I failed my emissions test and my reading are:
HydroCarbons (standard is 0.80) I got 1.83
Carbon Monoxide (standard is 15.0) I got 74.2
And after the test were done my car overheat too.
HELP ME OUT GUYS WHAT WENT WRONG.
I have a 95 GSR Integra
here's the specs:
1.) Skunk2 ecu with P28
2.) AEM fuel rail with B&M fpr
3.) Stock injectors
4.) Skunk 2 manifold
5.) DC 4-1 headers
5.) aem short ram intake
6.) jdm 5 zigen exhaust catback
7.) JUN stage 2 head package
8.) MSD whole set-up (ignition box, coil, cap, wires, etc.)
9.) Fluidyne radiator
10.) Fal dual fans
11.) Apex Vfac
12.) Stock buttom end

Help me out guys, I appreciate it

 

ANYBODY CAN HELP ME PLEASE

 

put in a stock ECU program for that engine. set the fuel pressure to the factory setting and check and adjust the ignition timing back to stock or even a little retarded.

as for your overheating problem........check to see that your thermostat isnt stuck closed or that your fan switch is accually turning the fans on. also check your coolant level and make sure it's full........

 

so i just need to put back my ecu , adjust my vfac, check my cat and o2 sensor if its vad or not

 

anymore suggestions, c'mon guys i need ur help on this one

 

Start by installing your stock ecu, readjust your fuel pressure to stock(35psi @ idle), and reset your timing to stock 15 degree +/- 2.

Also, fix your over heating before you retake the emission test; for, this will affect nox and hc reading.

Also, make sure the vehicle is at normal operating temp. cooling fan cycled twice.

 

how can u test if u have bad cat and o2. And now my car is throwing an check engine light.

 

ok guys i have questions again. How can u tell if it OBD1 gsr ecu 94-95 gsr to OBD 2 gsr ecu 96-01 gsr. They both have same code p72 but how can u tell.
And would a JDM GSR ECU will work on my car to pass the emission? PLease let me know guys Thanks

You have to have gas bench tester to test the cat. but however, you visually inspect the cat by tapping on the cat with rubber mallet - if the cat. rattles remove it inspect the inside with a flush light to if is damaged.

and, an 02 sensor can be tested with a DMM by back probing the input wire the voltage reading should switch from .3 - .8 volts within .5 sec and from .8 - .3 also within .5 sec. Now, o2 sensors are tested on close loop(engine at normal operating temp) @ 2000 rpm. no load condition...

but as far as to your ecm question, I don't know. perhaps some one else in here can help you.

 

thanks

 

recently i have a check engine light too and i brought it to acura and they told me they can't find any code for it. Is it beacuse of my Skunk 2 ecu.

 

take off the DC header it took me from a gross polluter to passing.

keith

 

Post the oxygen and CO2 readings, they are CRITICAL for troubleshooting emissions failures.

 

dc headers don't allow cat to heat up to temp...thus you fail sniffer all the time with dc headers

 

well i have a civic before and i have dc headers 4-1 and I passed with no problems. Someone told me i can't pass the emission because of my Jun stage 2 cams but i know some people with jun stage 2 and 3's na dstill pass the emission.

 

would the civic dx 92-95 ecu will work too?? Someone told me if i put that ecu i should pass with no problems. Is that true

 

anybody?

 

can i use the octane booster bottle that u can buy at pep boys. I heard that should help.???
