    Regal GS. fianally got an error code. Missing /running rough very inconsistant. code was "mass air frequence low"
    The problem seems to surface when engine is warm or under load. A real tough one to solve ! Mass air moldule tested OK. Plugs and wires changed. Ignition module checked.

      I believe you got the P0102 DTC, in this case, your MAF can be disconnected, dirty, faulty. What you dont want to happen is your ECU is busted, but dont worry, its a very rare case

      Replace the MAF sensor after trying to clean it. The cleaning may not help. Probability is greater than 90% if the code is a P0102.

      Replaced MAF as you suggested and running good so far. It was replaced once before but box appeared open and I believe the part was returned bad. Thanks

      Apparently nobody is taking you seriously because if one of my customers gave me their 97 Park Ave and said fix my light it would be fixed and billed. Maybe they don't know what to do. Try a different shop? Or try it yourself. Buy a $50 code reader, attach it to the diagnostic connector under the driver side dash and read the fault codes and then repost with those codes and we can help.

      The fuse or the dash voltage regulator or the gauge is defective. Most likely replacement is the best way to resolve this.

      Under the car along the LH frame rail. Great idea to replace it if it has been in there for more than 30K. It will not likely solve your stall unless the filter is totally clogged where you cannot blow your breath through it after you remove it.

      Did you check the condition of your engine oil if low of contaminated? Add oil or change the oil with filter if necessary. Check also if air filter is blocked. When the last time you replace the fuel filter, maybe it needs to be changed. Inspect all above recommendation and correct it. If problem persists just post another question with its details.

      First check the fuel pump relay, here it is;

      Faulty Fuel Pump Relay Symptoms

      To identify the malfunctioning symptoms of any car part, you must observe its effect on working of connected parts. Every part of the engine assembly is linked to the working of other parts. So bad fuel pump symptoms can be identified by the effect of the relay malfunctioning on connected parts like the fuel pump and the car engine. Here are the prime bad fuel pump relay symptoms:

      Engine Goes On a Strike
      One of the symptoms of a faulty bad fuel pump relay is the engine cranking up but not starting. This point towards a problem with the fuel delivery system and it may be that the fuel pump relay, which is the culprit.

      Erratic Engine Function and Delayed Start
      Erratic functioning of the engine at the start and delay in starting up can be an indication of a faulty fuel pump relay. That is why; if you consistently notice a delay in engine starting, check the fuel pump relay.

      Absence of Fuel Pump Working Sound
      Once the relay stops functioning, the fuel pump will not switch on and the familiar sound of fuel pump working will not be heard. Ears trained to hear the normal sounds made by the car at start will notice the difference.

      And;

      Symptoms of a Bad Fuel Pump

      Fuel pumps stop working due to a variety of reasons. Once this happens, the supply to the injectors is automatically stalled and the vehicle stalls as well. The effect is similar to the problem of running out of gas. Another problem associated with the pump is proper functioning of the electrical mechanism of the pumping system. The electrical supply consists of devices like the relay and the fuse. If the fuse or the relay develops problems or blows off, it will again result in breakdown, as the driving mechanism for fuel supply is cut off.

      Another reason of a bad fuel pump is overheating. If the fuel pump gets heated frequently and within few minutes of turning on the vehicle power, it is a sign that the pump needs replacement. A bad fuel pump will also show signs of frequent stopping or intermittent breakdown. It will work for around 15-20 minutes and stop working. Once, the vehicle is allowed to remain idle for around 30 minutes, the engine gets cooled off and the pump functions normally. Such a problem is an indicative sign of a bad fuel pump.

      If the flow to the fuel injection system is not constant, the engine may develop problems. Signs include a hesitant start or a stumbling problem on ignition. If small, unwanted debris or grainy particles enter the pumping system it can cause vehicle breakdown, thus, abrupt stopping of a vehicle can also be considered a symptom of a bad fuel pump. If the filtering mechanism develops a problem or gets struck up with impurities, the engine will show symptoms like rough firing and fickle working. A reduction or drop in fuel supply to the engine causes symptoms of a low power engine and working problems if the problem persists for a long time.

      Perhaps the engine is overheating, that's why your engine stalls. Check the coolant level if correct adds if necessary. Conduct radiator pressure test to determine if there's a leak in the system; also a compression test for the combustion chamber. Check also the condition of your spark plugs may be they are worn to excess.

    I hear a squeal in the engine compartment just after starting the vehicle. could this be the A/C clutch?
    the noise stops within two seconds after starting. the diagnostic center indicates low refrigerant and disengages the A/C.

      Its probably just a loose belt, i dont find any reason why your compressor will give a squealing sound because of low refrigerant.

      Did you check the condition of your battery if it has a charge? Also its cables if properly fix and free from corrosions? Check the wiring from battery to starting motor as well as to the coils if worn or attachments is loose. If the coils are failing, replacement is necessary.
