2005 Chevrolet Monte Carlo Questions & Answers
My 2005 Chevy Monte Carlo kind of spits and sputters while driving. What could be the problem?
There are several potential issues that could be causing your 2005 Chevy Monte Carlo to spit and sputter while driving. Here are a few possibilities:
- Fuel delivery issues: If your engine is not receiving the correct amount of fuel or air, it can cause hesitation or rough idling. This could be due to a clogged fuel filter, a malfunctioning fuel pump, or a problem with the air intake system.
- Ignition system issues: A faulty spark plug, ignition coil, or other component of the ignition system can cause misfires, which can make the engine hesitate or sputter.
- Emissions system issues: Your vehicle's emissions system is designed to reduce harmful pollutants in the exhaust. A malfunctioning component of this system, such as the oxygen sensor, can cause the engine to run poorly.
- Electrical issues: A damaged or worn electrical component, such as a sensor or relay, can cause the engine to run rough or stall.
- Transmission issues: If your vehicle is experiencing transmission problems, such as slipping or shifting issues, it can cause the engine to hesitate or sputter.
To determine the exact cause of the problem, it's best to have your vehicle diagnosed by a certified mechanic. They can perform a diagnostic scan to check for any error codes or issues with the engine, transmission, or emissions system.
Dash lights and radio lights dim at night
Strange behavior. I don't see a relay, but the components have logic circuitry. Not sure why--bad design. What I would do is test the dimmer. Unplug the connector and put an ohmmeter across the yellow and gray wires (terminals S and J). Ohms should go from infinity to zero as you rotate the dimmer knob.

A vacuum leak somewhere, or a tranny modulator, or both. Mechanic can do a vacuum test, or you can buy the vacuum meter and do it yourself. transmissin modulator (if your car uses one, that is) is located on the outside of the tranny and looks like a frisbee-shaped disk about the size of the base of a water glass, made of aluminum, and has a vacuum hose attached. buy at a parts store. (I'm betting on a vacuum leak, though)
Checked batt and starter have no dash lights only check engine starter will not even click
If your check engine light is on you should have it checked for DTC'S - diagnostic trouble codes ! An there is no SECURITY light lit on the instrument cluster ? In the underhood fuse / relay box is the CRANK RLY , this relay energizes the starter ! If you pull the relay out of it's socket you'll see four terminals or pin's what ever you like . You'll also see four numbers 85-86, 30-87 . 30 an 87 are the starter side circuit . 30 should have battery voltage if tested with voltmeter or a test light , 87 goes to the S terminal at the starter solenoid . 85 an 86 are the control side circuit , one should have battery voltage an the other is control from the PCM/ECM .If you can use a volt ohm meter you can see what is missing to further you diagnosis , voltage , control ! You mite want to do a voltage drop test of the starter circuit - battery cables ! Check fuse PCM/ABS 10amp left I/P fuse box an PCM (crank) fuse 10amp left I/P fuse box .If you haven't done this type of thing before you may want to take to a ASE certified repair shop ! Here I will post a video on relays !
