on behalf of a friend :D ................. more gremlins in his r

i seem to have a problem running my R once it reaches its running temperature of about 80-85'c.
when i try puttin my foot down to advance from say 40mph-50mph in 4th gear the timing drops off.
when the oil cools slightly it does run better.
i've recently put the car on the datalogit program and everything else is running ok.
my timing is currently at 20deg's but any lower and the problem gets worse unless advancing the timing.
the dizzy is set right back which seems odd compared to everyone else's where there's seem to be positioned in the middle of the 2 sliders.
everyone is stumped and i need some help.

Hi,

is it a lull before/as you accelerate or the timimg actualy drops off.

If its a hesitation check the fuel pressure regulator, disconnect the vac hose, plug and test drive, if its still there then check for an air leak by pinching the blow by hose.

Check the fuel pressure and check wastegate control solenoid.

Whats the idle like when hot
Whats the idle like when cold

Regards
