Brother i am facing a little lag in the race of my car let suppose if a press pedal it takes 0.5 or 1 second to respond and RPM is also not stable. after pressing pedal car takes a little lag to respond back.
Things done so far to get this resolved..
1. Fuel injectors cleaning
2. Throttle body service
3. Fuel pump change
4. Ignition coil change
5. Plugs change
6.Plug wires change
7. Distributor cleaning
8. Map sensor change
9.Proper tunning
10. compression test
11. complete wiring test through meter
All of the above things are done from some of the famous mechanics in islamabad/rawalpindi but still the problem is there. What i truly believe now there is some sensor that is faulty and mechanics are not able to find that manually.
