diagnosis anyone

Gday all,

The Car: 98 xh ute 140000km 4l I6, pacemakers, 2.5 inch system, hi flow cat and muffler, crow stage 2, AU head, 10mm leads and a king dragon filter, auto.

The Prob: When i start the car at anytime and need to plant the foot within 2 minutes of starting the car it splutters and almost stalls then will suddenly take off. This has only recently started occurring along with a slightly rougher idle but suprisingly the car feels a tad more responsive when it is warm.

i thought it may be some timing issue????? would a dyno visit be of use?????? i don't have a vernier cam gear.

cheers lads

any advice would be well pleasing

Re: diagnosis anyone

The splutter then go sort of sounds like it is over fueling, then burning off as the revs rise.

Re: diagnosis anyone

Leaking injector?
Any smoke of any description?
Could it be the auto entering too high a gear?
When were the rings last done? (doubt it's that though)

Re: diagnosis anyone

Check ignition timing. Also could be the trottle position sensor, or MAP sensor.

Re: diagnosis anyone

have you checked spark leads, plugs, dizzy cap and rotor buton?

I'd start there.

Do I really have to write something funny in here?

Also low tension wires and whatever timing advance mechanism it uses.
