Hi guys, I got a couple of questions.
First off, I am fairly new to 914s so I am not sure if this is normal. 1. I have a '74 with 2.0L fuel injected. I would say the car is well tuned as it starts instantly upon seeing the key in my hand, and it runs great. However, It is (in my opinion) a pig on gas. I don't think I am getting better tha 15 or 18 miles to the gallon combined driving street and highway. Is this normal? 2. After it's up to temperature it will not idle and it will stall. Some times it will not restart till the next day. Last time it stalled I thought it was out of gas, because that is how it behaved. I would turn the key, it would start instantly run for a second and stall again. This is keeping me from driving and enjoying the car. Any suggestions? All input is greatly appreciated. Bill. |

Hi guys,
I have not checked the valve adjustment in a while, and the car does not seem to run rich judging by the spark plugs and there is no smell of gas, 76-914, what do you mean did I check the cht? Thanks, Bill. |

....also, check your MPS (manifold pressure sensor)
a bad one could lead to rich running and bad mileage. I experienced the same issues your having at some point in my 914 ownership, and it was either the CHT or the MPS. and check everything else of course..... (IMG:style_emoticons/default/biggrin.gif) all this figuring out would be easier if you had someone from this site to lend you a hand....someone local to step you thru the process of checking stuff |
