Car issues again (Page 2/9)

Because it had a super rough idle, tested the IAC valve and no resistance or anything pulled it out and the mechanism was stuck open wouldnt adjust, hence the replacement.\
And I'm going tyhrough parts that change when the engine heats up, the IAC is one of those.
I also don't know where to get a scanner other than the one I have seen on the fiero store, and the car dosen't have a check engine light up, I know I'll still be able to check stuff without it but just thought that might be an important piece of info, Is there a scanner I can get off of amazon ?

I use WinALDL with an appropriate cable and ancient laptop. Works great.

Have a look at This post. Click on the link there to his website.

As Patrick instructed.....there is a link to the phonedawgz web page.

edit: listing the parts you have changed sounds great, but new parts are not as reliable as they used to be....

Buy a sawzall and cut the cat out and put a straight pipe in for now. You can buy
exhaust pipe and adapter pieces at any prts store. Your cat is a year older than mine and mine was plugged 14 years ago. Get a new high flow cat if it isnt plugged. They are not much money and better than the original.

Thanks I'll definitely give that a try and I'll pick up a cable as that seems like the easiest solution because from what I'm hearing it'll essentially tell me what's wrong even though it's not throwing codes correct?

That I don't know but if other people that have that equipment say it will work I would believe them. I just think you should do one thing at a time and not waste a bunch of money buying stuff you dont need. That being said, working diagnostic tools always come in handy sooner or later.

That's what I've been doing just one thing at a time and seeing if it fixes the issue, if it doesn't the part needed to be replaced anyways as most sensors are old, just trying to narrow it down so I can have it running well while I replace everything else 😂

ICMs fail in different ways. Some auto parts stores can stress test them. Autozone near me had a tester.
