ArmyofOne Posted November 5, 2004 Share Posted November 5, 2004 thats what was in my airbox, no wonder the car was running like crap! next week is plugs and wires, fuel filter etc. i change dthe Filter when there were 140,777 on the Main odo, and 777 on the trip odo, thought that was funny. i changed the filter, but the car wouldnt stay running with the new filter. anyway, i pulled the airbox top off after unplugging the MAF, and i looked at the TB. the plate looked ok from the outside when it was closed...WRONG! i pulled the accelerator cable back and the plate stuck unless i gave it a tug, then it came open and i coudl see the nastyness that was my intake. i put some TB/Intake cleaner in the intake while holding open the plate, then i sprayed some on the plate, and wiped the plate off, it may be a half assed job, but it makes a world of difference. i put it all back togehter and started the car...ran like a champ!.

Besides, that's all the dealer does ← use STP Throttle Body/Intake Manifold Cleaner, it seems to be the most powerful, and burn the easiest. this cars intake seems to be tepermental. ayway, to cure the problem which recured today, i just wiggled the airbox. doesnt much matter since the Inner CV joints just blew.

bartkat Posted November 6, 2004 Share Posted November 6, 2004 Not sure which car had the dirty air filter, but resetting the ECU after changing the fiter and cleaning the TB might also help performance. Quote Link to comment Share on other sites More sharing options...

ArmyofOne Posted November 12, 2004 Author Share Posted November 12, 2004 Cool. The poor engine was being suffocated. ← not exactly, the poor engine was sucking in unfiltered air, notice how there is no gasket aroun the filter in the pic? thats because the gasket that was on it turned to dust when i touched it. i literally had to vaccuum it out of the bottom of the airbox. so it was sucking in dirty air for mrobably the last 100,000 miles, im amazed it still runs as good as it does. the motor/trans has NEVER told me no when i tell it to do something. and thats the way i like it. :D 99lsguy, im not sure how it is on an LS but on an es, you dont have to remove any vaccuum hoses to get to the intake, only the big rubber intake hose.

silvermate Posted December 21, 2004 Share Posted December 21, 2004 its on the drivers side fuel rail, but............... i very seriously doubt your fuel filter is clogged, that is a very uncommon problem with the Lexus V8 its more than likely something faulty in the ignition, or a broken vaccum line or a dirty throttle body, or bad Maf, but in all honesty i doubt its the fuel filter Quote Link to comment Share on other sites More sharing options...

eskaeone Posted August 21, 2006 Share Posted August 21, 2006 first thing DO NOT spray anything into your MAF (mass air flow sensor) you WILL destroy it and unless your lucky and have a good junk yard around the way you will be shelling out quite a bit of cash for this part if you were to buy it brand new.. secondly becarful when cleaning the intave valve as it might have a special coating on the valve itself and can be bad if you rub it off, third if you dont like to replace your air filter get a K&N air filter for your model, they last 50,000 miles be fore you have to clean them ,never need replacing, and add about 4+ horse power..
