Car Forum / Chevrolet / Chevrolet Malibu / November 2004cleaning the Air Intake
my 2002 malibu makes a radling engin noise when its about 2k rpm so I asked a friend and he thought it would be a dirty air intake or a leak .. so got one of those thro-body cleaner and toke the boot off an it wasnt that dirty ! just a littel yellowsh ... I cleaned it anyways.... and also changed the air filter .. the noise is still happening ! the cleaner can says to spray inside ...but Im not too sure if I should do that since a mechanic worned me not to that ! why would they put on the insruction to spray inside if it would harm the system ?! anyways ... is there anything else would cause this ?? spark plugs or fuel filter ? thanks in advance D Sounds like pinging. Try switching to 91~93 octane fuel for about 1/2 tank & see if the noise goes away. If it does, you have problems. Come back & report to us. -Mike -- A happy kid behind the wheel of a 98 Mustang GT Cold air intake FRPP 3.73 gears Steeda Tri-Ax Shifter Full Boar turbo mufflers Hi-speed fan switch 255/60R-15 rear tires Subframe connectors > my 2002 malibu makes a radling engin noise when its about 2k rpm > so I asked a friend and he thought it would be a dirty air intake or a [quoted text clipped - 18 lines] > > D I've been using the 89 octane grade for the past month ... no change ! still does the same :( > Sounds like pinging.

Switching to higher octane reduced the rattling. This makes me almost 100% sure that it's pinging. Go real easy on the throttle until this is resolved. What I would do is run a can of Seafoam cleaner through the gas tank (can be had @ $5.50/can from Carquest, O'Reilly, Autozone, etc) and run 87 octane. Pour in the Seafoam cleaner first, then fill it up with 87 octane. Drive EASILY the entire tank... don't ever go full throttle if it's causing pinging... unless you want a dead motor. See if this reduces/eliminates the noise. If it reduces it, run another can through it. If it reduced it in the first can, but didn't eliminate it during the 2nd... then come back & let me know. Also, check spark plugs... see what condition they are in. You might try running 1/3 pint of Seafoam through the PCV valve or any vacuum line that will let it go to all cylinders... if you are going to try this, do it while the car is warmed up & running.. after you poured in 1/3 of a pint (1 pint = 16 fl oz = 1 can), shut the car off for 5 minutes. Start it back up. Expect a lot of smoke ;). The smoke is fine... drive the car fairly hard until the smoke stops coming out of the exhaust. This'll clean out a lot of carbon buildup in your engine. Hope this helps. -Mike -- A happy kid behind the wheel of a 98 Mustang GT Cold air intake FRPP 3.73 gears Steeda Tri-Ax Shifter Full Boar turbo mufflers Hi-speed fan switch 255/60R-15 rear tires Subframe connectors > I used 92 for the last 2 tanks ..littel but less knocking noise. > [quoted text clipped - 56 lines] > > > > > > > > > > D Mike, thanks for all your help man .. :) the car is still under warrenty, do you think GM cover this and do the work for me under warrenty ??

You can copy specific messages that you want to save too... but if you can't retrieve old messages still, best suggestion I can think up is check the newsgroup messages via Google :(.
