Replying to: unclestick (Apr 02, 2008 10:11 am) I did a search and found this:   http://cf.us.biz.yahoo.com/bw/080326/20080326005392.html?.v=1   You'll have to read the details. It only applies to certain vehicles and not all leaks.

Hi All - First time here, but I need help. I have a 2005 Malibu and I have approx 43k miles on my car. Today my baby is at Chevy getting another Fuel Pump. Yes! Another. I had one put in before the Manufacturers' warranty expired (36K ?)and now I'm told the same thing...."it was a faulty fuel pump".....What do I do? I don't know what I'm supposed to do to prevent this from happening! I use Chevron and Shell gasoline and rarely let it get below 1/4 tank. Help!!!

Replying to: unclestick (Apr 02, 2008 9:39 am) Hello, you must have a intake air leak,,,, also form my past experience DO NOT use the stock gasket,,,, are you changing gasket due to water leaking? its a problem with these engines, mine happened twice, first time ruined the engine, second time right after installing new eng, the gaskets are worthless, and chevys update to it is no better,, Fel-Pro puts out a problem solver gasket, it was on back order when I was looking for one, but I found one in Mich, a eng rebuilder had some, so far its holding,the gasket looks so much better than the orig, hope this helps,,, but you are pulling in air somewhere I think for a runaway idle......

Replying to: bestdad4us (Mar 08, 2008 9:18 am) The original intake gaskets, as well as the " updated " one from chevy is no good, I found, Fel-Pro, makes a problem solver gasket, so far its holding, as I had two original ones fail, and a ruined moter becasue of this,

Replying to: 05malibu (Apr 03, 2008 11:12 am) I would say a bad batch of fuel pumps. What reason did the dealer give for such poor service?
#20 of 44 Still having the same problem! [bestdad4us] by bestdad4us Apr 22, 2008 (7:01 am)
Replying to: bestdad4us (Mar 08, 2008 9:18 am) At the time of my last posting, we had taken the car into a garage. They said the sputtering the Malibu was doing was due to the fuel pump failing (diagnostics). They replaced that, fixed the gasket leak, replaced spark plugs, and also replaced the thermostat. Since then we've drivien it 1000 miles. The other day as I was sitting at a light, the sputtering returned! It feels like something is missing or skipping - like it wants to stall but doesn't. It'll kind of sputter or jump a few times and then run fine. Previously it would do this randomly while driving as well as while idling. Any ideas????

#22 of 44 Hesitates/loss of power while driving by camoguy1 Jun 16, 2008 (11:55 am)
I have a 99 Malibu, 2.4L with 95,000 miles on it. I recently had the fuel lines changed on it. When the car was returned I filled the tank, and almost immediately the car started experiencing some hesitation while accelerating. This occurred while the tank was right full. As the level of fuel decreases, the hesitation seems to disappear. At 1/4 full tank the car ran perfectly. Once I filled the tank, the problem came back. The mechanic inspected it, took out the fuel pump and ran a pressure test on it. He determined the fuel pump was faulty so he replaced it. Filled the tank and it seemed to work fine. I just filled up the tank today and the problem is back! New lines, new pump, and new tank. Mechanic drove the car while it was experiencing this problem, ran multiple scans on it and everything came up clean. Determined it is not the ignition control module (already changed that a year ago). Does anyone have any similar problems? Suggestions?
