' and make use of the new timing info and 'relearn'.

 

alright thanks alot guys
