2.3L timing...

Can someone walk me through timing the bird....

I know i pull the spout connector, do i set the crank at 10 degrees BTDC or 15 Degrees BTDC?

Then I line up the cam timing marks.

Ensure the distributor is pointed at 1 ( or is it close to 1 but not on it?)

Put on the timing belt.

FIre it up?


is this all correct

I would personally read the write up on NATO. Its good, and I've used it before:
You are confusing igntion timing with cam timing.  Set cam timing first, then set the ignition timing AFTER the cam timing is correct.

nope that is not correct.
1st you set crank to TDC
2nd you set cam to TDC.
3rd make sure rotor is pointing at #1
4th put on belt
5th make sure crank,cam,rotor all pointing where they should.
6th tighten everything and button it all up.
7th pull spout connector
8th start her up , might have to wiggle dizzy to get her to pop
9th warm her up nice and set the base idle with the idle air controller not hooked up.
10th hook up the IAC and connect timing light
11th set base timing at 10btdc on 5sp and 8btdc on auto's
12th plug back in the spout and take her for a test run.
13th Double check the Throttle position sensor(TPS)  is set correctly .90v-.97v should do it
14th get back to the shop time to pick up while enjoying a Beer!

1 didn't know these 2.3t's had a CAN where I gotta go! Yes the cam timing marks are those on the lower right of the cam gear area. It should be almost pointing at the center mark. If your marks are borken or you just want to Use a straight edge centered on the cam bolt and Aux shaft bolt and there you go. Line up the cam gear mark with the straight edge.

2 Yes and Yes you gotta have the engine running to set the idle! Don't over look the TPS setting.

nope my marks arent "borken"... this really sucks not having a timing light... which way do i turn the distributor to retard timing... is it counter clockwise?

You should not be attempting this without a timing light.  Lights are not expensive and easy to get.

Get one.

how do i set base idle though im real foggy on the process. Could base idle cause the popping i was hearing?

that popping sounds like its out of time. At for setting the base Idle get her running. unplug the IAC then turn the screw on the throttle body to get the idle set. The screw is on the linkage side. It could be in 2 different locations but both are on the same side of TB.

sounds like you need to turn that screw that hold the throttle plate open. at least enough to keep it running.
