I just put an adapter and cone filter on my 1994 Supra na. I reset my ecu as described on MKIV.com. pulling the fuse.
But my car is running horrible now anyway. So I kept trying, keeping the fuse pulled longer, unplugging my battery, making sure my everything was plugged in correctly, and a million other combinations, but the thing won't budge.
I got it running ok for a day, but it just started running horrible again the next day. Is there a way to more thoroughly reset my ecu or anything!!?? Help!
Thanks [email protected]

Did you remove the honeycomb filter thing in front of the MAF? I did that when I installed a cone filter, and the car idled funny. Putting it back in place solved all the problems.

Unfortunately no,
but thanks for trying

There is a vacuum hose that plugs in front of the MAF. I forgot to plug it up when I changed plugs. My car would even hardly run.
The hose starts under the distributor cap if I am not mistaken, and goes to the intake piping right infront of the MAF. Does you aftermark intake provide a nipple to place the hose back on?
Your car should be the same as mine, I have a 95na.
Hope this helps, Let me know...
