Hey guys, sorry if this is in the wrong spot.
just seeing if anyone else has had this or knows what else it could be
so ba xr6t cold start will not rev over about 4K sounds like it’s a rev limit and also will have smoke coming out of exhaust as well as smelling a lot like it’s overfuelling, But leave it for a few mins to get up to temp and she’ll rev till its hearts content,
also every now and then after a quick stab of the throttle The revs will drop all the way down till it nearly dies.
Any info will be great cheers
