I suggest you figure out what the problem is before you start running out and buying parts.

Have you tested the fuel pressure to see what it is?

What ECU are you running?
Any CEL codes?

 

i am running the obd0 ecu.....i checked the fuel pressure and it is where it needs 2 b

 

check your IAT(intake air temp) sensor and then check your o2 sensor

 

I had a friend that had that same situation he had a vacumm leak somewhere and after he fixxed it. now it it's back to normal.

 

which v-lines do i look for..?

 

My civic ran real rich, but I wasn't going thru spark plugs like you though. I converted my b16 over to obd1 it it solved all my problems.

 

Make sure you're getting spark to your spark plugs first. Than double check wiring.

 

check em all. remove unneccary ones.

 

do u have both o2 sensors hooked up and in the right order

 

when i did the b16 swaP Everything(o2's) were hooked up right
