I just got finished swapping a si intake ,distributor , exc... onto my d15 motor crunk up first try but try to give it gas and it sputters a little then revs up ,but I took it to the road anyway start out in 1st picks up speed then surges to a stop keeps on doing this with peddle on the floor after about 3 to 4 times mabey more check engin light comes on when it comes on it stops surging and rus pretty good switch the key off then back on light gose out and starts all over with the surging I really need some help just got finished doing swap about 20min. ago and cant figur this out ..thanks

 

I'm having a hard time understanding what you mean but did you reuse your IM gasket? I know people have run into a lot of problems reusing one when it should of been replaced. Did you set the timing correctly?

 

When you change things that are going to allow more or less fuel and air in you need to reset your ECU. This very well might not be your only problem but it does cause the RPMs to dip when you press the gas. Pull your hazard fuse for 20 seconds when the car is off, then put your hazard fuse back in, and allow the car to idle for at least 10 minutes so it adjust to the changes you did.

 

what do you mean IM gasket?To be more spacific when you give it gas the motor starts to rev up and then its like you switched the key off for a second and switched it back on,its like you shut the fuel off then cut it back on.it only happens when you drive it,when it idles it hesitates a little then revs up.

 

IM = Intake Manifold gasket = gasket

 

so exactly what all did you switch over?

 

I did reuse the IM gasket.

 

yeah, what exactly did u change over?? are u using the PM6 ecu or you still have the PM5? if so thats your problem. or did u do the mpfi conversion or did u just throw on the manifold?? idk, thats not probable, but just making sure.
To change from dpfi to mpfi, you need the int. manifold, distributor, injector resistor box, and you need to rewire for four injectors.
my $0.02. i hope you get it fixed soon. payce

I changed intake distributor added resistor box I used an integra ecu should work fine cause you use it on zc swap or use pm6 its still a mpfi ecu I did every thing by the book wireing every thing its just a small problem that prabably has a quick fix I was just curious if anyone else has had this problem thats done this swap and about resetting ecu shouldnt it be reset cause I had the battery dissconected the hole time I did the swap

 

I think I would ask Josh Burgans. He seems to know everything about EF civics.

 

Check the injectors....i had some bad injectors and it made it ride crappy...find out what code the ecu spits also...check the throttle cable too

 

hey,josh its me jeremy,from undefined.
