B16a break up and hesitation
 

Hey guys, I’ve got a b16a swapped ek, I’ve got a video of it but it’s to big to upload, if there is a way to pm it or send it on fb or even a text. Please just let me know. Anyways, it’s kind of hard to explain exactly what it’s doing. I’ve put a lot of new parts on it and NOTHING IS FIXING IT!

Upload to YouTube and post the link. Sometimes throwing parts at it is not the solution. What troubleshooting have you done?

Here is the link to my video on YouTube. It has a new dizzy, map sensor, plugs and plug wires. Timing is on point, has good fuel pressure. I’m getting engine codes p1359, p0505, p0325, p0133 and p1457 it has major break downs in performance when it’s underload. Seems to rev fine when in neutral. thanks guys

Re: B16a break up and hesitation
 

LIkely harness problems and / or plugs plugged into the wrong sensors with all of those codes. With a swap (especially if you didn't do it personally), mis-wiring is common. Has this car ever run properly since you've had it?

Check sensor plugs by wire color. Ohm test the distributor sensors all the way back from the ECU end of the harness (unplug ECU and measure resistance through the wiring including the sensor). The CKP and P1359 is likely the root of the runnability problem; 1457 and 505 suggest swapping of the 2-wire plugs.

I did not do the swap myself, and if you ask me, whoever did the swap in this car left the engine bay a complete mess, since I’ve owned it (about 2 months) I have not had it running what I would say is 100% some days it seems better and then other days it acts crazy almost to the point where I can’t even drive it. Every time I think I got the problem or it’s fixed it goes heywire and proves me wrong haha. Like right now I’m idling at work and it keeps bogging down and shutting off on me every few minutes.

Bump

Re: B16a break up and hesitation
 

Also I’ve read a few other threads and on other forums, what do you think are the chances of this being an ecu issue? And another note to add to this, the previous owner said that he thought the car could possibly use a new ecu.

yeah id stop driving it hard, something is wrong.. swap the ecu if thats what youre thinking.

Re: B16a break up and hesitation
 

yeah I only took it up that high to demonstrate the issue.
