Made a turn and drove between some buildings and I could hear a popping noise coming from the exhaust. Also there was a slight hesitation w/ a slight miss. Sounds like a gas engine when it's burning rotten gas or a faulty spark plug. Replaced the injectors last year and got about 40k on em, always ran a 2 mic fuel filter, and the last 10k, 2 cycle oil. I did start and drive off on a cold engine when the temps were cooler than 40 until the temp came up, then I drove a little harder. I'm thinking bad seats or guides, cause the older 24 valves crapped em out when drove cold. What's your guys comments?

 

 

what kind of boxes or programmers might you have? specifically timing wise?

 

timing or fuel supply

 

Only box I got is a Striker II and it's only a timing box.

 

MAy be too much timing ?

turn / take it off and see if the problem goes away

 

that's what i'm thinking too much low end timing. any fuel mods like an Air Dog? do you know what the rail pressure is at or the LP pressure?

 

Sorry, I meant pressure box. Running a FASS 95, no fuel or rail pressure gauge.

 

well if it is a pressure box then what about fuel pressure to the CP3 dropping or the rail pressure being too much or not enough?

any codes? even though the light may be off there might be some in the computer

 

burnt valve?
