just got my car back on the road.
Now i'm running a ffim with a q45tb, tps adapter kit to work with the 7m tps.
Now when i pull off, as soon as it his 1500rpm to around 2000 the car feels like it just stops and if i floor it, it bucks a little and clears up.
It happens around 1500rpm.
No codes are shown.
Any idea what it could be?

My tps plug is a little broken (the piece where the plastic metal clip snaps into is broken on one side).
I don't think that could be the problem because the metal clip still locks in the tps.
I was thinking perhaps like a flat spot in the tps where it just does send off a voltage and then it kicks back in.
Any help would be appreciated.

Sparkplugs are brand new, it has lexus is 300 coils so i don't think it can be anything spark related.
Timing is dead on at 10 degrees.

I also had to hack up some of the linkages on the q45 to make it clear my hood when it opens.
Also, when i slam the tb shut (i.e. coming off the gas quickly), it usually bogs down when i'm driving.
Does this have anything to do with the tb closing too quickly?

Good luck man. The TPS owns me on my wife's car. I wish I lived closer to some of our electrical geniuses like JJ and a few other mods that we have here. They make it sound like it's easy, but it's not that easy for an unedumacated redneck...........:3d_frown:

lol.
I hear ya bro.
I think its the tps.
could be my afm (perhaps) because sometimes it will take a while to start, and i have to disconnect the battery and reconnect it sometimes, and tap the afm.
Mind you i've only started it like 5 times and it would start twice.
