New to the Forum - 73 1.7L FI, questions about running rough Options

[tadink]

There are a few things that are just out of site that might explain a lot

Can you take another picture that would show that which is immediately below the frame of the current picture #2. That is where the MPS and the decel valve are. Just outboard of the intake runners.

couple more photo's - one from each side....

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.

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.

Clean it up, replace all vacume lines, check AAR, check MPS, put on air box, change oil, change fuel and do a basic tune up! It is hard to help you until the basics have been ruled out!

Start with one thing on the list and continue down the list! When you hit a wall ask us for more details about that item/issue and we will inundate you with information on how to procede, getting you to the next item on your list!

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)

Gotta agree Andy! 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.

thanks guys - keep talking me off the ledge. wow, a cleaned up area looks that good? 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....
