Ok I did a B20B swap into my ek hatch and their is a code being thrown out from the ecu Code thread it says its the Fuel Supply System. I was wondering if anyone one else encountered this. This would pop out when i would cruise on 3rd around 4k and same for 4th gear. Right now the B20 is running on a Obd1 P75 with a Step Down Harness The car runs Strong but sometimes as im slowing down when it hits around 3500k - 3 k it would like bog or slow down. And sometimes when I Accelerate to 3500k any suggestion on what this would be??? I thought it was the O2 sensor i replaced it with the other one i had and nothing. And recently the check engine would pop on when I warm up the car.

Recently I got an External Coil (Msd SS coil) and Pro Cap. But the Problem was occuring before this.

This is everything thats on the car

B20B
Ls OBD2 Intake Mani
B16 Headers
O2 Sensors Wired Both O2 sensors Together so it can work as one
Skunk 2 Step Down Harness
OBD1 ls ECU

 

Does any one think if i seperate the O2 Sensors that might be the problem???

 

anyone??? i searched H-T and nothing so yea I Need help

 

Today i was at a light and i was Idling at around 100 k then all of a sudden it turned off. Then after awhile it would idle around 1200k and go down to like 100 K then back up to 1200K then back down to 100. What can this be?????

 

anyone??????

 

bump come one ppl no one helps me on ht ??????

 

BuMpppppp help please i cant read the code even with a OBDII scanner cuz the ECU is Obd1 and the car is OBDII

 

bump no one can help me?????

 

bump. help the guy out.

 

thanks 90dakid BUmp!!!

 

does anyone think im not getting enough Fuel (im getting a FPR by this week i ordered it a week ago) Distributor timing??? (since i have a MSD external coil???? with a pro blaster cap and Rotor???) ANYONE!! please!!! dont want to hurt my motor!!

 

sorry to bother but what kinda mount, harness you used for this swap? i got a 98 civic cx soon to be swapp a b20b. bump

 

check that your injectors are clean and not blocked up or dirty
maybe look into a b series vtec (gsr/b16/itr) fuel pump (?)
...dunno

 

well i work for Firestone and early in the swap i did a FUel System Cleaner to my car so i dont think it that but i will try it and clean up the injectors again. and im using a DX harness juss needed to modify the Idle control and thats it. I really think with the FPR i might help but i need juss a little bit more info on this CEL and if anyone has had it .

 

Was wondering if the Injectors spray in an ORDER cuz i connected the longest Injector wire to the one closest to the tranny and shorts to the one closest to the Timing Belt (Dx Engine Harness) And also i was reading the FAQ guide on doing a B20 Swap in a EK The owner had a ITR Fuel Pressure Regulator how many LBS of Fuel would that push????? at idle and WOT THANK HT please help!!

 

well i changed my Dizzy and well nothing it doesnt bog as much any more but it bogs around 4k around their not at 2500 anymore any suggestions

 

hey did that b20 was plug n play what head are u using is it a stock b20 block

 

yea everything is stock and not really something u have to change Ivac , intake runner sensor, Ecu pins etc etc

 

hey were u at i got a homie that maybe can help u i am in la i pm u check
