Check oil level

Do ecu error code test and see what shows

have you recently revved it over 9000?

i baught the ar like this week and noticed this lately so he couldve, i topped up my oil and i hit higher rev than i cpould , but yeh im preety noob at cars

[connorling]

had that problem before, my exhaust was chocking the engine, the ECU turns to Limp mode.

check if the exhaust is in good condition

Is the temp gauge sitting just below middle when warmed up?

Does it start and drive fine besides when vtec?

[erfanau123]

yeh everythings fine just the vtec, feels like having a rev limiter

[erfanau123]

it goes on limp mode and doesn't go over 4000 revs. I have a hondata s200 ecu sitting in my car and my stock ecu is connected. I hav
ust bought the car and haven't restarted the ecu by disconnecting the battery due to the immobilizer.

Quite a few red lights on your dash. Get the codes read.
