Fuel loading up after warm-up

[gilsmak]

I have had my 84 GTI with 16v swap Down at a shop in Bloomington, IN for over a month now. Finally the owner has come to this conclusion:

The cylinders are loading up with fuel as it warms up and he doesn't know why.

Do any of you have any idea what this might be caused by? Its running CIS-E, all stock internals, a supposed new temp sensor, all new plugs and all new injectors.

Has anyone experienced this before? I can't tell if this guy is just sick of me wanting my car back and is giving up, or if this is a legitimate problem.

Any help would be greatly appreciated.

Thanks in advance,
-Josh

seen it before with a sticking piston inside the fuel distributor....

I actually had a spare fuel dist. Same thing with both. I am starting to lean towards the DPR or O2 sensor.

Is it spitting fuel put the exhaust!? Are the spark plugs completely fouled after 5 minutes? These things would happen before any fuel can puddle in the cylinders. If it is running rich, I'd probably look into another fuel distributor.
