Ok Finally got me B4 running

Installed timing belt kit, all markings are spot on. start it up and engine light wont go away. revs sit at about 2000 rpm.

Work iv done, 

Removed Intake manifold to replace broken intake duct.

Replaced Oil and water Pump.

Replaced Timing belt and pully's

Replaced Oil and coolant.

Removed and Cleaned Throtel body 

Any ideas?

Im hoping it just something left disconnected

OK its reving at 1500rpm without touching the throttle but if i press it down just a little it starts reving up and down on its own at about 500-1500 rpm.

So im wondering if its any of these

Throttle position sensor

Idle air control solenoid valve 

Pressure sensor

make sure the air idle control valve is installed the right way around.. ive stuffed this up before.. sounded like a lumpy cam V8 lol

nah defeantly the right way. but if disconnect it it pritty much dose the same thing idling at 1500 but dosent rev up and down when touching the throttle

Sounds like you might have a vacuum leak, just check if you've left anything disconnected, it'll be a simple fix

Well the engine light is on so it has to have something to do with it. but i dont have OBD reader to find out?

anymore idears?

one thing i can think of was the Throttle position sensor. is there a way in installing it because when i put it back on it dident line up neutral with the shaft so i had to throttle it a bit to get it in the keyway.

Problem solved. Stuck IACV. Taped it with a hammer and problem solved.
