Well my car seems to run fine 0-60 when i have it floored, but then at about 65 it kicks down and drops to like 2000 rpm and wont get any higher??

 

Like the tranny is up-shifting way too soon or like the motor stops making power?

 

engine loses power

 

If you manually shift from OD to D, does the engine regain power?

If you temporarily disconnect the TCC connector, does the situation improve? You can try the same thing with the EGR solenoid, although you'll likely set an error code or two when you do it. You can clear those later, but it may help isolate the EGR.

 

I dont know if it regains power after I do that, but it also was running perfect tonight, then it died...my battery/alternator **** is kind of messed up also.

 

I mean it just all of the sudden died while i was in the process of whipping donuts(yeah that probably doesn't help) but my car doesn't seem to have any problems so i figured why not video tape some donuts then the **** died, and started right back up no problem then drove away with no trouble, ran perfect
