Hi all,

I have searched high and low for an answer to this issue but can't find it.

I have an automatic 17 plate L200 barbarian, when idling (I.e at traffic lights) in drive the engine rpm usually sits around 1000rpm but continuously dips to like 600rpm for a few seconds then come back up. This is a continuous problem and repeats every 3-10 seconds.

In neutral or park this issue does not exist.

Do these symptoms align with a suction pump control valve issue or do you think it would be something else?
