What are you looking to get out of the car? do you want a race car or a reliable faster daily driver?

more of a reliable faster car,car really just needs some fine tuning,engine has been fully rebuilt and just run in,so now it just needs tweeking.just had the car smogged and they had to adjust the mixture to get it to pass,so now it just needs tweeking back.

Don't touch the mixture! If it has been rebuilt then advance the timing a little and you will get more go out of it. There are little things you can do to get more HP but in the end it's CIS. Depending on if the head is solid lifter or hydro will determine how much more you can get out of it. A solid lifter head revs higher but dealing with shimes and adjusting the valves is the suck. Hydro heads are great for the throw in a cam and drive it. Opening up the exhaust will make a good difference also. You can find headers for cheap most the time.
Is the motor all stock? what motor code is it?

motor is mostly stock,came out of another 84 gti.i have currently g grind cam,aftermarket headers,tt exhaust,high flow cat and magnaflow muffler.
my problem is when the engine is cold,she runs fine,i guess its getting a lot of fuel but when it gets warm and i guess the regulator kicks in ,she runs rough.i thought that she might need to be richer when warm,hench turn up the mixture but it makes no difference,i relly need to take it somwhere to adjust the timing and check other obviouse causes.
i am sure it would be a simple fix for someone with 8v knowledge but its finding someone.

This sounds like a vacuum leak, to me. When it's colder, it's getting a fatter mixture which masks the vac leak. When you're up to temp, the mixture leans out, back to what should be stoich - but the vac leak makes it lean and run like doo-doo.

I went through these same symptoms and vac leak elimination is the only thing that cured them. It was CIS-E, but the principle should hold for your CIS-lambda (I think that's the flavor you have...).

BTW, I know a guy named Patrick here in Livermore who is a MkI whiz... Not a shop, just a dubber. LMK if you're interested and I'll drop him a line and see about making an 'introduction'.

i was worried that it might be a vac leak,other people have said that it is a pain to find,once again i guess if you have done it before then it would be easy.by all means let your buddy know,i work in livermore,so it would be easy to hook up with him.
thanks

Vac leaks are the suck. I don't think it matters if you've tracked them down before, they still suck to find. Some are easy, but a bunch of them are sneaky bastards... Where do you work in Livermore?

Check your PM so I can coordinate an intro. I'll drop my bud a line and check his availability, too.
