KA24E Hesitation

[DJPimpFlex]

Sputters and dies. Not a problem when cold but is almost undriveable when warm. Poor gas mileage and popping under deceleration. List of things replaced:

-o2 sensor
-thermostat
-maf
-tps
-Fuel Filter
-Spark Plugs
-cap and rotor


Next logical step is fuel pump. ECU isn't throwing any codes. Anyone have any other ideas?

[lbogkush]

yup gotta be fuel or air leaks?

[KiLLeR2001]

Gas tank venting properly? Gas cap good? Fuel check valve working?

[DJPimpFlex]

Anyone else with any ideas? I'm going to check for vacuum leaks tonight.

Sounds like the fuel pump is going out

[rcdad123]

sounds like its temperature related issue. try a new coolant temp sensor.

[DJPimpFlex]

Good call. I'll get that tomorrow.

Winner winner... Water temp sensor. Runs like a dream.
