#30 of 50 wont start or idle/run unless you have foot on gas pedel by tjco

Nov 26, 2008 (11:51 pm)

i have 2001 malibu LS with the infamous 3.1 V6. i bought it with 55,000 mi. and now has 135,000 mi., i dealt with the passlock ignition problem long ago, $500 and a new ignition and all is well. Was having lack of power problems, took to chevy stealership and paid $350 for "pressurized fuel system/fuel injector cleaning" which helped for about 2-3 weeks then performance got worse. i had the catalytic converter repalced and immidiately the car had more power and response than it did when i bought it and kept getting better. then other problems arised, including the "wont idle down", car dies while driving, ran out of gas with little more than 1/4 tank of gas, and most repeated is randomly have to start car with foot on gas pedel, especially at higher altitudes, recently the car will NOT start unless given gas, also will not idle on it own, she runs fine and drives fine until you take your foot off the gas then it will either struggle to to stay running and die or dies instantly.
     did fuel pressure test with adequate results, repalced EGR valve, no effect. replaced MAF sensor which just recently caused check engine light, (check engine light never comes on), no effect. did cause check engine light again after resetting ECM. i did have bad alternator, repalcement of it, no effect. i did get it to stay running for about 5 mins on its own, after starting kept at 2000 rpm for 5-7 mins but ended with same results,
   Now i do have the famous manifold gasket leak. just cant afford $700-$1000 repair right now. also have done recent tune-up, new spark plugs/wires, repalced TPS sensor and IAC valve within last 12-15 months ago. im out of money and paitence, any help will be appreciated

remove The IAC valve, clean carbon crap off it (carefully), put it back in. if that doesnt work try replacing it they are only like $20 or so. That single handedly fixed my problem.

It would help a lot if you would say Classic or Z body and model engine, 3.5 V6 2.4 .

#38 of 50 fuel guage acting wierd by nemesis2401

Sep 29, 2009 (12:03 am)

I have a 1999 malibu..and having a problem with the fuel guage. its seems to never go below 1/2 tank. when i fill up, it reads full. when it reaches 1/2 it starts to go back up to full [indicating empty (I found that out the hard way)]. anybody have any ideas or know what I'm talking about? If i don't seem to be clear enough, let me know..overall it read fine(figurativly speaking). i.e: when half empty it reads 1/2..ok..when tank is at 1/4, guage reads 3/4..following me?..then when tank is near empty, guage reads "F" (full)..anyone else have this problem?

I have a 05 Malibu LS 3.5L V6. I have been having a issue with my fuel guage. If i fill up my car the gauge will drop to empty. Once i drive and burn some of the gas out it will read full until i get below half a tank. If i sit idle more than a few seconds it will drop to empty. i have only noticed it sputtering one time while idle. any suggestions other than a new fuel pump?
