idk anywhere there cul;d possibly be a boost leak tho...when i finished replacing the headgasket it was running liek this, and i was getting a code 41 which is throttle position sensor signal

Japanese supra tt · 06-09-2007, 02:41 PM

Id check all the hoses and anything rubber that could be torn or cracked just in case.
but since your gettin a code 41, its gotta be the TPS, but you never know, those pesky hoses.

i dunno man, thats all i got.

good luck with your problem though mate

and its not a bogged down feeling, once my car hits around 2k rpm it just dies, until i shift or until the revs drop. and then gets power right away again, and idk if its a boost leak because the car will start to boost...but then due to the fuel cut i cant rlly see it boost n e more

Japanese supra tt · 06-09-2007, 02:43 PM

oh dam well its gotta be something to do with the TPS.
hmmm

you're hitting fuel cut very early, does it blow alot of black smoke out the exhaust? how does it idle?

When I had to adjust my TPS a short while back I found that using a hacksaw blade was a good thickness to put between the throttle and stopper. Then using the Ohm meter setting the TPS to any reading that wasn't 0 or 1. NOTE: It was hard for me to get it to the specs according to my Toyota OEM repair manual. But the car drives better now. Maybe do that simple test to see if your TPS is causing the fuel cut. I was ready to buy a new TPS too...but I'm sure like mine yours is still okay. I'm running on 250,000+ miles.
