Hesitation at 5psi

[shogodz89]

Having some issues getting my 88 Tbird running again. I recently let it sit for a long time as I was waiting for some parts to come in and now the car won't run well at all.

Symptoms:
Rough idle, runs pig rich (idle and cruising).
Wants to stall
Boosts to 5psi, hesitates, then stumbles for a bit, then boosts to 10+psi...but very slowly.

My turbo usually spikes boost very quickly, it's acting as if timing is being pulled on the high end as soon as I get to 5psi.

I DO NOT HAVE A KNOCK SENSOR.
Brand new ACT
New TPS
New VAM
New Dissy/rotor/cap
New ECT sensor

Here is the weird part.
I disconnected the VAM, and it ran fine...for the most part.
It drives fine, with some decent A/F ratios. It boosts to 10psi (no matter how much I close my boost controller). There is a very obvious loss of power on the top end (I have a hard time passing hybrid civics on the highway).

Someone at Merkursport said these are the exact symptoms of EEC failure.
Any truth to this?

So in a nutshell, it runs like nuts with a VAM, and is drivable without a VAM.

Scan for codes.

After wasting time testing VAM's and looking for a spare LA3, my friend noticed that my throttlebody charge pipe wasn't on completely.

I tightened the clamp back up, and voila.

Oddly enough it produced enough of a leak to mess up my car with a VAM, but make it run perfect without one....weeeirrrddd.

Well, too bad he didn't see that before you bought all the new parts

Well at least I have spare parts now
