  1. How to get to ECT sender?

    Just took a 15-mile test drive with Forscan hooked up. The code P0125 came up after about 10 miles. On the streaming diagnostics. the ECT temp started at 23C (much higher than ambient of 5C) and never got above 38C. The temp gauge never moved. The heater, even at full hot, gave hardly any...
  2. How to get to ECT sender?

    Thanks. The thermostat and water pump are both less than a year old. Engine is warming up just fine as far as I can tell by the feel of the rad hoses and the increased volume in the coolant expansion tank. There is a slight amount of heat when I crank up the heater, but very little and much less...
  3. How to get to ECT sender?

    Recently, the temp gauge on my 2001 2.3 Duratec failed. It stays at cold and never moves even after engine is up to normal temp. I understand that I need to test the gauge and wire, and then the sender, in that order. I have found the sender on the coolant pipe behind the head. Above it is a...
  4. 2.3L ('83-'97) Potential.

    Ouch. I didn't know the gears were the weak point. I'd hate to sell this great truck.
  5. 2.3L ('83-'97) Potential.

    Thanks. I'd be happy to add a turbo to get what I need. We have had turbocharged Saabs for ten years now and I really like the fuel economy when you keep a light touch on the throttle. My need for more power is more related to carrying loads and towing than for speed. I use the truck around the...
  6. 2.3L ('83-'97) Potential.

    Wow! Not for me. When I do the eventual rebuild on my Duratec I'd like to get it up to around 200-225 hp, possibly even without turbo, while maintaining good driveability.
  7. 2.3L ('02-'11) Sudden Misfire

    Thanks, pj. Oil use is <1 quart per thousand miles. I haven't smelled any oil in the exhaust. I ran a compression test Wednesday. Results were: 1 168 2 170 3 160 4 164 I'm stumped.
  8. 2.3L ('02-'11) Sudden Misfire

    Installed new coil pack. No change. Still misfires under load from 1800-2500 rpm. But while Forscan and I can both see and feel the misfire, it doesn't throw a code. Smooths out when I get the revs up. Still running rich. Now the mystery begins. Unless someone here knows what I should look for...
  9. 2.3L ('83-'97) Potential.

    So how built is that engine? How many HP? How much boost?
  10. 2.3L ('02-'11) Sudden Misfire

    I guess it's a boring question. Today I pulled the plug from cylinder 4 (which was the one noted in the DTC). It looked perfect. I am pretty sure the coil is the problem and plan to get a new one tomorrow. Attached is a screen cap of the Forscan log I did this morning with the truck at rest in...
  11. 2.3L ('02-'11) Sudden Misfire

    My '01 2.3 Duratec with 295K miles suddenly started misifiring last night and threw a code for cylinder 4 misfire. Today I took it on a 10-mile test drive with Forscan running. It misfired quite badly although the CEL did not flash. I tried to attach the Forscan log to this post but apparently...
  12. Fuel gauge gone crazy

    Thanks. The gauge ran fine for about a year after I installed the new fuel pump.
  13. Fuel gauge gone crazy

    My 2001 Ranger, 2.3L Duratec/manual crossed 295K miles a month ago. But starting last summer the fuel gauge started reading very high, even pinning at the top of the scale, way above full, after a fillup. It gives inconsistent readings - sometimes nearly accurate, sometimes high. I put in a new...
