So , i've got a 1997 dx civic w/ a d16z6 (yeah lol weird i know) running a stock harness w/ an obd1-obd2a jumper harness and a p28 ecu.

At idle, when i floor it, the car jumps to maybe 1500rpm, falls slightly for about 2 seconds then revs freely to redline. All of this under full throttle. Accelerating from 0 is challenging sometimes, usually after idle when i haven't revved it up first, the car stutters and jumps until i even out on the throttle, or it gets a hold of itself (usually 1-2secs) and accelerates normally. After any prolonged amount of constant throttle, the car stutters and pauses before accelerating when i push on the gas.

I've tried 2 ecu's, a chipped P06 and now a stock p28 and it does it with both.

Am i dealing with sticky injectors or something?

any ideas would be helpful.

Perhaps it could be a fuel delivery problem. Have you changed your fuel filter?

my car did same deal it was distributor, borrow one from someone and test it

how did you connect your distributor?
z6 distributor has 2 plugs and obd2a engine harness have only one (for the distributor).
did you just do the swap?

wired it using a z6 harness

hmm thats actually a good start though! we did swap out the dizzy for a used one a buddy had... it def. could be having problems.

is this still a possibility if its running fine up in higher rpms and at any constant throttle?

i'll check the fuel filter too, but its pretty new so i doubt it.
