    Usually those symptoms points towards the IAC (Idle Air Control) Throttle Body Sensor not performing as it should. Take the Throttle body off & give it a good clean & renew the IAC & TPS whilst your at it, as the TPS (Throttle Position Sensor) has a large influence on general auto shifting.

    Update!

    I sold the 3.45 LSD rear hub to hub & have a total rear hub to hub rebuild completed 2 weeks ago inclusive of 28 spline hardened axles, new rear wheel bearings & seals all round, plus lapped to perfection. I decided on New Dana Spicer 3.9 Ratio Crown & Pinion Gear Set over the 3.73’s I was initially going to get, plus of course the New KAAZ-LSD-DAG3820 2-Way. Bedded in the Diff with a few light figure 8’s for half an hour in big empty car parks over 4 nights (yes, you do get dizzy lol) , no hard acceleration either – this is to prevent glazing of the KAAZ clutch plates. Drained the LSD Oil initially used in the rebuild last Sunday & used “Penrite LSD Mineral Gear Oil 85W-140” (instead of the official KAAZ Oil) also added 150ml of “Penrite Limslip” Additive. Mid range pickup is very torquey indeed, this would also be attributed also to all the other work I’ve done, but for proper get up & go then 3.9’s are the best ratio IMO. Goes Great & I can’t wait to install the new engine I’ve built on my break :XD:

    For increased compression on your S1 3800 (without having to change the pistons), you could have the heads shaved 25 thou & whilst doing so have them bowl ported & replace the valves, springs & retainers. New lifters plus higher ratio roller rockers at only 1.7:1, plus correct length push rods to suit will be a good start without compromising clearance.

    Thanks Mate,

    I really appreciate your feedback, will have a look through my notes from the 3800 build when I can, to give you an idea – are you keeping the motor N/A or applying F.I. on top & if so, what type – Turbo or Centrifugal? Plus it’s a holistic application with the driveline, intake & exhaust to gain maximum performance as you know.

     

    Cheers!

    Cool, I do have a photobucket account but as I’m at work right now I can’t be uploading photos etc here :) Irony is I’m a Graphic Designer.
