yes EFI has a virtual choke, no it's not physical at all.
its a fuel table.
all ECU has Fuel tables, most are 3D. (or more complex)
on a cold engine the ECU uses a cold fueling table. (but if spark is bad, the engine just floods)
Ive never seen an old sidekick that did not need at least 10 things wrong,
never fully done the 60k mile service,
spark parts and filters. and cam belt.
A full tuneup is amazing, with out good spark no otto cycle engine can burn fuel or do so completely.
the the car bogs up hills, and fuel filter is 90% packed up.
