Hi all.
Not sure if anyone can shed some light on this one as it has me stumped.
Just over a year a go I built a new 4.0 V8 to go in my Peggy. Think there is still a posting on her regarding all the fun i had, But it recently started to get a taping noise on startup but this did clear after a few secs. I decided to open her up again and find the fault. turned out to be nothing more than wear in the rocker shaft assemblies. any hows more new parts fitted and what a difference. it is silent and seams to drive better. or so i thought.
I took her for a run on sat and when i floored the pedal to over take some traffic. the box kicked down as normal but when the revs get to 3000. the engine holds back. its like the engine has hit the rev limiter and starts to bounce. if that makes any sense. I thought the rev limited was set at 5500 rpm on the 4.0 litres....
My thought was. the battery has been off for a few days. and wondered if the auto box and engine manegment have some how defaulted to some factory setting? Is it a mater of reseting all the adaptive values. i was going to give it a go over the weekend. but if anyone has experienced this and may be able to shed some light it would be appreciated.
Thanks
Bryan
