VZ running sluggish

[Mick333]

Hey all,

Got a Vz ute Leo v6

Last few months have noticed it’s losing some of its power. Everytime I put my foot down the engine will jolt & shutter until it change’s into second or third. (Driving normal the car is great, only happens underload)

Replaced fuel pump, coils, sparks, new oil, new trans oil.

Have noticed when I disconnect the battery and let it drain the car will run fine for a day or two, then back to normal.

Any help would be great.

Thanks

Going to need to get live data from the car.
You need a scan tool or maybe diag app like dash command or torque to get some info.

Any warning lights on?

Get a throttle controller. Instant power
