Ok so i need some help, as to what can cause my slow acceleration.
So i have a b16 into ef hatch, obd-0. My ignition timing is set to 16*.
Only code i throw is tps, ive dont everything i can do to fix this code but it doesent go away.
Also when its kinda cold my car stumbles a little to turn on, when i rev the car a little it bogs down for a second then it revs.......

Mods.
intake/headers/exhaust/plug wires.

Any ideas?

Also how do i check CAM timing?

 

Have you tried replacing the TPS with a good one?

 

you need a new throttle body.

No he needs a new TPS sensor. Ours are usually rivet top screw on, but if you take a metal saw and saw 2 flat slips in each rivet, you can unscrew them using a flat head screw driver.

Replace your TPS and see if the code is cleared. You should always clear all the CEL before you start trying to figure out why your car isn't performing well. The TPS gives the ECU your throttle position information so it can adjust the fuel/timing accordingly IIRC.

Clear that code first.

 

should have been more clear.
its jdm so it has screws, anyways i did replace it, it does work like .5v close and 4.5-5v full throttle. Its also dialed in. Also i pull my ecu everynight so it gets reset daily, i also pulled the batt for 3 mins. The code will clear until i start the car then it pops up.
I cant seem to fix it pissing me off.
It has power and ground, so does the wires off the ecu.
I also tried a different ecu. STILL NOTHING!

 

Ok well my spark plug wires were wrong, so that helped a bit. But the tps is pissing me off.
