We pulled my b16 cause it wasnt making compression and put in a gsr motor. It idles like poo if at all. I have the throttle cable pulled a little open so it will idle. It will idle steady at 1500, but not lower.
Checked and cleaned IACV, New plugs. Old plugs were black.
I have a p28 Chipped disabling the O2 sensor.
Im lost.
No CEL.

Is it chipped for the GSR or the B16?

ay_billy

Ive tried 2 ecus one for my b16, one off my buddies gsr powered ek. No changes

ay_billy

Update as of this morning. Disconnected map sensor. Idles smooth now, but obviously CEL came on.
Does this mean I have a vaccuum leak?

Could be a faulty map, try and use a known working map. Running no 02 sensor with a diff map in ecu can make the gsr run rich. Stock intake manifold?

timing dead on? try advancing if its not.

ay_billy

Everyone I know with a honda isnt home cause the damn weekend. errr. But im going to borrow another as soon as I get a chance.
All the map part numbers are the same right?



Im going to rent a gun in a bit. I know the timing was dead on when i got it back, but im going to try to advance it a little to see what happens

Hseries, B series & D series are all the same from my own personal experience.

DontTouchMyEj1

you got a vaccum leak, my car was going through that a few weeks ago.
our throttle body might be leaking, i just slapped on a spare one i had and it ran fine idling at 700.

ej1b18c1

Use another b-series map and check for all vaccum leaks/tb/im gaskets

delsolo95

you sure the tps and map arent switched

ay_billy

I cant find a leak anywhere. Why b series? Autozone has all the part numbers the same.??
I can find a leak worth a **** though.

I thought the same thing, but i looked up the wiring, and its the right colors.


Thanks for your input guys. Im hopung to get a few maps later. I cleaned mine out and nothing

ay_billy

Ok so i got 2 more map sensors. No change. I noticed the PCV system isnt connected. I cant even see where the line should go on the manifold.

Former User

A vacuum leak would cause a high not low idle.

Is the idle speed low only when the engine is hot?

Does the IACV work?

Have you tried adjusting the idle speed?

Regarding running rich, the engine will naturally run rich if the O2 sensor is disabled.

My car does it cold or hot.
IACV works. Cleaning and swapping it for another one made no difference.
If i adjust idle by the screw all the way up, it will stay running at like 400 rpm.

ay_billy

Thanks a million.
I cannot for the world push the new one in.

ej1b18c1

you take off the intake manifold? might be a tad bit easier

ay_billy

Thats sounds like a lot of work. lol

ay_billy

Got it on. No difference. :\
Bump.

Former User

This^ doesn't tell you whether or not the IACV works. If you unplug the IACV, what effect does it have on the idle speed?

You need to follow the service manual procedure for adjusting the idle speed.

ay_billy

i was under the assumption that iacv would make my idle crack high or erratic if bad, not low? Am I wrong?
And i tried to unplug the iacv and set the idle but it wouldnt stay on, so? Should i try it with the map disconnected too? Cause it will idle without the map connected.

Former User

Yes, you are wrong.

Are you saying the idle speed dropped lower when the IACV was unplugged? Find the service manual procedure for adjusting the idle speed of your specific engine.

No, that will not help.

Have you measured the resistance of the ECT sensor when the engine is hot?

Have you tested the output voltages of the TPS?

ay_billy

No it just wouldnt idle at all connected or not. It does not stay on at all unless i have the map disconnected.

No I have not checked the TPS or ECT yet. The TPS was next in line after i remember to find my HB multimeter.
Ill search for the way to check the ECT

Former User

With the MAP sensor plugged in, can you keep the engine running by pressing down the throttle pedal?

Are you sure all the sensor connectors are matched with the correct sensors?
