This is my first autumn with the Jimny and mornings are chilly here in Vermont, USA. I always warm up a few minutes, but I noticed now that it’s cooler (50-60 degrees) I have practically no power from the engine unless I warm up a full 10+ minutes.
Pushing the acceleration in either drive or reverse just gives me nothing. Super low RPMs and the truck barely moves. After fully warmed up, it seems fine and the engine responds normally.
This only seems to be an issue if the truck is parked for a few hours or more. If I park somewhere for ~1hr or so, it responds normally, though I suspect that might change as the weather continues to get cooler.
Just curious from more experienced owners… is this normal or indication of something wrong? Once it’s warmed up and running I get lots of air out of the exhaust, so I don’t think the exhaust or catalytic converter is physically blocked which I read may be an issue.
Additional context:
Service under previous ownership in Japan is noted to have involved replacing the turbocharger, alternator, battery, air filter, oxygen sensor, crankcase release valve, distributor cap, valve cover gasket, spark plugs, ring gaskets, and fuel pump and filter.
An HKS cat-back exhaust system has been installed, and the Japanese owner tells us that the fluids have been changed and that the transmission pan gasket has been replaced.
It has approximately 72k miles on it.
