ok i finally got my b16 in and running it is in a 97 civic and it is running really rough the other problem i am having is it will not stay on unless i hold the gas petal down is there anything i can check please let me know thanks guys..
the civic is a 97 lx and the ecu is a chipped p28 if that is needed thanks guys

man no one can help me out?

 

have you checked timing, is it throwing any cel's? is compression good, are you getting plenty of flow from all of the fuel injectors? Spark on all cyl.?

 

Is your IAC plugged up?

 

well compression is good i have flow how can i check if the injectors are good? i am getting spark from all cylinders my timing is perfect not eve off by a tooth. the IAC is plugged it now the check engine light is on but i don't know how to do the CEL check i see the green plug but what do i do something about putting a pin in there or something can someone tell me how to do that thanks

 

what is your timing at?? should be 16 degrees before tdc

 

on the green plug you will see two connectors, a 3-wire and a 2-wire. Pull the 2-wire plug out of the green holder and place a paperclip or speakerwire or whatever just as long as the two wires jumped. Turn key into on position, CEL blinks, count, and get code.

 

yeah your talking about the dizzy timing correct? yes it is on or just about 16 degrees. so i don't know i will check that cel tomorrow and see what it says

 

o yeah i forgot to ask can i do it being that my civic is obd2a and my ecu is obd1? will it bling for me?

 

to check the the cel you have to put somthing in it like billyhoe said but when you turn your key on dont start it just turn the key on and the light will blink once but after that one blink long blinks count as 10 and short blinks are 1 i just thought i would clear that up a lil bit

 

hey thanks alot man i needed to know that but i was still wondering about if i can do it on my obd2 car because i am using an obd1 ecu it should still work right? or do i need to get one of those code readers? thanks guys

 

yep it depends on your ECU

 

chipped p28 is the ecu i am running

 

hey man i have a p-28 chiped in my 99ex with a ls vtec using a 99 head from my b16a2// it all works fine the only i could think is if it is not timing then maybe u have a vaccum leak or a bad fuel regulator that is no keeping enough fuel.. it happen to a friend of mine,, maybe that will help.. but far as the ecu it works the same just dose not read intake sensor or second o2.. or the crank angle sensor,, plus to me it makes it run alot better i have the mugen chip in mine,,

 

guess he does'nt want his car fixed.. takes all of what 5 min to check the cel

 

because i didn't know i could do that on my obd2 car now i know i am going to do it today thanks for you help tho

 

ok i did the cel test and i am getting only one code it is a code 14 let me just make sure i got this right it is one long light then four little blinks so that is a 14 IAC (EACV) - idle air control valve correct? now how do i go about trouble shooting this?

 

the iac valve is on the back of the intake manifold. unplug the wires coming from it and see how it runs. you may have to mess with ur idle screw to keep the motor from stalling. your most likely going to have to replace it. about $200 from honda. you can drive with it unpluged, if that makes it any easier, but your going to need to replace it soon since its getting cold out. until then u might want to sit with ur foot on the gas for a minute to warm it up.

one thing that u might want to check though, my ecu was throwing the same code (21 on my ecu) and i replaced the iac valve and it didn't solve the problem. my ecu was bad. if u can, try running a different ecu and see if you still have the problem. good luck

 

kool thanks alot i am going to try that my boy has a chipped p30 and see if i get the same code along with the knock sensor since i don't have that wired on mine because i don't need it with the p28. but that helps me with one problem now the other problem..i will make a new post for it...thanks guys

 

i mentioned my code for the IAC valve was 21, that was with a p30. hope that saves some time

...i think

 

ok i just came accross something i have an obd2a car that was non vtec and i was shown the ffsquad website
http://technet.ff-squad.com/
on the wiring for the IACV now i did the two wire plug and i thought that with the obd2a(car) to obd(ecu) convertion kit i didn't have to do the whole moving of the wire does this make any sense or was my information wrong about not having to move the wire? please let me know thanks

 

anybody know??
