Okay - hey guys - this is for my girlfriends truck.

I have done:
-plugs
-wires
-rotor
-cap
-coil

Fuel pump works - all vacuum lines work.
Replaced catalytic convertor from a 2000 tacoma last night.
Truck runs well, but ***** gas mileage. Also, it does cold start now, but requires alot of patience.

The truck does have an emissions computer - but nowhere in the haynes manual can I find the diagram or any indication that it has an o2 sensor - only for EFI and up.

Also - the truck is getting 250 km's to 40 litres of gas, that is 14mpg. I bought my girlfriend this truck for GOOD gas mileage - shouldnt it get at least over 20mpg?! What gives?

Thank you for your help.

Dave
