Little background about my Accord. Bought it last week, love the thing.
Has a few minor problems, but nothing I usually can't handle. Squealing belt from being loose, idle surges at the slightest touch of throttle and will keep surging if I'm going about 40MPH in 5th, thus I have automatic cruise control. So fun. Gonna clean it and a few other things. May even have to replace the IACV. No biggie.

Main problem right now is that I can't do the simple task of removing my PS Pump in order to tighten my serpentine belt.
As you can see.... There isn't a nut to even loosen.
The MAP sensor is another similar story.
I don't know what I'm even looking at.
Extra photo for those who may spot an issue.

 

That's not your map sensor. That's your TPS sensor.


Your map sensor seems to be inside that black plastic box with all the hoses going to it. Follow the #21 hose, that should be it.

 

Okay, cool,thanks for the tip. Have any knowledge about what's keeping the tps in place tho?

 

Are you trying to swap out your TPS sensor?

I think you have to cut a slit in it with a dremel and unscrew it out.

Also if you're doing this by yourself, dont do it, unless you know how to recalibrate your new TPS.

 

Na, I'm mostly trying to tighten my s belt. But I either don't know what I'm doing or something is different than most guides. Or both.

 

Next to the ground in the first picture. That big shiny circle at the pivot point. That has to be where you adjust the tension. The third picture shows clearly that there isn't anything that can be tightened or loosened on the other side of the pivot. It's hard to tell by the picture but it looks like the bolt head broke off and someone tried drilling it out but didn't finish. I'm partially going by the set-up in my 94 accord. Its similar but the pump and bracket in my car are different so get another opinion before digging out the bolt extractors.

 

Alright, thanks. Gonna have to look around to see if A: It's possible to loosen and adjust the S-Belt without moving the PS-Pump and B: What tools I need exactly.
If anyone needs pics for reference, just ask.

 

it been a while since i worked on a cb but if you dont have adjusting bolts to your ps pump loosen the mounting bolts use a pry bar and pry it upwards be careful not to damage anything and not to pry too hard over tightening leads to more issues, tighten your mounting bolts while prying your pump upwards

the little bolts holding your tps in place that look like rivets are the bolts, the bolts themselves are breakaway heads so the bolt head breaks off at a certain torque spec, comes this way from the factory so not to be tampered with after being set

its easier to pull the throttle body off if your gonna attempt to replace it instead of using a dremel i used a grinder to make it go by faster

the surging idle can be a multitude of things like vacuum leak,tps,map,iacv,fitv,egr, air bubbles in the coolant system and a few other things.

is your check engine light on? if it is you'll wanna know what code its throwing there's videos on youtube that will show you how to pull the codes if your CEL is on for obd1 and obd0 Eric the Car Guy's videos are pretty thorough and shows step by step

 

Alright, just for anyone's future reference that may have a setup similar to mine.
Remove the Cruise Control module.
At least I'm pretty sure that's what it is. Circled in red. Just pop that off and be sure to have the right ratchet and sockets to reach. But it's dooable.
Only problem now is that my A/C isn't working and my fuses are fine after doing this. So... Yeah.

 

So, for the TPS, I got a reading of 4.9V/0.45V Open/Close.
Is that within range? Or could that cause my surging?
My IACV is opening and repeats in a surging fashion consistently when A/C is on. It will surge when I push the throttle down almost any amount. As well as the fact that it will surge when I have unplugged the IACV. Basically does the same thing with it plugged in or not. Kinda weird. May not be the IACV.
Still having fun trouble shooting. Haha.

 

The IACV shouldn't have anything to do with the AC. It's likely a ground that needs cleaning. A loose or corroded ground will restrIct the amount of current moving through a circuit. Turning the AC on might be pulling enough current to cause the emc to be underpowered. I don't know if that can cause the IACV to act erratically but it's not difficult to check. It would be the usual suspect, the thermostat ground.

Speaking of the thermostat, your cooling system is a direct link between the AC and engine surge. Air bubbles in your coolant can cause engine surge, but the surging tends to go away when the engine gets up to temp. As for the AC link, ever noticed that your condenser and condenser fan are part of the radiator assembly? Even when the AC is off, the condenser and fan are used to help regulate your engines temp. I don't look at the engine cooling system and the climate control systems as being separate systems anymore.

 

Ya, not sure either. Question, does the iacv work even with it unplugged? I've detached it and it does the same thing. Idles bad of course, but still does that hissing sound as it opens.
And the ac stopped working for who knows reason. I'm gonna eventually see if it's just low on refrigerant after I check grounds. It all happened after I unbolted my cruise control and tightened my serpentine belt. So maybe I did something while in there.
Are we able to link videos? YouTube? I could go look at the rules, but I'm out and about on my phone. Haha

 

If it idles bad with it unplugged then you have a vacuum leak somewhere or the IAC is stuck open or failed in the open position. The IAC valve is naturally in the closed position when it is unplugged.

The A/C and cruise are connected to the same circuit. Might want to check that when you unbolted the cruise, you didn't loosen a wire or two. Also check your fuses.

 

Fuses are good. Unplugging the iacv doesn't immediately make it run badly. But if I give it throttle it sticks open and sorta chugs till I wiggle it enough to close again. Couldn't hurt to take it off and clean it, just gotta Google it. Should save to buy a new one tho. Haha

 

If you look in the FAQ there is a good write up on cleaning the IAC and FIT valves as well as cleaning the throttle body and EGR ports. If this maintenance hasn't been done, it is a must. Just make sure to use new gasket material and all surfaces are clean of all debris.
