the fuel economy on my '93, 4.0, manual, 210k has "tanked". i've got a check engine light. codes, (checked twice)
12- battery disco
36- air switch solenoid circuit, i cannot find any reference in haynes, fsm, 'net, 1 reference here, something regarding a second o2. my '93 has just one, if memory serves(it's raining, i'm a bit reluctant to crawl under it right now).
33-ac clutch, i've put it on a switch
35-cooling fan relay, switched as well
22-coolant sensor or circuit, i assume it is in refernce to the front sensor, which a) is run to an aftermarket gauge, no longer the computer. and b) which i believe is not involved in engine management, the rear one handles that.
any ideas?
