Have I killed my STI? Check engine light, engine stutter at high revs
 

Hi all,

Does anyone have any experience of the "Check Engine" light on a 1998 STI?

I was in 5th gear going 140km/h and pushed my foot down hard as I saw another car coming in my rear view fast and the middle lane was full, anyway the engine stuttered and the "check engine" light came on.

I tried it in 4th gear and again if I pressed the accelerator down too hard at ~4000rpm I got the engine stutter.

Had no choice but to continue home ~300miles but hoping I havent killed the engine, does anyone know why the car engine is stuttering at increased acceleration, at high revs? And why the light is on?

What does the Check Engine light even mean?

Thanks for any help on this.

edit also on a side note it it legal that my speedo is in km/h i have no idea how fast i am going lol

Its in limp mode

Check engine light means a fault in a sensor, get a diagnostic obd reader and check what fault code it has, as jay says its in limp mode as its protecting the engine from what ever fault it has i presume its an import being driven hard on insufficient fuel and seen det

thanks for replies, thats good news!

yes its an import, had a full tank of v-power and was keeping it at 140km/h ~4000rpm the entire journey, not sure if thats driving hard.

will just live with it for now, dont have funds for diagnostics etc etc just wanted to be sure i didnt destroy the engine somehow!

oh it has a slight inlet manifold leak, could that cause an error?

but anyway thanks again!

I wouldn't drive it until you know what the fault is or you may end up with a damaged engine, you don't actually know how bad it is yet.

I'd at least get it to the garage for a diagnosis, shouldn't cost much and then you at least know what you're dealing with.

I'd also crawl off boost to the garage.

A inlet leak will be causing it to run very lean id park it up until funds can fix it, a gasket is a few quid an engine is a few grand

ok, thanks all!

Does it not have the green plugs under the dash?
