Had the 914 out a couple times this weekend and noticed some hesitation while at light throttle cruising, say at like 25-30mph in 3rd.
I just recently did a valve adjustment and checked timing per the manual, had to clean up the points a little bit as one side had a little bit of a 'tit' starting to grow. Other than the hesitation it seems to be running well still, maybe a bit on the warmer side compared to what it used to be? (Also first time out this summer, ran it a few times this spring when it was nice and cool) But it has good power, and no audible changes in tone. What should I be checking first? Timing looked like it was right on the mark with vac line off and at about 3-3.5k rpm so I don't *think* that's the issue. |

914 Wiring Harnesses ![]() ![]() ![]() ![]() ![]() Group: Members Posts: 8,535 Joined: 7-January 03 From: San Ramon CA Member No.: 104 Region Association: None ![]() ![]() |
2.0L TPS have 5 poles (cavities), but only four wires, one cavity is empty.. All 914 D-Jet harnesses have only 4 wires at the TPS.
17 & 12 (on the TPS) are the contacts to switch on the idle circuit in the ECU, hence the need for continuity. The other two wires handle acceleration based enrichment. When the TPS is not at idle, then the sensors take control and not the ECU. Attached thumbnail(s) ![]() |
