[quote=”chevyaz” post=152721]Is 9 degrees advanced to much for these engines? I checked the timing this morning. Factory specs say zero. I heard a little advanced is good. But 9 degrees sounds a bit much[/quote]
what year make and model are we working on?
[quote=”chevyaz” post=152727]Its a 1994 gmc silverado truck. 2wd half ton. Automatic transmission[/quote]
Factory spec is 0 as you stated. 9 deg is to much.
did the truck run bad at 0?I really don’t know. I wasn’t really savy about my mechanical ability till I met ETCGs videos. If you get what I mean.
The truck has been running good but alot of pinging. So i put a high octane gas at the last fill up and the pinging has been very minimal or not at all.

When you set the ignition timing did you disconnect the timing connector?
[quote=”chevyaz” post=152735]Ive never messed with setting it. And yes i disconnected the tan and black wire connection.[/quote]
Ok good. I would set it to factory and see how she acts.
I will do that sir thanks. I put a vacuum gauge on it and it read 20 on the gauge so im happy the engine is at least healthy. 315000 miles on it.
Nine degrees too much in the advance will not only cause pinging it can destroy an engine; especially during a sustained highway drive.
EGR system working? Any problem there can create pinging or make it worse.
I forgot to update you guys on my last post, I had the throttle body rebuilt snd put new injectors in it ,cone to find out the fuel pressure regulator was leaking for a while. Set the timing bsck to zero the factory specs and it idles like a kitten. So its running alot better. No more pinging. Thanks for your help.
