Hey guys. I have a 95 integra gdr with a b16b head. Stock Exocet skunk2 dual springs and valves. When the car sits for 4 hours or more, I start it up and the tac falls immediately and the car dies. Also the car is running very rich. I can smell has and see some white smoke when this happens. i have to hold the gas down for a little bit, once I do it will stay running.
The car also hunts for an idle, After I can get it idle. It sometimes idles at 2000, 1000, but mostly hunts for idle between 200 and 400. I'm beginning to think that I have a fuel injector stuck open. I'm going to clean the iacv because this is a common problem I see. I have done a lot of searching and have an idea on where to hunt around. But any input or thought would help.
Lastly I noticed oil leaking between the head and block. It having a mild head build on OEM head bolts im am wondering if they are loosening. Thanks in advance for any help

 

Anyone?

 

Is this thing tuned? Is the check engine light on?

 

Bad fuel injector(s), bad MAP, bad Fuel pressure regulator......is there a CEL like other poster posted? Check your plugs first.

 

Plugs are good. And the cel finally came on today. Throwing a iacv code. I cleaned the iacv and out 12v to it outside of the car. It's operating within factory spec. I found some new information

This motor has a CTr b16b head with some valve work done on stock gsr cams. But he out on a p73 intake mani apparently. And an obd2 tb. Said the start and die problem happened when he put the tb on 8 months ago.

I dknt understand how it is throwing an iacv code when the iacv is working fine.

 

Also no tune

 

Scratch that. The person I traded said yes it does have a tune on it.

 

after fixing the cel problem, id verify the tune on it. Wouldnt hurt to clean the throttle body out as well

 

He said the problem started when he put on a obd2 tb.......so change it to an obd1.

 

I went to do so. Gotta get ahold of a gsr throttle cable bracket. The one that's on the type R mani is different. The valve on the tb is upside down. Gonna get that done this week. Still can't figure out why I'm throwing an iacv code and the iacv works.

 

Some one probably plugged in the wrong connector to the iacv and blew out the circuit in the Ecu ...assuming u reset the Ecu and the code stayed there every time

 

New information. The throttle cable sticking or throttle body is the reason for the high idle. Iacv still on. Goin to reset it today. I don't remeber if I said this but I found out that when he switched tb from obd1 to obd2 he move the tps sensor as well. Sense it was tuned and that is when it started this issue in wondering if that is my problem. Another idea is the fact that the obd2 doesn't have an fitv, or at least it was explained to me this way.

 

You probably should get ARP head studs. In the meantime, it won't hurt to wait for the motor to be cold (overnight), pop the valve cover and grab your most accurate (new) torque wrench and go through the torque sequence in the FSM for your B series motor.

Usually a re-torque isn't necessary but if you suspect things are amiss, the piece of mind of going through it doesn't hurt. Might not change anything but then at least your know all the bolts are at least at minimum torque (you won't know if someone over torqued).

Whatever you do, don't loosen any of the head bolts though. Once the HG is heat cycled it can't be reused. Loosening bolts is in line with reusing the gasket. All you want to do is be sure all head bolts meet the top torque spec for the head bolts for your b series motor.

 

Thanks for the advice on the headbolts. I will do that tmrw after work for sure. Good idea.

Got the obd1 throttle body on and it no lingers idles at 200 or 300. It idles at about 1000 now...but, when imnslowing down or tap the gas at idle it sits at 1500 ands reva up and down but doesn't move the rpm needle. I have a video that I am trying to upload. But it idles a hell of a lot better, other than the the weird idle at 1500.

 

Okay I am resurrecting this thread do to the fact that I have solved a lot of issues, as well as found new ones.

My cel for code 14 is still on, after reset it came on immediately. I tested the ground on the ecu with a multi meter a little while back and it was wayyyy out of resistance, the oHms were very high. Pulled the ecu today and opened it. Found a burnt spot on my ecu, q31 is the sensor that has been burnt. Not sure what to do now to fix this issue.

But I have got my idle to be so much better since installing the obd1 tb. Still has a low idle on cold. Obviously code 14

The car runs extremely rich the O2 sensor is not plugged up. Having an issue with getting it back out. I have learned that the guy who owned this car before me rigged a lot of stuff up. The O2 is welded to the bung........but I am assuming this is why I am running rich.

The ecu does show that it has been base map tuned. The tuner states he doesn't know why it is throwing a code. Apparently when he tunes them they shouldn't show cel codes anymore. I am not well versed in tunes.

The iat wires are jimmy rigged and they used cheap splicers to connect them. Probably why the transistor has a burnt spot.

I know how I am going to take care of the O2 part. But my questions are as follows

-where should the other side of the pcv vaccum line go into. I am having a hard time reading vaccum diagrams because they seem To differ between b16 heads and b18 heads.
-Would it be btr to buy a whole new harness to fix these rigged wires? And my iacv issue.

-can I run a stock ecu and the car run fine? Seeing as it has a head swap.

To remind people of what I have instead of them
