1988 mk1 1.8
New to the forum and the golf so I'm excited. I manage to take a red cabrio 88 1.8 which is in need of tlc off the hands of a client. Got it free as he was going to scrap it! Other than a huge clean, a new door handle, widow handle etc etc etc lol, I'm having issues with idle / acceleration.
So on a cold start it will hold idle for around 5 seconds and fade out. After a few starts it'll eventually hold idle. When warm it's drivable but seems to have little acceleration for a 1.8 and is very jumpy upto 2.5 revs. With higher revs it seems to smoothen out.
The local mechanic says it's the fuel regulator which seems about right, what do you guys think? I know they can sometimes be hard to find but he said he can get one in a few days.
Is there anything else that could be causing these problems?
Thanks in advance. Looking forward to working on her at the weekends.

anyway to start with go over all of the vacuum system carefully checking all the pipes and in the folds of the metering head boots. the pipes in particular look a bit ropey in places and it looks liek there may be a T piece open to air on the side of the metering head?
once all that is sorted give it a full ignition service with plugs, leads and cap + arm then have a read thru this thread:
you can ignore all the special 16v stuff such as isv etc, just concentrate on the basic kjet tests. also for the belt timing its the same pretty much except for the cam sprocket the punch mark is on the inside and lines up to the cylinder head surface with rocker cover and seal removed. For ignition timing this is set at idle with the vac line to dizzy disconnected and plugged, and for idle/co this is just done at idle. If you have a cat you need to find the sniffer port in the manifold, but I cant see any evidence of the extra wiring and control unit you need to run a cat and lambda probe?
after all that ideally you need to get some fuel pressure gauges hooked up to check the fuel pump, system and control pressures otherwise its a case of take your best guess and swap things till you stumble upon the problem
