Car 1997 Civic with a B18B with a P75 OBD2 ECU. engine is stock but I cant get it to run right. Please see the video I posted onto youtube. Also the sputtering also happens when going down the road and trying to cruse at a steady speed. at high RPMs (5000+) it does cut out and revs normal and it idles normally. I cant find a vacuum leak and the fuel filter is new fuel pressure is at 48psi, timing is spot on, spark plugs and wires are good, what else can i check?

The CEL code is P0117 ECT circuit voltage low. And I also can not figure out why i get that code. I have 5 volts to the sensor and good ground. Continuity good from plug to ECU (connector D2)

 

Did you try cleaning the IACV?

 

Yes I have and I also swapped it from one of my other engines

 

Anyone???
