20v black top bogging! Don't no why. Can some 1 help?

[dominican]

I have a black top dat Boggs wen I try 2 go faster! I'm thinking wat is causing this is dat
It has auto ecu! Can it b dat?
Nd it has a gas tank off a 85-88 Nissan 200sx tank nd fuel pump?
I adjusted da timing but no change! I have most of da vaccume lines plugged too?
I just don't no wats going on? Need help!!

Should run fine with auto ecu -if everything is wired correct-

Try and see if your VVT works. If not, my best guess is the VVT transistor is blown.

From my experience, here's what I've seen go bad:
-transistor in the ECU burns up (see above link)
-incorrect MAP sensor used
-knock sensor is bad
-incorrect ignitor
-20v distributor caps suck, they burn up often. Look inside to see if there are white/grey burn trails.

The coils are all pretty universal. If it fits, it ships. I've rarely ever seen a fuel related problem other than the fuel pump is going bad, but that is usually a "it runs or doesn't run at all" kind of thing. 95% of all 20v bogging problems are ignition related.

Thnx 4 ur help!! I checked da vvti transistor nd is no blown nd very thing els look good!
The cap does have burn marks on 1 of da plugs!
Nd da resiter for da igniter is bad so I just put a wire looped around nd it starts up right but if I plug it corectlynit doesn't even start I'll try to Chang it c wat happens!

Which cap? One of the capacitors? They are prone to leaking (apparently there as a bad batch used) and if you notice any signs of leaking I'd advise you to replace them before the ruin the whole PCB.

Did you hook up the STA wire to the ECU? Without that wire it causes bogging. Anyone correct me if I'm wrong, I believe that the ECU is on but only wakes up when it see's this STA signal wire. Like when you log off a computer, technically its on, its just not fully functioning?

Which 1 is da STA wire??? Nd I ment da spark plug cap! But i don't no which is da STA wire cause li I said I looped a wire on da resistor dats on. Da coil bracket is dat da STA?lol

It's the wire on the 22 pin connector (second biggest) on the top left. you basically run a wire off the starter switch wire to that wire on the ecu. It only needs to see that the car has cranked.

Have you messed with the throttle position sensor or ignition timing? I think you should research no one wants to spoon feed anyone on here. Not being a di ck but this has been discussed on just about any ae86 forum. Google is your friend

Lol! Thnx for da info da diagram is good help tnx!
