4G92 throttle body

[kayour]

Sounds like TB probs, do you feel any unusual just rev the car without driving? For example rpm meter goes ups and down a little bit even ur foot was holding still at 3k rpm?
Picture below no.1 is ignition coil. Coil faulty is unvisible outside only the worse i heard is getting melt

no la...thats not ignition coil
its distributor...or for 91/93/mivec..its called CAS [cam angle sensor]
the ignition coils r hanging at im...end of plug cable

Sorry... interupt a bit..
I am newbie also.

Any Sifu out there? Please help...
I change my mivec 4g92 auto (CJ4A) Throttle Body recently when my car have problem.
The mechanic told me the Throttle Body's sensor have problem and ecu cannot read but cannot just change the Throttle Body so just replace the Throttle Body to a new one... but with bigger bore size...
1) May I know what is the original Mivec 4g92 Auto Gen 2 Throttle Body bore size...?
2) If the Throttle Body change to bigger bore size will the fuel consumption up?

Image are the new Throttle Body with bigger bore size....
