I hesitate, for good reason, to declare victory on that fucking Bronco idle problem but I MAY have finally fixed that cocksucker.
I just drove it for about twenty minutes to make sure it got good and warmed up, shut it off and restarted it several times in the process and didn’t seem to have any problems with the fucker hiccuping and then the idle wanting to run away anymore.
Earlier this week I blocked off the damn EGR valve. Of course that turned into a complete cluster fuck and what should have been a five fucking minute job, naturally turned into a two trip to the parts house, hour and a half long fiasco.
I bought a gasket last week and it didn’t quite look right to me but the kid said it was the only one listed for my rig with the 351W engine.
Sure as shit. I had a blanking plate made to fit the gasket and when I took he EGR valve loose to slide it and the gasket back behind it, the damn thing was too long.
Back to the parts house. They looked it up again and insisted it was the only gasket listed. Back to the house, take the fucking EGR valve OFF THE RIG, take it back up to the parts house and SHOW the dumb bastard that it was wrong.
OMG, what now?
The almighty computer is wrong!
I have no idea what to do!
The kid grabs the valve and disappears in the back for ten minutes.
he comes back with one that fits a fucking JEEP of all things.
It ain’t right but it will work. Then the guy I wanted to talk to in the first place comes out front from back in the warehouse so I snagged him. He knows Fords.
He him haws, looks it up, sure as shit it’s the only one listed, goes back and starts digging around in the computer. Maybe two fucking minutes, tops.
He yells in the back at the kid with a part number, a couple minutes later here he comes and low an behold, it’s the right one.
Fits an F-150 with a Straight 6.
The guy tells me to remember that, I’m thinking you fuckers need to update your data base but I’ll take it. Another dollar ten more of course, for a smaller gasket.
I finally put the damn thing back together and took it to work, better but still not right.
While I was there the first time, I also bought what I figured was the fix for this bastard all along and was just being a lazy bastard and not wanting to do.
A throttle position sensor.
Ayep, they ain’t no fun.
Ya gotta take some small cooling lines off, unhook the throttle cable and the transmission kick down cable, unhook the sensor, unbolt the entire fucking throttle body, take the bastard into the garage, put the fucker in a vise because it’s on the bottom of the throttle body of course, get an impact driver and in this case, a small torch, heat the fucking boss up where the screws thread in behind the sensor, slam it with an impact driver with a #2 Phillips bit in it until the damn screws break free and Then, take the two screws out.
You see, Ford, in their infinite wisdom, decided they did not want those two screws to come loose, EVER.
To make sure, they put some kind of wicked assed Loc Tite on them at the factory and as you can imagine, they have been in there for thirty fucking years now and absolutely refused to budge.
Even back in the day, you couldn’t just use a Phillips screw driver to break them loose, you were 100% guaranteed to strip the screw heads out if you insisted on trying.
After you finally get the motherfucker off and the new one on, you are supposed to do some Ford Magik and actually plug the thing into the vehicle harness while bolted to the throttle body, turn the key on and then while using your third hand, stick volt meter probes into the signal return wire, twist the sensor slightly until it reads ZERO volts and then tighten the screws up.
Yeah, fuck you. Ain’t happening.
I started the screws, twisted it until I was sure there was no spring tension on the sensor so it should be at zero and then tightened the fuckers up.
As per every shop manual in existence, installation is the reverse procedure of taking the fucker apart, other than cleaning and replacing the gasket.
Bullshit. While I had it off I cleaned a ton of black gunk out of the throttle body behind the throttle plates and got as far inside the intake plenum to do the same as I could. There is some seriously nasty shit in there.
I put it all back together, hooked up that damn idle speed solenoid, cleaned up a couple more grounds just for good measure, put the battery cable back on and crossed my fingers.
It started right up, smoked like a bitch because of all the carb cleaner in the plenum, had a slight misfire until it burned out and then settled right down to a nice, livable idle speed.
I ain’t trusting that fucker for nothing.
So I also noticed that there is a small piece of plastic broken off the throttle cable assembly and it seems just a bit sticky at full stop.
I lubed it up but am going to replace that next.
Like I said up top, I drove it good and hard for twenty minutes and the only issue seems to be the throttle cable not quite coming all the way back unless I tap the gas pedal real quick. Then the idle will come all the way down to 700 or so with it in gear. It wants to stick at about 900/1,000 otherwise. Combine that with a fucked up throttle sensor and there we go.
I am not going to put this episode in the WIN column until I get to drive it for a few days but I am certainly encouraged that I might have possibly finally fixed this cocksucker.
I would be very happy if that turns out to be the case.
Just FYI, I am going to be working twelve hour shifts again for a while starting tomorrow afternoon.
I’m going to be tired an especially grumpy for at least a week. Then right after Thanksgiving, do it again for another week.
I’ll post when I feel up to it.
I will update the status of the Bronco, good or bad, sometime in the next few days.
OK, I’m gonna go out on a limb here and say it’s fixed because it just passed the biggest test there is for the fucking thing.
before today, without fail, every single motherfucking time I had to sit behind someone at any kind of Drive Through, the bastard would suddenly rev way the fuck up out of the blue without warning.
I always had to have my foot on the brake hard to keep it from crawling up the ass of the car in front of me when it decided to do that.
I’m serious, every time.
I just got back from McDonalds at dinner time so the drive through was packed. I sat behind several cars waiting to get up to the window and it never even blipped like it was going to run away. No problem going or coming all the way home.
Nice and civilized like.
I don’t know how to act.
It ain’t like there aren’t several other issues waiting in line to get fixed but I would like to think I am finally done with this particular issue.
