Vz v6 missing under acceleration

[JimbosVZcrewman]

Why is this 3.6 missing badly under hard acceleration, specially on LPG Injection, now on unleaded also??

More info required - how any kms - when plugs and coils last changed etc. Make a video on drop on here or U tube

Could be a faulty TPS. If not one of the things mentioned above. Try testing the TPS. There are several things it could be.

Plugs and coils would be my first guess is money was no obstacle.

Given it started on LPG sounds like it is an issue with spark.

Changed plugs, now 100%!! So you were right on the money there!
Thx mate for your correspondence..
Just $60 cost for set of platinum NGK's, and I spent an hour or so of time together to change them all. I also cleaned the coil's conductor underneath, where it touches plug, so to eliminate poor contact on new set. It surely fixed the problems I was having completely!
Thx again...

Thank greenacc not me mate. He was the first to mention spark. But glad you sorted it. And thanks for telling us the outcome.
