alright i got the JDM D15B...well it idles descent and isnt even close to dying when the engine is cold but as the temp rises the idle gets worst and at full operating temp it shakes REALLY bad and tries to die.....yes i searched before posting and this is what i have done/changed from searching
It has new dizzy cap, plugs and wires, o2 sensor and fuel filter

I switched from a perfectly good running civic....MAP sensor, coolant temp sensor, ECU, injectors, fuel rail and FPR...still the same

I took off the IACV and the screen was clean, the fuel pressure is in spec 38psi at idle and 45psi without FPR vacuum hose connected, and I also bled the coolant system.....I AM GOING CRAZY!!!!

I did notice that when i pull the vacuum hose off the FPR it idles high of course but the roughness goes away but as soon as i put my finger over the hole in the vacuum hose the symptoms return.

Thanks in advance for your help

the only thing i have done to the tps was moved it till i got the best idle...i have not used a multimeter on it. btw how do you guys get to the red and green wires on the tps with the meter? what setting on the meter do i put it on...i shoved the probes where the wires run through the back of the connector on but i got all 0s.....does the d15b use a Z6 TPS?? because the one of my d15b8 will not fit.

Heres a video....this is the engine at operating temp

have you tied increasing your idle with that screw on the throttle body?

psychotic7

i turned the screw to the left until it didnt make a difference in idle anymore.....the video i took of the car was after a drive...so i know this much, it only happens when the throttle is moved a lot. i let the car totally cool and let it idle for like 20min and it was normal. then i started playing with the throttle and the more i did the wrost it got......in the above post i meant the IACV will not interchange, the TPS will and both that i tested did the same.

Plug wires in order? Fuel injectors in order? Check timing with timing light? Wouldn't be the first...

Here's my firing order
3
1 4
2
4-3-2-1 staring at the engine from the front
i am going to buy a timing light tonight and check that.....which mark on the pulley do i use? isnt there like 4 marks....3 together and one all by its lonely

I finally got a CEL code today....but WTF code 60!!!! I cant find it anywhere, what does this code mean

i think your firing order is wrong. try 1-3-4-2...#1 is to the left of the cap. not bottom.

EDIT: nevermind i got the way you typed it. yes firing order is correct but double check it. 1-3-4-2. if not then im in the same boat man. my D15b will idle only at 100 to 125 maybe.

I think what he meant with the firing order was
3
1 4
2
Does the map have a solid vacuum signal?

well if he meant it that way then its wrong. it should be 1-3-4-2 going clock wise starting at the left of the cap being cyl#1.

I cleaned all connector with electrical cleaner, let my IACV sit in carb cleaner for a few hrs and cleaned my fast idle valve and im at a solid 600rpm idle with no roughness....btw for good measure, how do ya check the MAP sensor?? thanks guys
