Remeber those gauges you installed. Check the wiring, it may have burned and is rubbing and shorting out.

If the wires are ok, then disconnect the gauges.

 

Yea already did that. I have everything running through the cigarette lighter by the shifter. So it would have blown the Accessory Fuse if it was going bad.

 

Bump... I think my car is possibly doing the same thing

Redlined 3rd, bogged down got a ton of smoke (looks more slightly blue than white meaning oil i think )out the back, especially whenever In higher Rpms.

Here are the codes:

PCM U0073
IC U1900
EPS U1900
RKE U1900

Don't really know what to do from here, maybe just a computer hiccup??? Any help would be appreciated.

 

Okay lucky for me I have a workshop manual and looked up the codes...

Doesnt look good... L337 how did your car get fixed? Did you have a short?

Its important to note my Cobb AP is hunting 50% to try and communicate with my car (with the screen showing the gears turning)...
