Yes i searched, and nothing ever came up on a solution to it. (Go ahead try it)
I have a problem in 1st gear, it jerks/bucks like crazy i figured out how to work the clutch and gas around it but i want to fix the problem not avoid it.

I adjusted the TPS, read .47 idle 4.42 WOT, played around with a lot of different adjustments,. It's set at .49 Idle 4.50 WOT right now.
45 idle 4.40 WOT
.50 Idle 4.35 WOT
.65 Idle 4.50WOT

Even disconnected the TPS and it would still do the same problem, it started after i converted to MPFI, Car has brand new Clutch, Brand new Flywheel, Trans is 4spd no problems, no grinds pop-outs ect... shifts like butter.
Car runs perfectly besides this situation.

This happened on my old motor as well after the MPFI, (D15B1)
I have since swapped it with a JDM OBD-0 Carburated D15B and the problem persists.

What else could be causing the problem?

Oh, and before jackasses start posting dumb **** don't even bother i'll report it to the mods, i want to solve this problem to help others in the same situation. If you don't have anything positive to add, or atleast a possibility to the solution don't even post.

 

Mine does the same (d15b1) I just figured that's how it was.

 

Yeah, i did too at first but my buddy has a EF with a D15B and it doesn't do it. =/

 

mine use to do this on my old d15b2 motor with dpfi...i changed out the entire throttle body assembly with tps from efjones9 and the problem went away...!!!

 

Cool cool, i'll see if replacing the TB helps.
