got a lexus sc300 love at first sight

no told me she was the devil

she gave me the ride of my life.

one week ago it started idle rough didn't think much of it but the next day
idle rough and hesitates so i replace the plugs and ran seafoam ran like new.

next day started the same thing so took it to toyota dealer they say rotor and plugs and wire are bad so i replaced them and reset the computer

ran even better.


today started it idle rough and when i gave it gas it bucked and died took 5 mins to get started and made it home.
now if you give it gas it bucks if you let off the gas it wont die
give it gas it dies

help please

 

Mass Air Flow Sensor is my guess. No check engine light I take it?

 

yep no check engine light

so is it the maf?

or tps?

dont have much money left

 

real good chance its the maf.my car did the same thing before i changed the maf

 

just cleaned my maf with crc and replaced the tps
hope that will fix it
dont have $450 for new maf


not that i do not believe you
just dont want to spend that much unless last resort

 

I got one for like 80 or 100 from aliga here. but what made my MAF issue much much worse was attempting to clean it

 

okay i put every back on but now it wont start
now what?

 

new maf ... uh vac leak?

 

fixed it coil wire was cut by fan replaced and started

and the tps fixed it
