Do you have OBD 2 emission system? Have you taped lightly on the MAF Sensor to see if engine sound changes? If the system is OBD 2 you can disconnect the MAF and the PCM computer will subsitute a signal for the MAF sensor and the engine will run fine, try that and get back to me.

Mercedes clk 200 petrol 1999.guys I really need help quickly please. Only brought the car yesterday and already it's a goner. Driving home it was very sluggish. this morning again sluggish....


If it runs good in park or at idle but is slugish when you try to accelerate it is likely a fuel issue. I would start with a new fuel filter. When you press on the gas you need more fuel pressure and if the pump cant get more through the clogged filter you will get that. If it runs bad even at idle it is likely a spark issue and needs new plugs and wires. I would give it a good tune up - oil change, spark plugs (platinum or iridium), plug wires, air filter, fuel filter, PCV Valve and see how she runs after that.

Car starts running rough at idle, eventually quits running. Has new plugs, wires, cap, fuel pump, fuel filter, air filter, IAC Valve, and gas cap.


Back then, Honda suggested timing belt replacement every 60,000 miles. If your Honda has that much mileage or more and has never had the belt replaced, now may be the time.

Step on gas and coughs and sputters, idles fine, changed fuel filter but check engine light still on..what else could it be?


Go to a Autozone, Advance, or Oreilys and have them scan your vehicle for free. Try to get the Code number if you want further assistance here or do the repairs that the scanner indicates. The autoparts place will describe what you need.

Car barely holds an idle and sometimes stalls when coming to a stop


There could be several causes for your stalling problem.
  • Bad plugs
  • Bad wires
  • Clogged fuel injectors
  • Bad MAF (Mass Air Flow) sensor
  • Bad TPS (Throttle Position Sensor)
A basic tuneup would rule out the plugs and wires. Fuel injector cleaner will clear most clogged injectors. Once ruled out (or if the car is running smooth apart from stalling at a stop) the most common problems are MAF and TPS.
The TPS in particular regulates idling speed under all conditions. Included in this would be while the engine is warm. If your car wants to stall unless your foot is on the gas, I'd lean toward the TPS.

1997 ford expedition will start but wont stay running unless you hold your foot on the gas pedal. Replaced mass airflow sensor because that's the code that came up. Doesn't do it all the time.


if code keeps coming up re check sensor and connections and if not done replace air filter ----if good than check fuel prssure sometimes clodding fuel filter can cause same problem and set off sensor

1991 Ford Mustang 5.0 L HO, had been setting up for 10 yrs. cranked & ran good a few trips around the block, and then stopped idleing or running smooth under 2,000 RPM. Could it be the Mass Air censor?


Mass air flow would probably shut you down. You could clean Mass Air Flow Sensor and see what happens.Try scanning for codes then looking for vacuum leaks. Use a propane tank with a gauged nozzle to help look for vacuum leaks.

Runs erratically


The idle air valve (located below the throttle body) provides the control for constant idle speed. In order to set the correct air valve opening to achieve constant idle speed, the fuel injection control unit uses information from the air mass meter, throttle valve switch and the ignition control unit (RPM signal) to regulate the output current to the idle air valve. This means that the idle valve is not affected by air leaks or a jammed throttle valve.
