Occasional p300 p1316.......What gauges from my Ultra Gauge would be useful in determining area of malfunction.?.......fuel trim/ fuel press/maf sensor/bank oxygen sensors/egr flow/relative throttle position% or what other guage would you look at?

 

Here are the Jaguar DTC codes. Be sure the Ultra Gauge is set for 9141.

 

You are getting some random misfires. Check your spark plugs and make sure there is no oil or water in the spark plug wells.

Also check your fuel pressure at the schrader valve on the fuel rail. You cannot read fuel pressure electronically on your car.

 

MRomanik and WhiteXKR.......Thanks for you'r input!
