Typically there is no malfunction indicator light associated with the condition. The engine control system sensors are supplied a 5 volt reference signal to ensure properly scaled readings to the engine control module (ECM). If a large current draw flows through the circuit supplying the 5 volt reference, the input signals, as read by the ECM, will be skewed low. The ECM program will store an incorrectly low throttle position sensor signal as zero. If the reference voltage returns to normal, the ECM will interpret the resultant high throttle position sensor signal as an open throttle and idle air control steps (throttle follower) will be added accordingly, causing an increase in the engine rpm at idle. The A/C pressure transducer has been found to be especially vulnerable to shorts during the engine crank process. Electrical wires in the engine harness that are unprotected and rub on structural members also will cause the problem. Inspect all wiring and sensors associated with the 5 volt reference signal for shorts and correct as necessary. If the vehicle also has a condition associated with the air conditioning system, diagnose and correct as necessary. With a Techline Diagnostic Tool, read the throttle position sensor, manifold absolute pressure sensor, and A/C pressure transducer voltage with the key on-engine off. If all three voltage readings are skewed below their normal ranges, inspect the A/C pressure transducer. If all three voltage readings are within normal ranges, disconnect the battery for one (1) minute, reconnect and start the engine. If the increase in engine rpm at idle condition is gone, inspect the A/C pressure transducer. NOTE: On the LB6 (2.8L VIN W), LHO (3.1L VIN T) or L01 (3.4L DOHC VIN X) engines, If the ECM Is without battery power for any reason, then the Idle air control valve (IACV) position information for a stable satisfactory engine Idle Is "lost" and replaced with a default value. To correct the IACV position Information, perform an Idle relearn procedure using a Techline Diagnostic Tool. You can also manually relearn the Idle by following the procedure below. 1. Remove battery power for one (1) minute. Restore battery power and place air conditioning controls (if equipped) in the "off" position. 2. Firmly apply the parking brake and block the drive wheels. Start the engine, shift the transmission to drive for automatics and neutral for manuals. 3. Allow the engine to run until the engine cooling fan has cycled once, or a maximum of 10 minutes. 4. Turn the ignition key to the "off" position for at least 5 seconds. 5. Repeat Step 2. 6. Allow the engine to run for at least five (5) minutes. The correct IACV values for proper idle control will now be stored.

    What you can also try is cleaning your IAC , there are two hex screws holding it, it's on your throttle body, make sure to disconnect your battery, use a throttle body cleaner, lint free rags, try not to turn the plunger on it when cleaning it, also clean the port where it sits you can use Q tips to wipe it out, you can also clean your EGR valve to

  • What was the reason for changing the plugs,wires,fuel filter and fuel pump ?
  • Was it running good before ?
  • Could be crossed spark plug wires, check to see if they are going to the right plugs
  • Check to see if fuel filter is on the right way
  • Check to see what your fuel pressure is and if it's within specs

Testimonial: "it was cutting out some so changed plugs and wires and that didnt help so changed fuel filter and a line broke that goes to fuel pump so put new fuel pump in"

Check your battery terminals and clean them with a wire brush if they are corroded and make sure they are tight. If this doesn't work check the following: Fuel tank empty?, spark plugs incorrectly gapped if they are new, if old- maybe replace them, possibly faulty ignition coils, then maybe the crankshaft sensor is bad or timing chain is broken. I got the latter of information from the Haynes Repair Manual. Check this stuff in order. Good luck.

SOURCE: my cavalier won't start

Okay there should be a plug on there make sure it is pluged in all the way. If you have someone to help you pull one of the spark plugs out plug it in to the wire (Do Not Hold Wire with Bear Hands) use insulated pliers.try to start car if you don't see a spark from plug then it means that the coil pack is bad. If it does spark then it is possible thet it may be a fuel problem.

Try manually locking the car (with the key), on the Driver's side. Then wait about a minute, for the security system to reset and unlock it (again Driver's side with key).

Spray aerosol carb cleaner into the throttle body while an assistant tries to start the engine. If it runs for a few seconds then quits, you are not getting fuel into the engine. Check the fuses. You might have blown the fuse for the fuel injectors (possible if you removed any of the injector harnesses) or the fuel pump relay.

What makes a 2004 cevy cavalier sputters off and on until you reach 50mph?


Scan for check engine codes, sounds like you are having a misfire problem. Common causes include clogged fuel filter, weak fuel pump, worn out spark plugs, failing sensors, weak ignition coils or spark plug wires....etc.

2002 cavalier 2.4 will not start fuel pump runs has spark


FUEL PUMP ONLY HUM'S FOR 2 SECONDS WHEN YOU TURN KEY TO ON, NOT START, POSITION. YOU CANNOT HEAR PUMP RUN WHEN CAR IS RUNNING ! THIS 2 SEC., IS THE PUMP PRIMING ITSELF TO START ENGINE. YOU MIGHT BE HEARING EITHER THE POWER STEERING OR WHATEVER, NOT THE FUEL PUMP!!!!!! GIVEN THE YEAR OF THIS CAR, YOUR FUEL PUMP COULD BE BAD, CHECK FUSES, RELAY, GROUND WIRES, TO PUMP, ALSO CHANGE YOUR FUEL FILTER !!!!! AIR FILTER ALSO !!!!!!! SPARK PLUG WIRES SHOULD ALSO BE REPLACED !!!!

I had a similar problem with an earlier model Cavalier, with the problem being much more pronounced. The fuel injector nozzles on two cylinders turned out to be the culprits. Once replaced, the car ran beautifully like it always had before.
