Please Help Me With Timing
I am home from school and can work on my car now. I have a timing gun but I am not sure if I am doing it right. I painted the balancer line so I can see it but my timing tab doesn't have numbers on it. Also what exactly do you unplug to set the base timing. I unplugged the distributor (not the one that goes to the coil) but the car won't even start. So I unplugged the little gray plug that is close to the coil. The tach doesn't work when this is unplugged, but there isn't a check engine light, which I thought there should be. I think I am close. I have no knock and the idle is great but the car has TREMENDOUS hessitation. I have the light right smack dab in the middle of the timing tab. I am not sure if I disconnected the ECU correctly. Pleae help.

The plug that you need to unplug when you set the timing is on the passenger side firewall. It's a little brown wire that comes out of a bundle, has a little connector, and then goes back into the bundle. I hope that this helps.

you sould have numbers on the timing tab, if it is stock. I couldnot see mine on my lo3 so i took a metal brush and scraped it off intill it turned all silver and i could see it. about hte pluge you take off to set timing it is the est wire it is a single pluge that is located over by the strut on the passenger side or up on the firewall, around in the ac stuff.

Thank you so much guys. Imagine that...the dealers didn't re-time my car right. It was dark when I went out and checked the car but my EST connector looks closer to the strut assembly and not right against the firewall. I wish I could reach through this computer and shake your guys hands.
