Ok, so my 914 has really been pissing me off lately. with the cold weather, the car will nearly NOT start. i will end up using the entire battery to start it, but in warmer conditions, it starts easier. once it gets going, its really nice and smooth.
could it be the cold start valve? if so, where is it, and how many are there? (IMG:style_emoticons/default/huh.gif) also, will installing a popcharger, for example a K&N filter, improve performance at all, over the stock oil bath i have now? if so, by how much? all replys are appreciated, thanks |

can some one tell me exactly what the cold start valve does? or rather what is does differently from the AAR? Based on OAT, the thermotime switch may send a signal to open the "5th" injector on a cold startup .... I forget at below which temperature the thermotime switch becomes "active". It is extra fuel for cold starts ... a richer mixture much like a choke richens the mixture. The AAR only supplies extra filtered air on startup for a "fast idle" condition until there is enough heat in the engine to run smoothly. The cold start injector is very near the AAR on a 1.7. It is attached to the plenum with screws, has an electrical connector and fuel lines going to it. Trace your fuel lines and you will find it. And, the next $20 you run into ..... buy the manual. |
