How's it going everyone, my name is Scott and I'm new here. I wish I had joined the Ranger- Forums due to better circumstances but I'm thinking it'll end up being a good thing all-in-all! Well, down to business.... A couple nights ago, I jumped in my 03 Ranger 3.0L-FF 2WD w/AT to hit the store. I've been running with a trouble code since I got the truck a couple years back(not sure of the #, but it has a gutted thermostat from P.O. and when it's cool out it doesn't reach hot enough temp for the ECM to run in an 'open loop') without incident. I started her up and dropped it in Drive and it felt like it 'popped'(like when a standard pops out of gear kinda). Truck proceeded to 'protect' mode(rev-limiting)... or so I thought. Not the case- whatever happened caused the O2 sensor preheat circuit to blow the fuse(power dist. box , slot#41) and now it pops a new one instantly or as soon as you put juice to that circuit(turn key to 'run' pos.). ECM is dropping 11 codes now, 10 are 'new'. 5 codes are trans related- P1747, a TCC code, and 3 solenoid codes I believe. The other 5 are engine related to the other, simultaneously occurring 'new' problem, which involves the O2 sensor preheat fuse blowing. This is causing the truck to run RICH to the point of stumbling/very rough idle and the exhaust smoking(unburned fuel). I let the truck 'warm up' for about 5 mins and it seems to run better after the sensors are heated(that's my guess anyways LOL). When I get home later today, I'll check out the VSS, list the EXACT TC's and check that ABS light is lit + more tranny 'symptoms'/description of current operation. Thanks for reading my post!
