CAT converter was not in the Civic untill Reborn.
No O2 sensor either.
Check if your distributor, wires and coil are giving enough current to all cylinders for proper spark.
no check engine light in the car. the idle speed is stable. i don't have rpm in the meter so don't know exactly what the idle is. valve clearance is ok got them checked from mechanic. i don't know how to get fuel pressure measured.
a manual test was done by a mechanic which turned out ok as per the mechanic
Probably your car does not have O2 so i guess
engine and ecu is original but it ran on cng for many years. its been running on petrol for the past 6 months now. where and how to get points 1 2 and 4 done from in karachi?
@xulfiqar may know and he can also help.
The local mechanic will pull out your fuel pump and could do the famous water tub test in which the fuel pump will work like a water fountain.
And which is useless........ mechanics did on my car and said your fuel pump is a toast where as when i checked In Rail fuel pressure it was 38 I blocked return line it went above 48 so for sure that fountain trick is not worth it get it done with fuel gauge
Sir definitely when u blocked return line the pressure will skyrocket but if the pump is not making a pressure at all or there are gaps in flow it will be revealed in the water fountain test.
Nahi dost....... what my test concluded that Fuel Pump did not had problems creating the pressure it was Fuel Pump Regulator. You cant tell if pressure is within specific range with so called water fountain test. In cars with FPR on Rail there are two pressure specifications Idle and WOT...........
Does your car has catalytic convertor? A choked catalytic convertor plays hell with fuel consumption, however, another indication is that the engine appears powerless.
Local pkdm 98 didnt have catalytic converter
