I have a 93 Civic Couep w/ a JDM B16A OBD1 and Im running into some problems.

When Im driving about 1/8-1/4 throttle my car tends to act like its struggling and it jumps forward and the tach bouces... Does anybody know what this could be from. This also happens when I just floor it. Also, my needles on my spedometer have been bouncing all over the place? Could my motor be going out??? Please help.....

 

any CEL's?

 

What ecu are you running? mine did the same on jun ecu, I think.

 

You know belive it or not my buddy had a 96 civic coupe and he had the same motor swap his gauges we're doiung the same thing he siad sumthing about there being an actual hole in his gauge cluster that made it do that...dont know if thatll help

 

my cousin had that problem a while ago and it turned out to be his cat converter. Might wanna check that.

 

i heard that it could be my cat... im running a mugen chippped p28 with only a stock b16 and ITR cams with a intake... no exhaust... still stock 93 DX exhaust...

could that be the problem??

also, since my ecu is running fuel rich would i be able to change that using a VAFC?
