My first attempt at DIY with a Honda was an engine swap. I have a 97 Civic Non-VTEC DX 5MT (D16y7) and swapped the engine from a HRV automatic (D16W1). I used the Civic's manifolds (intake/exhaust), the accessories and wiring. Car runs well with the exception of a high idle. Initially, the car would surge at idle. I replaced the IAVC sensor and the engine stopped surging. I added a new TPS sensor and adjusted the throttle cable. Idle is still high. Timing was next. I verified the cam and crank position per the timing marks. I could not get the timing marks on the balancer to line up whether I advanced or retarded timing (maybe the two engines have balancers with different timing marks). Finally, I bled the cooling system of air. The high idle is still present, just not as high as it was previously.
P.S.- I inserted a paperclip into the connection underneath the dash on the passenger side while setting timing. Nothing changed with the exception of my speedometer stopped working once I put the car back together. I verified the fuse in position #15. The fuse is good; however it is 20 vice 7.5 amp. Any help with these issues would greatly be appreciated.
