Vehicle sputtering under hard acceleration
Vehicle sputtering under hard acceleration
Hey guys, ive recently noticed that when I accelerate really hard on my vehicle it will completely stall out at 40mph. Once i let off the gas and begin accelerating again all is good. However the car will not enable me to just step on when without stalling out. Anybody else
ever experience this?
ever experience this?
MAF sensor, Fuel Pressure(doubtfull), or dirt in the throttle body cause bad response to some of the sensors there
experienced in my 240. MAF sensor shorted out the first time. and the second time I broke a little piece not thinking it did anything but did lol
I could be wrong since its a Lexus but I always check the MAF and throttle body first since its happened to me before.

You need a proper scanner otherwise you're just making guesses, even with a proper scanner it's a lot of guessing. You need to monitor your fuel trims to see if something goes noticeably out of whack at certain engine loads.

ok, so i cleaned my throttle body about 10k ago. And I did that pretty thoroughly. I just cleaned my maf sensor today, but still have the same issue. I havent reset the ecu yet, but will give it a shot and report back. I hooked it up
to a reader and looked a fuel trim etc and everything looked good.
