It's been driving me crazy for the longest time. When I drive my car and it's cold, it's drives great... after about 10 minutes (minutes after it goes into Closed Loop), it starts to feel sluggish. The longer I drive the less power it feels like there is.

BLM's are not bottoming out (they're around 115 in Cell 6 which is where most my driving happens.)

The Coil has been replaced, the Opti is the original (but I have problems believing the opti is affected by heat), Temps on the car are cool, so it's not overheating, the wires are about a year old, it's a CC305 Cam... anything else you need to know I'd be happy to supply.

 

Man, sounds like the coil or module acting up or even worse, the OPTI? when i replaced my coil the car didnt want to start right up and had stumbling problems so i replaced the module also, well after all of this the car after warming up stumbled in the low rpm range so your problem could be the opti (do as many tests as you can). Good luck!

 

The module would start to act differently once the car warms up?

 

Anyone have any other idea's? (or an answer about the module question).

 

get auto tap. It will help you out a lot when problems arise
