VN Engine Tuning,can i do it myself???

[paultttt74]

Have a S2 3.8 and wondering if it is possible to tune myself?
It is running rough and feels mising at idle but has no issues with power and take off!
Seems to be running on 5 cyl at idle and when i stop at lights then is fine when running.
Is there a way to tune it without going to a mech?
Thanks in advance.

Well you can start with all the things that usually cause those issues:

1. Leads
2. Plugs
3. IAC valve
4. Blocked TB
5. Reset you ECU
6. Coil PAcks
7. DFI Module
8. Fuel Filter

try those and see whats you car runs like.
