My 2003 Chevy Malibu 6 cylinder seems to be losing power from time to time. I've noticed it uses a LOT more gas than it use to even on very short trips. When driving even on a flat road it seems t

Replace the struts on the trunk lid. There are two of them. Over time they lose the gas charge and cant bear the weight of the trunk lid.

Sounds like a throttle position sensor. It is a variable resistor that moves with the, "gas" pedal. What happens is it wears out in the position it spends the most time, say 40 mph. Then it can't properly report the position of the pedal to the car's computer, it looses connection, and the computer thinks you just let off the pedal completely, and the engine goes to idle. A slight movement of the pedal goes to a less worn spot, and the fuel flow comes back to the engine.

Inspect the old ignition cycle which is out.Is there any problem noticed of Ignition cylinder getting worn out.
Because when issue of ignition not turning off,its faulty ignition lock cylinder or faulty ignition switch.I suggest re-inspect the new ignition cylinder.

Thanks.

there is a lot of problems with the eco motor and thier ignition control module. get a use one to try it out

you can call Auto Zone or go to their web site and get the right specs,I've always use their web site www.Autozone.com.

check your timing, fuel filters, check your points, or spark plugs is your rotor cap where it's suppose to be and is it good? i've always disconnected the battery and it seems to reprogram it's self. see if that works

Hi Jacki, If you are losing brake fluid it must be leaking from somewhere and the places are limited. Fluid can leak from any one of the four wheel brake cylinders, the master cylinder, the ABS pump and valve unit, the master cylinder or cracked or broken metal or flexible brake pipes. Wherever the leakage is, it must be visible and detectable, as the fluid will make the area wet, If you look at each one of the four wheels, I'm sure one will have been marked by the leakage. The ABS / Traction control are separate from the Emergency brake warning light. The latter (E Brake) warns of loss of brake fluid. Whenever you top up it will extinguish, but illuminating again when the fluid has leaked out! The ABS and Traction control warnings will come on when an electronic signal fail to be transmitted and thereby triggering a fault code. These codes will be extinguished when the vehicle is connected to a scanner and the faults are deleted from the vehicle computers memory. You will most likely find that the wheel cylinder which is leaking has contaminated the pick up sensor which sends the signal to the ABS / Traction system. It will likely need removing, cleaning and then refitting. I am very sure that if you take a flashlight and lay down, even without crawling under the vehicle, you can identify where the leakage is, and point it out to those experts who it would seem have been misleading you. I doubt the leakage will be on the master cylinder, as having two unrelated faults would seem to be stretching coincidence a little far. (But I may be wrong and two problems may have come separately together! I believe the two are related to one wheel cylinder which has contaminated a sensors, The leakage is the most serious problem, as it can leave you without brakes! have that seen to very urgently! In fact NOW!!!! Regards John

Sounds like you need to disconnect the Radiators' electric fans and have them tested. You absolutely must have them working, or your car will overheat. Check to see if the Temperature guage is working.

You need to go to a good autoparts store and have them test the fans and charge and test your battery. You may need some sensors to activate the Radiator fans, but you could be running the battery down with shorted cooling fans.

There are also Relays which work with the Radiator fans. The overflow will stabilize once the water gets into where it belongs. Make sure your Thermostat is not clogged with the sealer.

The ignition lock cylinder is damaged. I've replaced so many of these, and if I recall correctly (I don't pay much attention to parts invoices...) the part is about $90 and its .6 hours to replace. Unfortunately this is a DEALER ONLY repair.

get a 6 cylinder motor drop in this is best gas saver for most vehicles 4 cylinders dont have the ability to push all the weight of a vehicle but runs smoothly
6 cylinders are as i put in words are evenly balanced for everyday use and not gas guzzler either
