Items noted 1:Using Dave Darling's diagram the line coming off the throttle body to the cap side port of the vacuum advance unit is plugged with a screw and not connected to the vacuum advance unit shown in top of picture. Does this line need to be connected to the cap side port of the vacuum advance unit? 2: The line from the back of the vacuum advance line is omited because the car is a 74 and does not have a port on the throttle body. |

the vaccum hoses were a mess, hookup wise. we replaced them and put them on in the fashioned as outlined in george's diagram. found it in a search. problem persists. jack and i were brainstorming. a few more details came to light, and we may have solved the problem.
the car is hard to start. when it does it's straight to 3k+ with the throttle plate in the fully closed position. the fuel pump runs continously when the key is turned to the first position. not 5 seconds and off. jack told me the car backfired just before the idle issue. "stack (thru the tb) or out the muffler?". back up thru the tb possibly resulting in damage to the TPS or it was jammed out of it's proper setting. our guess is the ecu is seeing a signal for near or wide open throttle. he came by my place after i had left and picked up a TPS and a harness plug end that had been modified with 2 test leads. he'll test the TPS settings and recal it, replacing if ness. it was a good learning experience for the both of us. time well spent. brad ander's site was extremely informative. k |
