IAC= Idle Air Control, it stands out like a big errection on the Throttle body on the front of it, If removed you will see two holes about an inch big, take it out and clean it with some brake cleaner or replace it with a new one, im not saying its the exact probleme but try there first and clean your MAF

MAF= Mass Air Flow, and this is right after the air filter, its black and cant miss it, if your looking that the throttle body you went to far

lol nice description

I know what the maf is but how should I clean it?

also how can I check if my O2 sensors are bad?

green95GT

you have to run a koeo/koer test then it should tell you if one of them is bad

pk222

will that work with having obd1?
I heard that obd1 doesent really help that much with finding problems?

pk222

by saying that I didnt mean to sound dumb just I have heard that obd1 doesent really help you that much unless you have a major problem

I had a similiar issue when i first got my 93. I didnt know what the hell was goin on. My dad told me to change the 02 sensors, so I did and it didnt do it anymore.

I might as well change them then It sounds like this can be a reason for a lot of problems

The slight popping is probably the smog pump. No big deal.
The ECM (computer) momentarily kicks up the rpms when yopu first push in the clutch to shift. This makes shifting smoother. Quite normal in most cases. It does sound like your IAC is sticking though. Also make sure that at idle, the TPS voltage output is under 1V. Preferably around .97v.

all right cool.
I'll clean the IAC tomarrow.
I know theres a how to thread on how to check the tps voltage but I forgot were it is and have been searching for it for a while because I was going to check it anyway can someone point me towards the thread on that? is it in articles?
