Can you confirm that the CE light Kills power?

whell, here is what i have found this week. Last week i went to the track, and ran a 14.2, and a 14.3, both times missed a gear hard, and took a while to get it back into gear.

Now, at this point i Think somehow my egr valve sensor had the hack tape come off and tripped my CE light, which i dident see due to my white face gauges and bright sunlight.

I proceededd to make my 3rd run down the track, hit all the gears, and i achived a 14.4. plus the car was pinging like a toyota truck.

This week my car has been really slow, but i daily drive it, so i really dont get on it TOO much, but for some reason it felt slow, and i attributed it to heat.
I raced my brother on the highway with his 87' turbo supra, and i could barely pull on it....i was pissed....he laughed that his car cost 1,200.

SO, at coffee break on friday, i noticed my CE light was on, so i found the egr sensor was untaped, and fixed it (taped it half way in).

Now my car feels WAY WAY stronger.....like alot of power added, seems i got used to it being slow....But am i crazy? does the computer go into a "limp" mode?

I don't know much about the EGR system, but I can say the the light itself could no way in hell slow the car down.

I'm thinking if the sensor wasn't working right, the computer will revert to a backup table or it just gets confused and compensates for faulty readings in undesireable ways.

I dont know if the EGR creates a limp-home mode myself. Since it should not affect WOT performance in any way which could hurt much (if it malfunctions and is injecting inert gasses into the chambers at WOT, the car would run slow, but rich).

Then again, I am not a huge fan of doing the EGR thing w/o turning off the EGR function in the puter (the only way I would do it) so I dont know.....
Good question.
Good luck.

I ran the times in my sig with a check engine light. Mine has been on for 1-2 years, ever since I took my smog crap off. If your EGR sensor wasn't tricked, that could have been why, but probably not every check engine light.


About the heat, my car feels way slower during the day when its hot out. When night comes, it feels and runs way better.
