Newbie: rushed shift down, then 1st gear redline, then engine light flashes? Misfire?
2005 A/T, 70k miles, recalled engine in 2011...
OK, today I went to a bar, and during the trip I redlined the engine twice
The first time, I stop the car completely, then switch to manual then 1st gear redline. That was absolutely fine and a great fun. Then I switched to "D" and drove for a while.
Then I suddenly feel wanna redline the engine again. I was 40 MPH then, switched to "M"(when still driving), shifted down from 4th gear to 2nd. I felt reluctant to switch to 1st at that speed but still did. right after I shift down to 1st I immediately applied the throttle and redlined the engine. That's when I have the engine light came up and flashed couple times.
Then I speed down and switched to D, drove for a good while, It never came up again. Used manual again with slow or medium rpm, all gears, still good. but didnt redline.
So would this be an actual misfire? I have the spark plugs pretty new, but the coils may be old. Otherwise could this because my bad, like rushed shift down and immediate rev to redline?
Thanks a lot

if you wouldve tried, the gear display wouldve flashed to notify you that you cannot shift into that gear. if you had a flashing CEL its possible you did have a misfire shifting while in second gear or shifting to second gear. coils are a likely culprit. goodluck

thanks, It was 40 when I first started to shift down. I shifted to 2nd when it was probably 30-35. I didnt really look at the speedometer at that time. just felt the speed is a little too fast to shift to 1st.
I do have a plan to replace coils, wires and spark plugs at xmas(need to save for a while :=(). Hope the car keeps well until then. Anyway I ll go to autozone some time and get the code.

+1 theres no way you couldve shifted down at 40. my 4 speed auto wont shift to 1st over about 29~30mph, 2nd over about 68~70 mph (havent figured out 3rds limit yet.)

But my understanding is that the new AccessPort can eliminate that issue.

thats odd....cause i shift from third to fourth gear around 110 mph if i remember right... and i got sad that night when i found out theres a speed limiter on auto 8's i looked down and was like "whaaa no moar???? </3" and then i snapped out of it and immediately looked back up when i remembered how fast i was going. lol
