Update, more questions
 
Got it running, but of course not %110 trouble free.

The problem was timing to get it going.

However, I cant get it to idle with the airbox/AFM sensor connected. I had to hold the throttle open manually, opening it more and more every few sec. to keep it running.

But she idled fine on her own at +/- 900 rpm with nothing connected before the j-boot. (Including the airbox.) She was burning a bunch of oil....exhaust was nice and thick. (See my previous thread on oil in my intake.)

I started her up first crank a few min after the first session (again, without the airbox/AFM sensor in place,) to watch the idle, and she just died abrubtly after a solid 10 sec. or so of running. Immediately after I tried starting her up again but nothing came about. None of the cylinders fired, but I got a trickle of smoke coming through the j-boot.

I wanna say timing but...how? That belt was, dare I say, pretty darn snug. I was thinking the smoke could be the oil residue in the intake burning off after it heated up?

Questions? Comments? Answers? Thanks again guys!

I would check that AFM. Check resistance to spec. etc.....

A friend of mine had a 92 Dodge Stealth RT non turbo and his car had the same symptoms. Unpluging the AFM helped but it ran terrible. It all started because he messed with it by trying to put a cone filter on with an adapter. He thought it would be a good idea and help with flow if he removed the metal honeycomb insides that actually help the AFM read the air.

Not that you even touched it, but it seems to be the source of your problem the way you describe it.

I hope this helps.

Timing is set by the computer and there really isn't a way to adjust that...providing the belts are on correctly. I agree with Gremlin...check the AFM by the specs in clarks garage.
