ok so i just got a pm6 and put it in my car after doing my mpfi swap not to long ago,and im only throwing a iac which isnt too bad just when its cold

but ok with the pm6 if i have wide open throttle,like fully,the car will bog down and feel like it has no throttle response at all,but if i take a slowly and floor it like3/4 it drives fine with no problems at all

any ideas what the problem could be

i have a pm5 map sensor which is my guess,but also maybe the ignition timing is off,or a possible vacum leak,but im clueless

like i said im only throwing code 14 no other ones at all

it didnt do this on a pr4 but it was dumping way to much gas so this is my only option,even if i get ran over trying to get on the interstate

Duuuuuuuuuuuuude. The Dual point Throttle position sensor is your problem! I wish you woulda told me that before. You can't use that sensor!

 

ummmmm nope it is a zc tps

the problem was on of the dual point plugs not sure the name but ya long story,fixeddddd

 

word

 

Check your wiring and make sure nothing came loose. My car sis the same thing you are describing and it ended up being the wiring came loose at the ecu. Could also be your tps. try another throttle body.

 

nothing was loose,just when i did my mpfi harness i cut off the electric aircontrol valve,instead of the purge control valve(dual point intake manifold)

so i just had to go back in and we wire it

so its fixed
