GTI Help

[tncad]

Hi all. I just picked up a cuople of days ago a 1984 GTI that had been sitting for 2 years in a metal building/barn. Couldn't believe that it started and I drove it home. But here is the real problem, the fuel injection is trashed. It runs, but extremely rough, extremely hard to start, won't idle and I can't get this worked out. So, I am thinking about converting it to a Weber carb. I put fresh gas in it with fuel treatment and replced the fuel filter but still a no go. I think the carb conversion and new fuel lines will help this problem go away.
Has anybody done this and if so is it the best thing to do.
I really can't afford the Fi parts so I think this is the best thing for it.
Any thoughts or input is greatly appreciated.
Thanks
Scott

Is that CIS F.I system?

In General:
The fuel control system uses a measured fuel rate with respect to the "gas pedal". The gas pedal is an "AIR" control pedal because you are increasing the air into the system and the fuel mixture / Air volume is controlled by the injection "computer" . Have you looked at the throttle body and the air control "box"? You can take measurements at the components level and see if something is out of tolerance. Get the Bentley service manual for that car and it could save you $$$ and plenty of time..

I would think changing all that to carburetor would require a lot of work and would be quite a hassle to get that all working with respect to each cylinder attachment and fuel measurements.

Thanks for the reply. I went ahead and converted it. It does run alot better. the only thing to straighten out is the carb "cooking" when its hot outside and you have been running it. It only does it every now and then when the thing is shut off. And I even put the spacers on the manifold. Putting a dual downpipe exhuast on it and then a high flow muffler. Just trying to get some flow to it. I used a Weber progressive 2 barrel carb. The next thing is a transmission upgrade and new clutch.
