This may get long, I did a few searches and I am fairly confident I know that my fuel pump may have died, my iac is shot and needs to be replaced, and I need to do a mercon V switch, like now haha.
This is for my 93.
On the way to school today I was idling really rough and stalling at every red light (something I attributed to the IAC being bad after 120k?) unless I held it in neutral with the gas being pressed, or in park by itself ( it seems to stay warming up in park with no problems, just stalls in neutral or drive, weird) but whatever, I had an exam and I hopped on the highway figuring that by giving it constant gas I'll be fine....I wasn't.
I was trying to pass someone and I was going 55, when I gave it gas its almost like nothing happened, I floored it and it was barely accelerating. At this time I noticed a very slight shudder (probably my tc based on searches) similar to the shudder I'll get every once in a while on the highway at this speed. I was more concerned with the loss of power, so I pull over and it immediately stalls when I let off the gas. I didn't have time to waste so I had my little sister pick me up, now for the parts. I'll check fuel pressure and see if I can drive it home tonight after class, I'll have my mother following me. If it doesn't work out I'll have AAA tow it home. My fuel pressure was on the low side (32psi) a few months ago, but my tester from harbor freight also leaked a little, so that may be skewed. At the very least I'm prepared to buy a new fuel pump (it may have to be an advance auto parts unit) locally, and have a local mechanic do the pump (and 02 sensors while he's at it) locally.
But I've also read it could be related to the IAC and EGR valve. I didn't find much information as to testing the IAC besides unpluggging the brake booster line, which I'll do. What about the EGR? What are symptoms of one that doesn't work, how hard is it to replace, etc.
I was looking for a walkthrough on replacing the IAC/EGR, I wouldn't notice the egr by looking at it, and the iac is to the left of the throttle body down low, if anyone has any walkthroughs on this or tech articles, link me please.
Summary,
I should expect to have to replace the;
fuel pump
02s (if I have to replace fuel pump, have someone else do it at the same time)
iac
egr
what are the best options for picking these products up locally? advance? any particular brands to steer clear of, etc. I'm at school now and my mom is gonna go have it towed while I'm here so I'll be home around 10 to check things out a little further.
