Prizes for working out what's wrong with my car

Car:
1999 Bora SE 2.0 8v (APK)

Mileage:
102K

symptoms:
erratic idle when cold.
misfiring between idle and 3-4k, intermittent at normal operating temperature but prominent when cold.
Excessive fuel consumption.

Can a mod please move this to the correct section?

I had the same thing with my golf mk4 gti what engine code is it? Mine did it I tried changing loads of stuff nothing worked!!! I narrowed it down to the fueling I was going to try a new fuel regulator

To start with it will need plugging in.
I can do this for you and give you the results and maybe cure it for you.
I am in littleport. 07791001385.
Try me.

I'd say maf or coil pack but wants a diagnostic scan

my money is on the air flow meter.

Depends what the prize is really

Fixed now.

Many thanks to Guy and his vadge-com and superior knowledge.

Misfire on cylinder 1 caused by crappy HT lead/spark plug connection. He also cleaned out my throttle body as well.

I cleaned my MAF in isopropyl today. Betty is running just lovely now.

I bet he did

Guy does know his stuff

sweet, mine's doin this. i've got a spare maf, and ordered a set of plugs n leads, hopefully that'll cure my prob

This is exactly what was wrong with my MK4 2.0 GTI.
Took it to Guy, he said it was a HT lead issue.

Went to Halfords 3 days later, fitted them with the help of Mr Sparrow, and it ran spot on.
HT leads and MAF sensors are the bane of the MK4 platform apparently.
