hey,
have not used the gas system in about 6 months, it played up and no time.

now, just tuned gas system to run when in neutral or park at about 1000rpm.

it has never been able to idle, so i had always switched on the go.

now when i switch it over the tranny kicks down to 1st or 2nd no matter what speed i'm doing.

i.e. going constant 80km/h on petrol 1300ish rpm switch it over and tranny kicks down and revs go to 3000+rpm, and it will not shift up even if i manually put it into 3rd etc.

converter BRC at90e, boemo system

any help
