Your car should still run fine but you'll get a cel for egr valve. Make sure it's for a 90 and not 91-94 for that they're different.

yeah sometimes when I am driving it, the check enigine light comes on, but it only comes on when I am going like 30mph in 4th gear and I push the gas all the way in, it starts going and the cel comes on. and when I let the gas go it goes away.

There's a way to fix that but I forgot how. You can pm "steve" about it if you don't get an answer here. He's great with ecu's and had helped me in the past.

In order to help I need the part number of the current ECU in the car and the code the ECU throws. You can read the code without a datalogger. I use a cheap 12v piezo buzzer for radio shack and two microclips. The positive lead goes to pin 1 on the DLC.

I hope you still have the MD128625 ECU. That is a '90 ECU, contrary to the information you received in this thread http://www.dsmtuners.com/forums/showthread.php?t=160613

Steve, according to vfaq, MD128625 seems to be a 92 and up ecu. But that part of the chart is a little confusing to me, can you clarified.

 

[steve]

You'll note that in the VFAQ chart both MD128625 and MD128623 are listed as High Line ECUs with no dates. That's because they couldn't figure out what a High Line car was.

I've deduced from CAPS that the '90 FWD Turbo cars were listed as High Line(Turbo) and '91-94 FWD Turbo cars listed as Premium Line(turbo). I show them as such on my ECU ID page. http://home.xnet.com/~steve/Auto/DSM/ECUID.html
