the throttle is EXTREMELY sluggish and laggy..the car also like shakes weird?

ive got a 2010 ISF 74,5xx miles..

Seen several people on here say their car was filled with 5 quarts like a normal IS needs instead of the 10 quarts the ISF needs, I assume this would throw some sort of warning code but I would check that first.

also check to confirm that your airbox is fully sealed. More specifically - make sure it is sealed all the way around. Mine was unhinged underneath - car felt super slow and the intake sounded weird.

not the oil...just checked...

What Vervish said above check the air box because they might have not snapped all the retaining clips back together if they checked the condition of your air filter and the MAF is so sensitive that it might cause issues??

Would a loose air box cause the shaking he's reporting?

Mine didn't shake - it just felt slow at high RPM - almost like the car was choking.

Was the battery disconnected? does this always happen?

If the oil level and air filter are ok then maybe the battery was disconnected and the ECU needs to re-learn your driving habits, but it shouldn't be so bad that it's shaking.

Try hammering the car a few times and see if that solves the problem, if it shakes again in anyway then I'd say get it checked out, shouldn't be shaking violently.

Check for loose connection near the MAF , Once mine was over tightened and pinched the plastic at the MAF housing letting unmetered air in and it was shaking / almost stalling at an idle, spitting / sputtering while driving on HWY , finally got a CEL and got home to find that it was only this minor air leak causing all this / after I fixed it, ran like it should

^ ouch.. I don't think you can buy just the housing (even though the sensor is removable). May as well get a JoeZ pipe.

that is what mine done ( but worse ) I used a heat gun to get it back into shape.....now I dont tighten it down like I did to cause that ( and nine happened on the bottom nearest motor ) was hard to see until I took it off

welp....twas the MAF...they said I needed a new one....that was my intuition...anyone have any suggestions on which one to buy? Which MAF sensors are compatible to a 2010 ISF?

LOL the dealer wanted $545.00 for a new MAF sensor...maybe if the owners daughter blows me too for that price lol.

will any Toyota/lexus MAF fit?

A MAF that is working doesn't suddenly go bad. Somebody messed it up. Did they inspect your air filter when they looked at it? It wouldn't take much for someone with little skill to screw up the MAF while the box is open.
