Symptoms: Slight intermittent missing at low RPM when throttle is pressed more than 1/4. Seems to have delayed throttle response. Once RPM is above 3k then its fast.
Valve Clearance Adjusted to specs.
Fuel Pressure at 43 Psi at Idle and 50 Psi otherwise
Injector Cleaned with Ultrasonic Bath on ANSU machine.
More than Half Air Intake is blocked because of CNG i wish there was another way
Questions:
1. Spark Plugs
Most Important Concern is why my spark plugs are like this.... in two colors. Cant read if its rich or normal. For sure fuel here is not good. I goto Caltex.
I Inspected the timing dis-color it was almost at 90 degrees
The Air/Fuel Ratio is not a constant ring though.
2, Distributor
Few months back the terminals of distributor cap had some grove but not that bad but i scratched them a little however when i got to junkyard to ask for an other cap they said its just fine. Have a look and tell should i replace. I wonder if there is any availability of new caps. If there are they would be chinese.
