update >> light show on my dash - dealer can't help....

Recurring problem..........
after dynoing a couple weeks ago (including pulling/replacing trac fuse), the MIL and trac lights came on.
I figured it was a loose fuse, etc., so I stopped, pulled trac fuse and ECU fuses and replaced them.
Lights went off and stayed off for a couple of days. Then they came back on.
This has happened a couple of times since.
Now, in addition to the MIL and trac light, the check engine light is on and the O/D light is blinking (it's an auto).
I took it to the dealer and he says he can't get a code - he blames it on the "aftermarket" mods. (I have K&N intake, EVC 4, Borla exhaust, boost gauge). Does this make ANY sense?
Is the dealer crazy - or me?
Any suggestions would be appreciated.......This is aggravating. :eek:

Well, if you want to get rid of te trac light and it's associated MIL, then unplug the trac computer next to the ECU (both connectors). This will allow disabling of the trac control without the flasing light or "!". Removal of just the trac fuse will cause the MIL.

For the check engine light, check the EGR hoses. These are the thin hoses that go to the modulator. They crack with age and will give you the MIL. Of course i'm assuming you have not done the EGR mod. It sounds like this may be an issue as the check engine light does not come on right away but only after a period of time.

Also, may want to run diag yourself by jumpering the diag port with a wire and reading the flashing light code(see mkiv.com for details).

Just some suggestions!! :)

Thanks Greg - are you psychic??
It turns out it probably is the EGR....
When I tried reading the code, it was kinda weird!!!
The MIL did NOT blink, but my check engine light DID blink (code=71).
I dunno what that was!!!
I'm gonna do the EGR mod (plate) and resistor and then clear the code. If the MIL returns after a few days, I guess something else is wrong.

Anybody know why the MIL didn't blink but the check engine light DID?

"71" is "EGR System Malfuction".

The engine light is the one that flashes the code, not the MIL. At least in my car, sounds like your's too :D.
