19xx 850 rough running, TB or MAF?

[GDavid]

Hi all. Necro here, but I'm looking at this stuff currently:

Old 850 (Injected NA) intermittently running very roughly-

• Advised Throttle body clean- (pictures on thread pg 1 are a great help)
  
  Will try the disconnect MAF (Motor off) and check.

Disconnected MAF, ran much better then observed similar running conditions. (Don't believe it is related to duration motor has been running)

My wife seems to think it gets worse when the aircon is being run (I can't seem to prove that).

Unsure if this is correct part for my vehicle...
