D16Y4 idle problems + shaking and surging
hi, ive just put a d16y4 into my 95 eg to replace the ****ed d15b7 in it. ever since we got it running, the idle has been really off, really low to the point of stalling. ive noticed that the engine when running, shakes a hell of a lot.
when driving, steady acceleration makes the car surge, and theres a huge lack of power, it feels like somethings holding the engine back. a few times, when ive put my foot down in 5th around 100, theres the lack of acceleration and power, and then the engine light comes on.
and now its just running like shit, and has started misfiring, and sounding like an old truck.
any ideas on what could be happening?
ive just replaced o-rings and cushions on injectors, theres a new timing belt, and a whole new distributor on it.
Thanks!

Are you using the stock D15B7 ECU?
-
yes we're still using the d15b7 ecu
-
First off get a proper ECU that is tuned for the D16Y4
PM ECU-MAN he should be able to fix you up

I agree with dorikin.
Failing that, inspect your spark plugs first, and if those both fail then look at your idle-controlling factors (idle screw, IACV, FITV, TPS sensor, throttle cable etc).
Keep us updated.

Have sent the pm to ECU-MAN and awaiting a reply still haven't had a chance to drive it since replacing the cushions and o rings because it just seems to not want to rev, it will get to like 1500 and not rev much further and run like absolute crap when you lift the bonnet it seems way hotter under there then it should but the temp reads normal operating, I've be doing some research and I think it might be the cat converter does it sounds like it to you guys?
-
could try running without the cat to see if there's any difference
-
i cant see how it could be the cat , i would definitely try the right ecu first.
-
When ecu man responded he said that he has never heard of someone doing it and doesn't know if it was safe or not but to try and get a obdI ecu for a d16 non vtec only problem is that there isn't any in Australia, and another guy that has done the same swap said it was plug and play. the car did run fine at first well had a vacuum leak, but after a while just started to get sluggish then just wouldn't rev past roughly 1500 and the car on idle tends to drop revs a lot and when you move the accelerator it seems to continue with its fit then start to rev higher again
-
My car did something similar when my o2 wire was grounding on something, maybe have a look at that
-
Which timing belt did you use? Are you using a stock cam gear? I would check mechanical timing. Is the oil pressure sensor plugged in? Are you using the stock throttle body?
