I have a bad head temperature sensor on my 1974 1.8 914. I called Pelican Parts and they say they are not available. My car is just dumping fuel and I cant drive it until I get a new one.
Where can I find them? Thanks Dwayne |

Since I have your attention (IMG:style_emoticons/default/smile.gif) After putting in the CHT and adjusting the AFS wiper the car idled fine and stopped belching smoke. The next afternoon I put a timming light on it just to confirm advance before taking for a longer drive. Now the car idles around 600 rpm and the adjustment on the throttle body wont bring it up much at all and there is a bit of smoke again.
I did tear apart and reassemble the throttle body and I am thinking I may have the butterfly in a bit off. Full disclosure about a week ago I knew nothing about FI or L-Jet or even how to use a multimeter. Luckily I learn rapidly and was able to get it running again but lack of experience in a hindrance in knowing which spot to look. I did have some mean backfires the first day I worked on it so I guess that could have damaged something. If I am not successful with the throttle body, what else should I do? List so far. Multi vacuum tube leaks and tear in boot repaired. No more can be found. Timing correct. Valves correct. All 5 injectors pulled and left under pressure for several hours, no leaks. All 5 injectors have proper resistance. The 4 in the heads at 3 ohm and the cold start valve at 4 ohm. Fuel pump operates correctly and at proper pressure, a steady 36lbs. Full throttle switch operates properly. Aux air valve closes and re opens but I am not sure if it opens completely as I have never looked at another for comaprison. Timed thermal sensor is giving the proper resistance signal, and again cold start valve not squirting when it should not. The car accelerates properly and manual movement of the AFS sensor does not help idle. All I can think of is I did something a little off in the throttle body. I can manually open it slightly and it idles fine. If there were an idle screw I would be OK right now, theoretically. I can create a small vacuum leak and it idles right up. Any other thoughts out there for this rookie? Thanks |

Finally did my own timing and valve adjustment car runs like a top. Just my 2 cents. Car also uses much less oil,and no more smoke out the exhaust. |
