2004 Malibu Classic lost power going up a hill. Did not quit, but lost power on accleration. After regaining power hesistated again after acceleration

Search for the engine model ECOTec 2.2 rather then Malibu. It is very easy to replace the plugs, they are DEEP inside the engine so you will need a 6" socket extension for the spark plug socket. Needle nose pliers were required to retrieve the socket on the first plug. Don't push down hard on the plug, just enough to engage the nut. Full screen photo sequence is available at:

SOURCE: 2004 Chevy Malibu Classic and problem is turn signal goes out

the hazzard switch is together with the turn signals, so if they are not working properly, check hazzard switch. the switch has a built in timer for hazzards and turn signals.

Standing at the front of the car looking at the intake manifold, its on the right hand side of the manifold about 6 inches down from the valve cover under a black cap with a 32mm top on it.

There can be a misfire too from the cylinders.

An engine that hesitates, stumbles or misfires when accelerating or when it is under load is an engine that is either sucking too much air, not getting enough fuel or misfiring. If the Check Engine Light comes on, you may find any of the following codes:

• P0171, P0174 Lean fuel condition codes
• P0120 to P0124 Throttle position sensor codes
• P0222 to P0229 Throttle position sensor codes
• P0400 to P0409 EGR related codes

If there are no misfire codes, a common cause of acceleration stumble is a bad throttle position sensor (TPS). The TPS tells the computer how far the throttle is open. The computer uses this information to determine how much fuel is needed to maintain the correct air/fuel mixture and when extra fuel is needed if the throttle suddenly opens wide.

Another common cause is dirty fuel injectors. If varnish deposits have built up in the tips of the injectors, they won’t spray as much fuel as they normally do, or will “dribble” fuel instead of spraying a fine mist. This creates a lean fuel mixture and conditions that are ripe for stumble and hesitation (also misfire). Look at short term fuel trim (STFT) and long term fuel trim (LTFT) with your scantool. If the numbers are high, it tells you the engine is running lean and the injectors need cleaning. Treat mild cases with a high quality fuel-injector cleaner additive. Severe cases require professional cleaning equipment.

Also if this sensors apply to your vehicle, camshaft sensor or crankshaft sensor if sensors bad you don't get any spark. Also run a scan on the car.

Good luck and rate this solution, please.

sounds like a clogged fuel filter. you need to have the engine pressure checked for leaks, you can rent the pressure checker at autozone, it connects to ur radiator and u pump pressure into the cooling system if u find water leaking around the head u know u have a blown head gasket. if ok then check the cylinder compression should beable to rent this also. it screws into the spark plug holes has a gauge on it. alternator problem w/ the light is probaly you need to tighten the belt.hope this helps!!!
