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) |

(IMG:style_emoticons/default/blink.gif) Hi Steve - good eyes - the hoses are a bit of a spaghetti western for sure - and need to be replaced. I'm on that part of it.... the air filter was removed as I was sorting out what was there and what was not - I've replaced and started her up - ran pretty well, still some chop at mid throttle. Might be electronics - might be FI - hard to tell. certainly a work in progress - - - I'm thinking the MPS is underneath all that crap - electronics in, one hose out? also, where does the FI brain box live? Mine is just laying under the battery tray, not affixed to anything? If you had a pic of where it should be, that would help me find the right holes to put the thing back. where is the fuel filter? I'd like to replace, for sure. found a bunch of sketchy hose connections - and one rubber cap midway between what I think is the MPS and the throttle body. It was mostly corroded, seems to let pressure out but hold vacuum in? guessing. plugged the hole, is that bad? sigh - perhaps this is a bridge too far and maybe I should seek professional help? thanks for engaging on this, very appreciated. best td |

sigh - perhaps this is a bridge too far and maybe I should seek professional help? You just need to keep in mind that this car has not only been neglected but has had parts 'salvaged' from it over the years. Go slow, no telling what kind of DAPO ('dumb-arse previous owner') surprises might await you. And as the pic above demonstrates, some of those surprises have dire consequences. Just relax, you're in the right place. (IMG:style_emoticons/default/smile.gif) |
