have a d16y8 in a 92 civic hb ... when i take off either fast or slow the car will sputter like if your gassing the pedal in and out only sometimes though... i have new clutch new throughout bearing... d16y8 ex tranny if it matters.. have tried different ecu's... idk where to start.. what can cause this sputter? and once again it doesnt happen in specific rpm's or specific gears...

HondaPartsHero

Any check engine lights? What ECU's did you try? Has it done it since you swapped it or just recently? Any regular maintenance done (plugs, wires, etc)? What distributor are you using?

im using my b7 dizzy because i kept the motor obd1 and all regular maintenance has been done and it has done it since swapped in about # weeks ago

Does it sputter at idle too? or only during acceleration or while taking off? Sounds like you have air in the cooling system or sensors needs some cleaning

JENNY_EG6

and you do know there's a difference between a vtec and non vtec dizzy right?

94EG8

Y7 and Y8 distributors are identical, right down to the part number. D15B7 is exactly the same as well except for the OBD1 plugs.

JENNY_EG6

I know they have the same part #,and I know it'll make the car run. I owned one before and there's a difference using a Vtec and a Non-V dizzy. In fact, you can try one yourself put a non-v dizzy on your car and run it.... Anyways... I wouldn't put a chicken's head on a duck... as well as a dizzy I'd use the dizzy that the motor came with...

id say you have air in your system, had the same problem in a 91 with a mini me setup

94EG8

Again theres no difference in this case, none. I've pulled apart and built more hybrid distributors than probably any other person on H-T. Z6/Z1/D15B Vtec distributors have a different mounting flange and possibly slightly different timing. But Y7/Y8 are 100% identical, again right down to the part number which you've already admitted, if the part number is the same, they're the same, thats whole point of the part number. D15B7 is different only in terms of having OBD1 plugs, its internally identical physically and electrically to a Y7/Y8 distributor. The whole reason you run a D15B7 distributor in this case because it both bolts up and plugs in.

This is happening to my buddys EG hatch z6 and doesn't have vtec wired up. Wondering what the dealio is.

qpzm12

is it maybe because vtec isnt wired ??? and yeah ive been told that there is a difference in the dizzys but it shouldnt matter...??? it bolts up and runs what negatives can a non v dizzy so on a vtec motor??? and it only sputters when i try taking off like while accelerating... whats it mean if i have air in the system??

94EG8

Again, I don't know how many times I have to say this, in this case there is no difference in distributors. If it was a Z6/Z1/D15B Vtec it would matter because the mounting flange is a little different and you can't properly set the ignition timing, in your case no difference at all. If vtec isn't wored you'll throw a CEL for vtec solenoid and vtec pressure switch. Btw, what ECU? If its a P28 you'll have to chip it to get to run right, timing is different between a Y8 and Z6.

94EG8 i dont think they understand.... lol

94EG8

Which part did you want clarified?

qpzm12

haha it doesnt throw a code at me for not having vtec wired because i do not have a vtec wiring harness

94EG8

If vtec isn't hooked up it should be throwing vtec codes.

qpzm12

if vtec isnt hooked up and you have a non vtec wiring harness it will throw no codes it will show as if you have a non vtec motor

94EG8

This does not work the way you think it does. Vtec ECU will look for vtec solenoid (and in most cases a vtec pressure switch) period, it doesn't matter what you have for a harness, if vtec isn't hooked up and you aren't getting vtec codes you either don't have a vtec ECU or its been chipped with a non vtec program. What ECU are you running?

qpzm12

how is my car going to know if it has a vtec motor if it has a non vtec ecu or no vtec harnesS??? hav p28 for when i do wire vtec

mr2passat801

If you have an non vtec ecu and harness, and the motor is vtec and its not wired up, it will not throw a code. But if you have a vtec ecu and a non wiring harness, it will throw a code. Or if you have a vtec ecu and harness and its just not plugged in for whatever reason, it will throw a code...



Also, your sputtering could be tons of things. Plugged fuel filter. Going bad fuel pump/regulator. misfire! detonation. Many many things. And since I am assuming you dont have the knowledge or tools to check all this stuff. You might just have to borrow and try a bunch of different parts.
