Brother many thanks for reply actually i was trying to say that IACV stucks at 2000 RPM I have serviced IACV with local mechanic and it was fine but after one month I have same problem now was RPM stuck at 2000 at idel and it goes down when I press cluth or change gear.
Should I change neotek advancer with lendirenzo and change the venturi to burner type?
Second problem is that on CNG the car stalls at low speeds at RPM goes as low as 200 and engine stops at A/C it all starts recently when i installed neotek advancer black one and now the cng consumption is reduced from 120km to 80km.
I have heard that RPM drop problem on civic is due to incorrect advancer.
The TPS cllaibraiton threead is my favorite but the problem is that I have no clue how to do it or form where in karachi i can get it done at a good place I will viist tatiq road tomorrow.
So if I change the TB is it a good decision at ragazine line plazza quoted me 5000 with installaton is it resonable?
