Hey all - Please allow me to introduce myself and I'll post some pix as soon as I can. I'm a longtime PCA member and have restored a 67 911 that is still in the family....now I've gone an purchased a 73 914 1.7L Fuel Injected car in the Bay Area. It has been sitting for a bit, does not have appreciable rust, and seems in generally good shape apart from some mostly minor issues.
Question - after having been sitting for 6+ months, she fired up and ran - but a bit rough. No engine noise or knocks, but the idle is rough, it stalls at low rpms, and is pretty rough except under a good amount of throttle. I'm thinking dirty injectors at least - what is the best course of action from here? options - add injector cleaner, good gas, run the bee-jesus out of her option2 - get the thing to the mechanic and let him sort it out option3 - ???? your help and guidance is appreciated - I've had great success with the lads on the Pelican Parts 911 board, and you all seem quite helpful as well as I've read thru the posts on this board. Hope to be able to contribute as well as learn... best tom |

I don't see your MPS anywhere? And no air filter? (IMG:style_emoticons/default/confused24.gif)
Some of them "plugged" hoses should be going to the air filter. Also, that looks like the wrong fuel hose and most certainly the wrong hose-clamps. That is an engine fire waiting to happen. (IMG:style_emoticons/default/blink.gif) |

That whole area is a dogs breakfast. Not only what you pointed out on the fuel hose but is that actually the fuel rail hanging in mid air with long sections running to the injectors? and one of those hoses is routed through the MPS bracket? The MPS has to be around somewhere. DJet won't run without it. There is something hidden below the decel valve but it sure doesn't look like an MPS. TD someone has really done a number on this car. You really need to sort it out before you go running that engine. There are enough folks here to help you through it and it won't be hard or terribly expensive. But it needs to be done. Here is what that area should look like (the leaf is optional) The decel valve is the small one on top and the MPS is the big one below. You can just see where the fuel rail goes. It is peaking out from under the left side of the mps. |

No wonder I'm covered in grime every time I think about doing anything out there......ok, new hoses, new fuel lines. Got it. I posted another question about what inventory to purchase of hoses and fuel lines, I'm sure someone has done this once or twice already. How many meters of each type of hose? we'll get there.... td |
