Re: really lopey idle

["Joshua Strait" <joshua13s@hotmail.com>]

I would say that a big part of the problem is your downpipe.  Before I 
had mine replaced my idle did a similar thing.  Any hole in the exhaust 
system is going to toy with your car's small brain.  once you replace 
your downpipe you will notice that the car feels a lot more solid and it 
should, for the most part, clear up your idle problem.
BTW- if you didn't already know, go with Techtonic Tuning's downpipe- 
it's literally half the price of VW's.

>Quick idle question for you guys, the car is an 87 1.8L 16v, when i 
start it up in the morning the idle is really bad, tach goes up and 
down, up and down.... almost like its gonna stall eventually.  Only 
thing i can think thats wrong with the car is the plugs cap and rotor 
haven't been replaced in a while, and i have a large hole in my downpipe 
(ye old flex coupling problem).  Could this be the problem, o2 sensor 
reading wrong due to the hole?
