Ok I just swapped in my LS vtec into my 92 civic HB CX..It came out of my 88 DX HB..I converted to OBD1 via dizzy and injectors...p72
set-up..B18A block..B16A1 head and intake..Hyrdo to cable set-up for tranny..P72
yes the knock sensor is hooked up and.
Here is the problem..
While driving at a constant speed between 2-3.5K rpm the car will chug, if you know what I mean? It will pop sounding come from the exhaust and not pull then out of no where it will pull then start feeling like it is missing again. Here is what I have done..
Change Plugs and Wires..(old used wires)
The TPS voltage is .59 which I beileve is too high?
I dont know what to do I am lost and getting tired of messing with it..Any help is greatly appericated..

 

i would adjust the tps first to see wha happens(.45 to 4.5), are you using a p72 ecu?

 

yeah bro I am going to mess with the TPS tomorrow. I am using a OBD1 P72. I have the Knock sensor wired to D3 and it is not throwing a code.

 

do that cause it sounds like a tps problem

 

has your tps ever been fucked with

 

yeah actually it has. It is a JDM TB so the adjusting screws are torq's and it looks as if it has been moved before. And also I did not remember this til last night but most of the sensor case is cracked..The part the wire goes on..Could it be fucked up and not throw a code?
