1G Engine surging

[TKA]

Any help would be appreciated. I have a one owner 91 Eagle Talon TSI. The problem is the engine surges between about 700 rpm to 1500rpm. This used to stop once the engine was warmed up but now it does it all the time. Thank you, Kim

I was going through something similar recently. Here's a link to my post. It even includes what ended up being my issue. It should give you some ideas as to what to check.
