ok so the project is now finished and i have some pics that ill posting up shortly because it was a fun build.. its a 99 cx with a obd1 GSR motor,EX wire harness, snk2 intake mani, running Jdm -72 (GSR ECU) +++in it// all conversion were made so it would work/ harness, dizzy, plugs, alternator, etc.

> i need some trouble shooting help with why its runs harsh,, when i start it_ it will lobe as if there are cams (4 ppl that know that sound) or the idle fluctuates little bit .. im guessing i have a vacuum leak cause the only code im getting is one and thats the O2.. ive changed the plug on it changed but just havnt changed the sensor(will do tomorrow) but i also think that you can throw this code if there is a vac leak

my question for everyone that is good at trouble shooting is what else could i try so that i can hammer things out one by one to see whats happening

THNKS

>>>>GOOO TO LAST POSTS PLEASE

BUMP FOR REAL TECHS

cmon 27 no bumps

the trouble shooting will start today so honda pros let me know what else i can try

n*werk

Timing.. Do the basic first and go from there

that 100 bucks for trouble shooting.. U can paypal me the money later .. Lol

trevek10

i also would like to add that i have three plugs that had no place to go from the harness EX harness if this helps i will also try and post pics of the plugs.. and one other thing to add someone once said that if i put my hand over the TB and it dies this means there is no vacum leak? true? cause i put my hand and it died will a bad o2 sensor cause the ecu to run limp and cause the car to run like this?

trevek10

well i dont have paypal account ( ? i think might have set up one while ago) put i will be sending cash expect it in the mail

trevek10

problem still there guys

you check you timing and all your grounds are good. just a couple ideas. also I would start checking hoses and make sure your coolant is full and no air bubbles.

ok pulled the O2 sensor what a pain that is when everything is in but i think this could be the reason why O2 sensor code comes back considering how black it is... these are all universal correct I pulled the one of d series to compare thinking of putting it in its place

trevek10

sry about the mac book pics kinda crappy lighting kinda hard to see but you get the idea one on right is D series// one on left is off JDM b18c

(don't know why i didn't change with motor out considering everyone gets this code)

trevek10

well changed the o2 sensor and put the one from my d16y7 in and still throw that code ... guess i missed that i was throwing code 5 which is map and i changed the IAC and the MAp plug and that code went away put still have idle problem and code 1// gonna do valve adjustment tomorrow as well as some other things///

any more suggestions?

Are you sure its code 1 and not 10? They are easy to get mixed up.

trevek10

well im pritty sure it only blinks once and then goes away then comes back on once soooo im gonna say one and not ten

trevek10

this plug has no place

trevek10

and this one the plugs look the same but slightly dif wire color

trevek10

and this one seems to come under the the Int mani

trevek10

anyone know what these plugs are for // do i need them ?? this is from a 99 ex wire harness going on GSR motor just in case you didnt read first post

(sry for huge pictures from photo bucket have to figure out how to make smaller)

speedooo

Some of this is common sense...

o2 sensors are in the exhaust...yes they're interchangeable. its black because it isnt registering and youre running rich.

google ffsquad pinout, find out what sensors those color wires go to.

if you put your hand over the tb and it dies that means your iacv isnt opening...theres your idle issue.

trevek10

well i got the running problem down but still throwing code one any suggestions ?

95civhb

what code is it? Your idle issue was prob the IACV...

trevek10

yea it was got that straightened out jsut have to bring the timing belt back a little bit to fix timing and lower the idle but I cant figure out why its still throwing code 1

SOHC my DOHC

Code 10 also only blinks once. Code 10 is one long blink, and code 1 is one short blink. Just throwing some ideas out there for you.

trevek10

ill look at that too what is code 10 ???

SOHC my DOHC

Intake air temperature sensor.
