cold engine bogging/sputtering? jdm b16a in EK
 

ok I got a 97 ek hatch with a jdm b16a, wired with a 96-98 automatic ex harness. everything is wired correctly to my knowledge, and the plugs/wires,dist., fuel filter, tps, IACV, and injectors have all been changed to try and fix this problem.

When ever the car is first started, say in the morning, or after its been sitting and the engine has cooled off. You start it and try to drive, and it like runs very rich/bogs and will even backfire. It barely moves, unless you kinda push the gas peddle in and out it'll pick up if you are heavy on it and go. This continues until it reaches the normal temp.

Then once it warms up it drives amazing... for about 30 mins. Then it just looses a ton of power out of nowhere, doesn't sputter or anything, just seems to loose a shitload of power, mostly midrange, the vtec end is still strong but no where near as good as before.

Could it be the main relay? Should I get a 5spd harness? I'm pretty much out of ideas here... any help is appreciated. Thanks in advance.

Oh and I'm shooting no codes whatsoever. ECU is a phareable chipped p28.

interesting, I have a phearable chip p30 and while I am still finishing up my swap I noticed that at 1500 rpm I have to give it a lot of gas to get it up and over, Plus im not getting much power at 5k rpm. I'm replacing my IACV now because that was bad, ill let you know if I still have problems, let me know what happens with you.

So your vehicle is throwing no codes ?

Out of several hundred customers I have yet to have one complain about the symptoms you are having.

I would be more then happy to have you mail your ecu in for inspection.

Thanks,

Your vehicle will drive awkward with a messed up iacv. https://honda-tech.com/forums/images...s/emsmilep.gif

Hey John,
Definitely not trying to down your work. You have been very professional and quick about everything. I don't want anybody thinking that I have diagnossed the symptoms to a bad chip job. I still need to fix the iacv and get the car tuned. I haven't driven my swap yet so I can't say anything negative about you or phearable, and I don't plan to. Thanks for the support, ill let you know if I need it https://honda-tech.com/forums/images...es/emsmile.gif

no man, its nothing to do with the ecu, the old stock P30 I had did it too. The ecu is shooting no codes at all now. My search goes on to figure whats wrong with it... next up is try my friends main relay (doing that today) and then get a 5spd harness and see if that helps... I did the IACV plug mod required to use the auto harness which took care of the code 14, but still no luck on the bogging...
