My Honda Civic 2005 Vti was giving me RPM Stability issue on Petrol as well as CNG. I tuned up my car, cleaned Throttle Body (which was filled with carbon), Set Tappits, Cleaned coils and aprk plugs, etc. After all this, she is just like a killer on the road. But still same race issue persists. I think either it needs to be change TPS Sensor or Throttle Body + TPS both. Kindly suggest me Individual prices for both and where can I get these from Karachi.
Sir i am facing the same issue that u have discussed in this forum, my car is totally driven on petrol and since last two days i m having this Rpm issue, people(Mechanics) said that its something with the injectors, i must get the Injector cleaner in my car tank with Hi-octane fuel mixed with the normal one. I am about to get it done tomorrow but just read your thread , i want to know what solved your problem ? or can i call on the number u have given in ?
