I'm new to the Mustang scene but not new to cars in general so please feel free to use technical jargon.
I did search but didn't find the exact answers I'm looking for so please forgive me if these have been asked a thousand times.
I just bought a 93 5.0 LX convertible with only 65K miles and have a few questions about how these cars normally behave.
The car is totally stock (as far as I can tell) except for dual 2 1/2" exhaust with turbo mufflers. The CATS have been removed.
1. I took a relatively long highway trip weekend before last. The ambient air temp in the area I traveled through was around 106 degrees. The temp gauge in the car started out reading right in the middle but once I got on the highway steadily climbed to the 3/4 mark and stayed there regardless of what I did. I ran the A/C for a while and it didn't seem to affect the operating temp of the engine. Is this normal for these cars? I thought it seemed a bit hot.
2. The speedometer/odometer seems to read around 10%-15% low. Again is this normal error for these cars or has someone replaced the rear gears with a lower ratio. Is the ring gear stamped with it's ratio or do I need to count driveshaft revs to determine the ratio. I'd rather not open the diff housing but if it's stamped I'd know exactly what the ratio is and get a chance to change the fluid.
3. I seem to be getting about 15 MPG around town, is this low? I have an AOD so I understand the MPG will be lower than a manual but it seems a bit low. I ran the KOEO and KOER tests and got all 1s and ran the cylinder test and got a 9 so all tests passed. Will the codes show a bad O2 sensor or could the sensor(s) be bad and not throw a code.
Thanks in advance for any answers advice you guys give and I have to say this is one of the better car sites I've visited. Not a lot of flaming and arguing about stupid things.
