go to autozone or the like and get the codes pulled......then go from there...... flashing CEL usually means a misfire IIRC

drive your car directly to a reputable mechanic, better yet put it on a flatbed trailer, i would not drive 1 mile with my car acting like that.

It's broken. I will buy it for $5.
If you have nothing helpful to add that might help this guy, please don't bother to post.

Can't rev it past 4000 rpms? Don't launch control systems do that?

Why don't you try posting ALL of your engine/performance modifications........

Seriously, if he's saying it acts like the redline is at 4000 rpm, it's probably "bouncing" like it's a rev limiter or something - which is exactly what launch control on the AP does right? And I think that'll consume a lot of gas and throw a CEL if the car isn't tuned to accept the launch control- but I don't know too much about it.

+1 on posting all your mods.

...or the car is in limp mode or hitting a fuel cut.This could also be the ECU protecting the motor.

Is your vehicle modded? If so, when did it happen? Did you race it, modify it some more etc. -- can you pinpoint when it started to happen. In addition, what aftermarket - if any - ecu are you using?

Also, definitely access the codes that the ecu is throwing and check the forum stickies for the description.

Forgot to ask what your boost is doing during all this.
