place it over the trumpet and it measures the vaccum drawn past the butterfly. the further open it is, the more vaccum. | |

they r jenvey 1ns. u mean by individual adjusters the 10mm nuts on top with allen key headed threads? on a normal valver the tps can be set up with a multimeter | |

the tps isnt set up its just loose and when it runs iv moved it till it runs better. there is only 1 adjustable screw to adjust the throttle position at idle | |

the throttles need to be perfectly balanced i.e the same amount of air passing by each butterfly, believe it or not literally 0.5mm difference can make a big difference! without them balanced it will run rich on some cylinders (too far closed) or lean on others (too far open). this also has a bearing on the tps. the tps (throttle position sensor) must be exact to run the engine properly, if it thinks the throttles are further open than they actually are then it will run rich and vice versa. to set the tps it neds to be done using a laptop and the relevant software. in a 2cm sweep of the tps it has over 100 load sites. if they are 1 out it will cause problems. | |

what do u mean by balance them? they have a linkage that connects the two sets 2gether i thought that was all they would need to actually make them open at the same time. i dont think the map is wrong coz the kid i got it off said it ran fine | |

i have an xe running throttle bodies and it hasnt run rite since i put it in. the compression is fine, its sparking, and its got fuel. it is over fueling on two cylinders. when i unplug the injector on 1 of the cylinders that is over fuelling it runs fine but when its plugged in the revs pick up 2 3k. two of the manifold pipes are hot but the other two are warm but not red hot. i think the fuel pressure regulator might need adjusting but im unsure of how 2 adjust it properly. any help would be great. which end of the fuel rail does the feed go to and does the fuel pressure reg go on the supply end or the return end. |
