Hey gang i have been tinkering with my 89mod T3's throttle body, particular throttle valve switch.

Wondering what is the general consensus of position of the adjustment hex bolt?

At present it is almost all the way over toward the air box.
My non running syncro's switch is almost in the same position.

Problem is chugging at low speed 4th gear 60K's on flat ground.
Idle is average with only a slight jitter in the bay on mounts.(AGE)
Acceleration is normal.
Decel is normal.
Plugs are good.
Spark lines are good.
Dizzy is good.
Air filter is average but cant see this hurting.
Fuel filter done 6 months ago.
running ethanol Egen95 and or 97 Bp fuels.
At startup she idles up and then comes back down to normal.

have you checked your airfilter i swaped mine for a pod type made great bloody improvement
and i turned my screw allthe way to the drivers side than 1 complete turn the other way made a lot of differance and the fuel exhaust reader said 14 at 3500 rpm so i'm happy

so u be sitting about midway of enrichment?

yep about half it's going well now i have found that they seem to be set on the lean side normally murray's is mine was i don't know if it's a europan thing good luck

Cheers will detail results.
Have u had anything like i described(chugging)?

no chugging murray had somerthing like that turned out to be his computer main board had a crack that changed by what the weather was took him a year to find it

Yeh nah it aint that bad just 4th gear doing 60k's or less. Once the revs are up or knock her down to 3rd it's all good.
I dont need to think about doing the computer board/motherboard. Surely there would have been other indications of computer failure?
