Have you checked your timing?

x3kartoonx3

no but it was running fine in my da but i also had a b16 in it firs that i got off my brother also working fine in his hatch but it had the same problem it has now i thought it was timing so i put the ls in

I had the same issue when I installed my edelbrock manifold and throttle body....check tha tps denser cuz it has 2 hot wires one is a cons and other 1 is a 10-12 volt switch those wires and u should b good....hopes it helps

Mr. EG

The TPS never gets 12V. It operates as a Potentiometer. .5V at idle and 4.5 at WOT.

Mr. EG

I would check your wiring/ ECU to see if the wiring is ran correctly. What engine harness did you happen to use?

EK AL

Am sorry the senser has 3 wires 12v-ground-const.....swap tha 2 wires but don't miss with the ground wire....hope it helps

why would the wires be swapped? Do you have a check engine light on for anything? What injectors are you using? What ECU? Are you using a distributor adapter and ECU adapter? If everything was working fine in your DA its probably a wiring issue of some sort.

Some peole are rushing when doing a swap and they put that tps sener plug on backwards.....I've done it :^}

Are you talking about swapping the MAP and TPS sensor connectors?

im running obd2 injectors obd1 ls distributer with a step down obd1 ls ecu with a step down the obd1 alternator plug is added to the harness it came like that on all three harness i used the stock one then i got a ex one then i just bought another stock one i tried to get one thats not cut but the kid lied to me i tried switching the plugs on the tps with map but its not that

when i was searching it people had the same problem so i tried alot of things so far some where i read i could be the fuel pump or fuel filter could that be my problem ?

EK AL

Na I was talking about tha tps cuz I had that issue when I installed a 70mm mustang throttle body on the jg manifold and u hav to hard wire tha tps wires 2 tha tps wires on my harness and run a hose off of tha map senser 2 make everything work like stock

im running a stock ls throttle body i tried three of them same problem i made the distributor step down myself so i wouldnt have to cut anything but i tried a obd2 distributor from my cuzins hatch same thing

x3kartoonx3

i still havent been able to find out wats wrong with my car my friend said it could be my interior harness dose the interior harness have anything to do with my bogging problem

it seriously sounds like the wiring in the tps sensor ... i have a eg civic and when i swapped the jdm gsr in it i had alll kinds of problems with the tps sensor ... it would rev slow passsed 4500 but wide open it wouldnt it ... i would try and demount the tps sensor and remount it and calibrate it and make sure that your wiring to it is correct ...

ill try and see if its that do u think it could be my interior harness ?
