Anyone? Please help this has been bugging me for a while!Im i trying to do ignition timing wrong? What should i look for?

 

Might help if you tell us what you've been doing to try to set your timing.
You know you have to jump out the service connector to make any ignition timing adjustments permanent, right?
If you're not jumping out the service connector your settings will stay until you turn the car off and start it up the next time.

 

Well lets say how do you set your gun for timing?

Ok so its suppose to be set at 16*btc so I'm guessing my gun is suppose to be set at 16* also right?Well if that's the case I can't get my timing right.What should I do next blow up my car

No... if you have an adjustable gun you set it to 0 and you should be lining up the pointer and center red mark by line of sight.

You have to jumper the ECU to put it in diagnostic mode.

The car has to be warmed up completely, all electronics turned off, AC off, and wait until the radiator fan isn't running.

 

to answer your question... one of the top things to look at is the cam timing. the distributor rides on the end of the cam. if the T-belt is of a tooth or more then the dist. will be off also.

on some models you can get the rotor in the distributor turned 180 if you took it off. but i don't think you would even be able to start the car like that.

but yeah... like some other guys said, jump the connector, set your light to zero and check the TDC mark between the 2 degree marks after the car has warmed up (A/C, fans, headlights all off). you also want to be sure your idle is around 600 rpm. normal you know...

 

WTF?? Some other guy told me i was suppose to set it a 16* as in put my gun at the 16* mark.WTF&lt; have i been doing it wrong? So let me get this straight i have to set it at 0* and piont it to the timing thing at set the red middle mark to it right?Thanx for all that have helped and im sorry if i have been doing it wrong but some dumbass guy told me that was how it was done

 

if you set your gun @ 16* use the white mark

If you set the dial on the gun to your desired timing (16 Degrees), use the white mark, that is the TDC mark for the crank.

If you set your gun to 0 Degrees, or if you do not have an adjustable gun, line it up with the red mark on the crank pulley, that mark indicates your timing spec.

It doesn't make a difference either way if you do it right, just depends on the equipment you use.
