I have been trying to figure this out but just can't...
Well this is whats going on when Im drivin if I use the trip-tronic and hold it in second before VTEC kicks in and once I punch it the check engine light will blink for a little bit then disappear. Has anyone else's done this?? I need to find out if something is wrong with my car anyone help... Thanks!!

 

you might want to go to your local autozone and get the codes read.. then for sure we can find out whats wrong with your car.

 

Does teh light stay on or just flash?

 

thats the tricky part there is no code and it just flashes and then goes away

 

Ive seen that a few times with my old motor and with the new when i got tire spin as well. It will flash a few times, but it wont store any codes.

 

is it something normal or is something wrong with the ride? Im drivin like a damn granny because im afraid somethin is gonna f'up if I put too much acceleration....

 

I have the same issue. When I'm in second gear and have the RPMs above 5K for more than 2 - 3 seconds, my check engine light flashes for 5 - 10 seconds. The computer spits out misfire codes. My dealer says I'm not supposed to drive the car like that... The owners manual basically says that as long as I don't red line, I'm fine. Service advisors response 'I know, but you need to baby your TL' I do, but sometimes I feel the need for speed!

 

Ive never did any thing to mine in 200k miles when it occasionally did that.

 

i had somthing like this happen to me and it turned out that i needed new coil packs.

 

After you replaced the coil packs was there any difference? Or did it run the same just with no engine light....

 

DOes yours run differently now?

 

Is seems a little slower but I did do the whole seafoam process (oil, gas, and vacuum line) but I haven't changed my spark plugs yet and haven't changed my oil but im not sure if that would affect anything with the engine light blinkin. It does it rarely but I do notice that I lost torque or so it seems.

 

Change your plugs and change your oil and see if it happens again. There is no need to drive like a granny.

 

Well changed my oil with Mobile 1 Full synthetic and replaced plugs to NGK Iridiums and damn that cost me alot for that stuff but so far no engine light and car seems like all the power is back my old plugs were pretty bad but well soon see if the stupid engine light comes back

 

Hopefully it was just a bad plug

 

IDK what u got...never has happened to me when in tiptronic or ever?...
When u find out..post it..

 

I know this is a old thread but I was wondering if anyone has solved this.

This has happened twice to me. Once in August after my seafoam, oil change, and NGK Iridium spark plugs change. I went on a spirited ride and once I got on the highway, I was on tiptronic and went from third to second and stepped on the gas like half way. Once I hit vtec, the CEL started flashing so i shifted up to a regular rpm range and it flashed and went away. After that, I never got a CEL light ever. Even when I tested my transmission and stepped on it completely while going 25mph, the tranny just downshifted smoothly and went with no problems.

And it happened again today, I just got on the highway and I shifted from third to second. I stepped on it lightly and once it hit vtec, the CEL started flashing so I upshifted again and it went away.

I guess it has something to do with being in tiptronic and hitting vtec in 2nd gear. My oil level is near the upper mark.

 

make sure your plugs are properly gapped

 

They should be because I bought them pre-gapped from Advance Auto Parts. Of course it could be pre-gapped wrong but I think this problem only occurs when in tip-tronic and in 2nd gear.

I was on D5 today and when I stepped on the gas, it downshifted to 2nd gear and redlined fine with no CEL or anything and it shifted smoothly.

 

Misfire. Bad plug(s) and/or coil(s). You'll have P1399 stored as a pending code if you read the DTC after it happens (but before turning the car off).
