Might want to chg. the fuel filter, (if you havent already), also do a fuel pressure chk. filter could be pluged up and in turn weaken fuel pump.

I had the same problem. Turned out to be an O2 sensor.

I have a 93 mercury cougar, 3.8. When I first start it up and give it gas it'll sputter then stall and the check engine light will come on and it won't start again unless I give it gas and even after it...


It needs a gascap. You can get a free scan at Autozone, Advance, or Oreilys. A Code will be set if the cap is loose or missing.

There are other possible reasons for your drivability problems, but get the scan, put on a gascap and fix scan results.

Check the mass air flow sensor (clean both heated wires with carb cleaner and Q-tip). Remember...cleaning does not always work...sometimes they are actually bad. Also check map sensor. Check for vacuum leaks at all hoses and fittings. If engine rpm drops sufficiently, engine vacuum will drop which may have caused a/c malfunction (controls work with vacuum signal) so I wouldn't worry about that 'till the run problem is dealt with.

Eldorado stalling problems


Sounds like either a MAP sensor or TPS or both. TPS will impact the throttle control and if its stalling once its warm, this would be where I'd look. Best of luck.

My 93 Lumina did the same thing and a simple tune up solved the problem. For whatever reason, the rear middle plug wire goes bad before the others.

93 chevy lumina euro won't stay running


if you can check for spark when it wont start and fuel pressure and the service port , would be great information , otherwise pattern failure is ignition module and crank sensor (replace them as a set) , after cools off it will run again.
