My check-engine light is on (stock ECU), so I checked the codes. It was "EGR Switch - open or short circuit". But then I realized the EGR has been removed (just bought the car - woo-hoo). Can I get some help what to do?



Also, when I finally replace my ECU, will I lose some functions, such as error codes, AC, etc?

I have an egr you can have if you pay shipping. Other than that I couldn't tell you.

If the car is a 93 Cali spec car or a 94 or 95 then you have to have the EGR to keep the light from coming on. I heard of someone using a relay in it's place, but that sounds like a pain.

When you replace the ecu you normally won't lose any of the normal functions. Some ecus have a little trouble with the a/c and turbo control system(namingly haltech) but are remedied without much tribulation.

i did the relay it took all of five minutes and fixed the problem!! i drove around for months with damn light on. all you need is a relay and some wire. i dont have the directions for it any more, but if you look on the net you can find them. i will look around to see if i can find the directions for you. good luck and trust me you want to do this mod, is sooo easy you'll beat yourslef in the head if you dont try it.

Buy a Power FC. No need for EGR!

Thanks Sully. I will search for the instructions. I don't think I want to put one back in.



I don't know if my car was a Cali or not. I assume if the light is on it must have been? Do non-Cali's just have a block-off plate (I have one).



Yeah, I need a PFC bad. Plan on gettin' it next summer with a new intercooler and mid-pipe. Damn these Michigan winters!

the 93 federal cars have egr but no sensor

the 93 cali, and all of the 94's have egr with the sensor

95's have no egr at all

Do we really need that EGR. What happens if we do put a relay in it and how?

you dont need the egr, it only there to

1. make some beurocrat happy

2. break and cost you $200 every 13-24months

LOL! I wish i could eliminate mine? Do you still have yours on?
