M30B35 w Motronic 1.3 - mild backfire on deceleration

[Rjsnyc]

On my M30B35 w Motronic 1.3 I'm having a mild backfire on deceleration. Any help on where to start?


Thx in advance

Exhaust leaks are the first things I look for.

And after that- check your TPS
Is it the correct one?
Wired backwards?

If it’s wired backwards and you get a mild backfire, would that be a - TPS report?

Only if the wiring was left in the harness to the diagnostic connector
