Interesting issue - I have searched through the forums but did not see one issue that was exactly like the issue I am experiencing and it may not even be an issue at all but the computer doing exactly what it is designed to do.
The car has 94K miles - I am the second owner. Since I purchased the car - I have driven it approx. 3500 miles - 95% of these miles on the interstate at 65 to 75 MPH daily. The car is stone stock - no changes at all and I always run 93 octane gas. The engine performs excellent 99% of the time. Accelerates well, and maintains on cruise control 70 mph no problem. What is puzzling is when I have to accelerate to 80 to pass another car - maybe a quick burst that may last 15 to 30 seconds.... the first acceleration pass - all is good... however - if within a few minutes - I need to accelerate again - I do not just "punch it" but feed the power in slowly... the engine will fall flat and the "reduced power" light will start flashing. I have to reduce speed, and withing 30 seconds or a minute the light will stop flashing and normal engine performance will return. I do realize the reduction in the power output is a safety measure - too hot, low oil pressure, etc. of which these conditions are not existing. This is annoying as I have had to shut down and fall back in line on the interstate as I cannot pass the intended vehicle ahead of me.
Now - there are no check engine codes. I have a decent piece of equipment to scan for codes - no codes present.
Oil is fresh, air filter is good, etc, I would appreciate any information as the issue or non-issue if it actually is doing the right thing.
Since this car still has the original plastic LIM gasket - cold it be leaking Dex Cool into the intake and affecting the the engine under hard acceleration?
