I have problem with my car pickup and response on petrol and on CNG the rpm stays at 2000 or 0000 when i leave the race pedal(so i disconnected the cng wiring beacuse even after servicing the cng kit issue remain same.
few months ago i changed fuel filter,fuel pump new and used tuning,plugs,throttle body serviced many times, tappet done but it gave the same problem of rpm as i told above,plugs changed every mechanic did his science.issue permanently resolves for few days but come back again. car is heavy and acceleration is slow. one more thing i remember is that when i disconnect the terminal of battery and then put on again car runs lot better with rpm remaining at 1500 for sometime as soon rpm starts t ome to 900 the issue of pickup comes again. today i drive with taking i80 sensor out and car is running fine again. also the normal pick is very heavy most of the times and on AC more heavier but during the AC trippping time car becomes bullet(this tripping pik is great even better than without AC pick). Also the pedal of the car becomes heavy when pick is bad or heavy and when i took air sesnor of the pedal gets soft and pick is good also when i put on terminals of battery back on but only for few minutes.\
Manual civic with cng installed but original injectors popped into the injine
