Hello, I have been lurking the forums for a while and I couldn't fin any info on this issue, I have a 04 TL with 60K miles on it, it's 6 speed M.T.

The other day I was running on the highway at 4th gear and still accelerating, when the engine was about at 4500~5000 rpm I felt how the engine stop accelerating for a moment (like when the engine cut off power over the red line), something similar, the check engine light popped up. I keep driving with no changes at all, the gears engaged normally, the throttle felt as usual. I was on the highway so there wasn't any autozone near for checking the codes.

Then I did the reset ecu algorithm (key on 2, gas to the floor 1 minute) and the check engine light went off and I didn't know what the problem was (silly me). Today happened the same thing but the check engine light only popped up for about 1 second and went off again, it lasted the time the throttle was off (like I said, 1 sec approx), like a blink.

Somebody knows what it could be? To me sounds like a sensor or something electric, the engine runs fine, all the gears engage as they should, etc.

The only thing broken on the car it's the engine torque damper, the engine shakes a little, but everything else it's ok.

Thanks for your help!

Check your oil level and pull the codes.

have the codes read.
the codes will tell you everything.

Hello, thanks for reply.

Well, I went to Autozone and since there is no check engine light on right now, there are no codes to pull .

This remind me Odyssey 2000, wait for the unit to fail again and see what was it. A mechanic friend of mine told me that it could be the fuel pump, since this only happens in high gears, the fuel consumption is higher and maybe the pump it's unable to push the required fuel pressure. It's a guess only.

Misfire wouldn't act like that, nor oil pressure, the vtec kicks in at 4600~ rpm as usual. It seems the only way it's to take highway and wait.

Any suggestions?

Thanks!

It could be the VTEC sensor or solenoid?

Did you actually plug the OBD reader in and check for codes? Or did the AZ tech say there wasn't any light so no codes....

Was your CEL flashing? Or did it come on and stay solid for a certain amount of time? The ECU reset you did isn't really an ECU reset, so it should not have deleted the code.

Definitely sounds like its misfiring... and if its as you described (sudden loss of acceleration) I'd start with something fuel related. Pull your plugs and look at them, too.

And what was/is your oil level at?

Sorry the long long delayed response. It was a dirty coil plug, I cleaned every one of them and the problem is gone, it was a misfire indeed thanks for the input.
