2nd gen talon question

[Canadiancon]

Hey guys, im going to be buying a 97 talon awd, this is what the guy had to say

the car idels rough that is due to the new 14b turbo I put in it. It just needs a bit of tuneing. Its not ideling like crazy but it does change (it doesnt effect the driving and still has same amount of power),

Any one know why?? just some tuneing like he said??

Thanks

could be a whole lot of things causing that.

fuel pump replaced without doing the rewiring mod
bad head gasket
bad compression
bad 14b
bad airflow meter
bad tune

it's hard to diagnose it over the intarwebs.

if engine is old, it might just needs fuel system cleaning.

all the valves, piston, etc...are contaminated by carbon.

check your set screws, go to vfaq.com

and putting in a stock turbo shouldnt be making it idle weird unless its an ebay dud

check compression
