Why does my motor bog when it hits a constant speed?
Hey all
1999 Civic DX
1998 D16Y8
1998 EJ8 tranny
The motor pulls fine and it runs decent. I had it with a Y7 TB w/ Z6 rotor and it idled at ~1600 and fluctuated. It was really annoying, but it drove fine. I installed a Y8 TB and ever since then, it idled fine (~1000) but when im driving and say Im going a steady 40MPH, it starts bogging and sputtering. RPM's don't fluctuate, it just sputters and the exhaust sounds like its spitting. It accelerates fine and revs like its supposed to.
Any tips on that?
CELs I have:
-IACV
-Second o2 sensor
-ECU malfunction (ECU works fine btw)

I took my Y8 TB to get the TPS grinded off and I installed a new Blox TPS and it still feels the same. So that marks off the TPS as a problem.
