poor midrange performance?
'94 NAS D-90
Went offroading and probably broke something... before was running really well, no vibrations, - perfect. Afterwards, it has got no pull after about 2000 rpm... feels like it's got about 90 HP, instead of 180.
Mechanically, I checked the undercarriage and nothing is stuck in the drivetrain / shafts / etc
I changed the oil (we were in somewhat deep water), spark plugs, ignition wires, air filter... still no go.
So that's pretty much all the basic stuff I've tried - next I'm going to pull the distributor off and check the points, then check the vacuum hoses everywhere - but after that I'm at a loss...
