92 Si still revsfunny issue P28 ECU change
So, I did what I've been told to change the ECU. Release the neg off the battery and disconnect P06 ECU. WAIT. 5 min. I waited 10. Put P28 in. Connect the battery. Wait another 8 min. It took the car 10 times to start WITHOUT me hitting the gas. Little engine that could. Car fired up about 10th 11th 3 second turn over at a time. Hell yeah. All the haters across the street had to give it up. lol. Anyways.. After about 3 minutes, the up and down consistent rev occured. Like I was tapping the gas and releasing it. Now, I went to look for the IACV and found it. Gave it the best twist I could managel with the socket, and it wouldn't budge. I just sprayed some WD40 on it, and I'm not gonna try again until tomorrow morning. Not really down to break at bolt connected to the manifold. I got enough problems in my life. lol So.. other than the IACV, what else do you Guru's think I should check? You guys have been straight up cool for all of your advice. I'll do my best to do what I feel / know before asking so that I don't waste your time.
Thanks,

As far as your car is concerned, all i could say is keep trying with that IACV. It's either bad, dirty, or needs to just be adjusted. Also, you could have a vaccuum leak somewhere...have you checked for that? Try those two things, and see if it gets you anywhere. let us know dude.
do it EVER run normally? after warming up? If not, it's the IACV freaking out, like you said, or it's a vaccum leak. End of story.
If it does calm down after running, it's more likely a coolant issue or the cold idle valve needs to be cranked down. Not tough, but there isn't any info on how to do it. PM me if you need help with it.

Thanks for the help. So, here's my deal. My water pump is cracked to all hell. The car has been sitting since I got it, for the most part. The guy I got it from told me it was running hot, and kept putting water in it. All good. I've known him a long time, and I already knew the car had issues. So after the P28 ECU switch, I have the same reving. I took the IACV off and it looked like a screen covered with resin off of a bowl. (how I know this doesn' matter) lol After watching all the black drip out from spraying carb cleaner, I put it back on, with new air filter, and kept doing the rev. THAT's when I saw all the water I put in the radiator, pouring out where the water pump is. My main question, is how I get rid of all that white plaster of paris BS from all the stop leak he poured into it. First things first huh?
