The engine i bought, has been sitting surran wrapped and covered in 2 tarps, i saw it with my own eyes. And my sisters 4 year BF sold it to me. So its been sitting correctly i guess, but i think its sat for 3-7 years. ill come back to that^

So as some of you know i was having a power problem in my b16sir II so i did a compression test and the results were pretty low for a b16 especially with cams. So i decided to do a swap. Heres the info: Previous motor used the original eg cx harness and wired. It has a chipped p28ecu no nock sensor or o2 sensor, New swap obd1 gsr harness same ecu, Only thing i dont have is the intake piping sensor wired up, and there is no sensor on the intake next to the fuel rail on the top of the manifold. im not sure if this has to do with my problem, OH i almost forgot to say what my problem was.... It starts and runs if you give it gas, the check engine light is of course on.. the timing on the cams are perfect and the timing on the ignition is perfect, but it wont stay running and it shakes. I used my tethiscope to listen for any unusual sounds and it all sounds good under the hood. i did a compression test and in order from 1-4 i got 190, 175, 135, 201 i believe cylinder 3 the pistons are just stuck from sitting for so long, so if i run it long enough the compressions should go up if thats the prob. now this engine was guaranteed to run because when my sisters bf bought it from some jdm motor import company the had a video of the compression and paper work guaranteeing it for a year.
So from the sounds of the engine and what it does im thinking its wiring, ecu, or a sensor not working or wired up<. I have a lot of time and money invested in this engine and i really hope there is a simple solution. Any info will be great, also to clear things up all wires cap rotor plugs belts blah blah its all new..

Thanks HT.

so just for the hell of it, i hooked up another chipped p28 ecu i had and it started sounded crappy and shaky still and then i aher a ssssssssss and smoke coming from the ecu....... im starting to thing its an electrical issue.

worx

you said you have a cel. have you pulled the codes?

Etzim

I have not pulled codes.

bryan24207

find a friend with an iphone and an obd2 cord for it. its help me and alot of my friends

Ground the service connector and check your codes

Etzim

So i can decipher the codes this way? https://honda-tech.com/forums/honda-civic-del-sol-1992-2000-1/how-pull-cel-d4-srs-abs-codes-code-lists-1901557/ I never knew of that :O at school we just use a scan tool.. but my car is not operational, its still in pieces. No shift linkage in yet no exhaust "running a down pipe" and no axles. waiting tell i get the engine running perfect before i spend all the time putting the axles and stuff back in. I really wanna get some codes pulled tonight but its kinda late right now. I will check tomorrow and see what i can come up with. Hopefully its nothing serious and i will be able to figure it out.

Oh and Thanks for giving me the idea of searching "How To Retrieve CEL Codes honda" I honestly was stuck and didnt know what to do from where i was at.

Yes and thanks for searching for that instead of asking..check your codes and let us know what they are

I mean it might just be me but I think you are starting a little to big; running the code is fine but if it's wiring, a lot of times the code isn't going to pinpoint the issue. Always start small and work to bigger things, I had a problem with my fuel system when I rebuilt my B16 on my 2000 Si. Because I started small and check all fuses and relays and continuity to the fuel pump, I saved myself a lot of time and money. Let me know what code you throw.

Oh and if you could maybe create a video of the motor running and what noises its making it may help us understand a little more. Good luck.

Pulling the codes will help you adress the issues it's having.

Etzim

well it had a b16 swap in it before it ran fine just, vtec for example would pause and get stuck at a certain rpm, or it took a while to start it, i found out the compression was way low on that engine so i swapped it. everything else worked fine. just some of the wiring in my car is ghetto and i think i will fix that before i turn the key again. I will also upload another video if i can get it running.
But after i fix the ghetto wiring i will pull the codes and post them up with the video so you guys can help me

I really appreciate all the info/help thanks guys. ill work on that video and wiring after i get home from school.

Steezer

Show us a new video.

hmonguy918

sounds like a valve job to me. had the same problem in my b16a2 but it could be different for u since the wiring and everything

canadaek

injectors don't like to sit for long periods of time try swapping the injectors from your other motor in and put a very small amount of oil in the cly and roll the motor over with the plugs out then recheck compression

Etzim

Heres what i got
10 IAT - intake air temperature sensor
looks like i will be wiring that up
And
14 IAC (EACV) - idle air control valve
I will have to look into that one, not sure if i put the wrong plug in it? or didnt connect the hoses idk..


and im uploading a video for those of you who are interested in hearing it, and deciphering the codes yourself.

Etzim

ok so i had the wrong plug plugged into the iac, plugged the correct one in and WOW what a difference, im working on wiring the iat up. I'm sure that would also make a differernce. Im still concerned about the compression. But it could just be a valve was stuck from sitting for so long idk. will seafoam it or something. its kinda shaky too any ideas? silicone the mounts? what silicone?

Did you reset the ecu?did the code go away?

Etzim

Ok all codes are gone no check engine light, except it runs weird after i hooked up the IAT. like it barely idles it sounds cammed out yo. it idle bumps too. i wired it in without reseting the ecu tho so haha thats probably why.

Etzim

ok wait im still getting the code for the iat, im not sure where the other wire goes... im thinking D/22 i have the red/yellow wired already.. just not the other one i cant find where to put it

Etzim

ok i see, so it does go in D22, theres like 5 other wires that splice into it. I just need to splice the sensor wire. Easy deal, Thank you everyone for your help. the cel codes helped narrow stuff down a lot.

They always do that's what their there for

Etzim

one last thing. on jack stands the wheels spin and i cant stop them in neutral... uhhhh

raverx3m

iTrader: (1)

wheel spin is normal cuz the clutch is still engaged in neutral so the tranny innards spin as well they just not in gear.

Etzim

yeah, its got like hardly any power with an open header but my cat should be in the mail tomorrow

Etzim

Ok got the cat on. This car hauls *** Vtec kicks in very smoothly and it feels like im running a 5psi turbo, im telling yah 60psi in the cylinders makes a big difference. another problem, if anyone can help, when i turn my wheels go clunk clunk clunk. Sounds like my axles, but why would it do that?
