I have my jdm h22a and it was running great I had a new fuel line put on recently and I have been running with a Vafc 2 --- the car will sometimes jump around and miss idle I believe it to be in the vafc wiring to the ecu but I do not know--- so I pulled the wiring out and played around with it a bit and the car seemed to run fine for a while ---- then I hop in it today and the car feels like it wants to stall and runs like sheat I do a check engine light check (trip the little blue plug and the cel just stays on and does nothing no codes....
but what could be causing this I believe it to be somewhere in the vafc -- since it will do it occational the tps sensor will go all crazy and sheat like from 30 to 40 to zero and that is when my car runs like do crap --- anybody have any expereince or can help thanks

Check your plugs - they may be fouled?

did you try driving it without the vafc plugged in? Might help you isolate the problem.

no it finally threw a cel light code 7 tps sensor
so I am quessing that the tps went out

replaced the tps and the cel is now gone however the throttle positioning is still jumping all over the place when you drive it I am thinking that it is in the vafc wiring --
does anybody have a vafc wiring diagram that they could share with me I looked at apexis website and it is not there thanks
