1997 Mercury Grand Marquis ProblemsTransmission Failure Common Due to Front Pump Failure
Transmission problems are common in this model, often as a result of a failed front pump. The pump loses its ability to create hydraulic pressure, which an automatic transmission needs to function. A sign of front pump failure can be a whine type noise.
The throttle position sensor (TPS) may fail. Common symptoms of a defective TPS can be rough idle, hard starting, hesitation on acceleration, poor fuel economy, and stalling.
The composite (plastic) intake manifold may crack near the thermostat housing and cause a coolant leak. Ford released an updated manifold that was reinforced to prevent a recurrence. No recall was issued for this problem but Ford did extend the warranty to seven years on some models from the date of purchase.

random speeds timing!
starts up . runs smooth!
I bought a car from a dealer that had a check engine light on. He told me it was a misfier and cleared it, but now it came on and mechanics are telling me it's something else (catalytic converter). I'd like to check if he was telling me the truth.
