I cleaned the throttle body yesterday evening and filled a small t-shirt with goopey black carbon crap. I shot it back into the area too, not just that little silver blade. Don't know if I was supposed to...

After I reconnected the air filter and all (today) I started it up (hard to start) and warmed it, then throttled some. I can hear an air pressure noise in the front and the exhaust sounds like it's gargling.

See the YouTube video of the backend.
What did I do wrong? One of the MAF screws also broke on the way back in, but it is holding just fine (how do I get it out?)

What should I do?

Oh crap, man I feel horrible!
I could kick myself in the balls.
What'd I mess up?

All the sensors are connected and never were disconnected, I should add.

How much of that stuff did you spray back into the manifold?

Why didn't you take it to a garage that would service the whole top end of the motor. I did that on my last one and it came back running better than ever. It was a machine they hook up to the TB that deatomizes the upper engine.

How much of that stuff did you spray back into the manifold?

All the way in, I sprayed a fair amount. Maybe a bit much, but the noise in the front sounds as if it's spitting air out of the tube...?

OK, you should not have sprayed any in there. It is probably pooled there. Start the car and let it idle and get up to normal temp. The stuff should evaporate and burn off. Don't rev the engine or drive it till the gurgling stops and the engine runs normal. You don't want to take a chance of ingesting a slug of it an hydrolocking the engine.

The air noise might be air being sucked in between the MAF sensor and the TB if there is a gap because of the missing bolt. The only way to extract it is with an easy out.

Okay, thanks! :)
I'll let it idle a while and then get that missing bolt fixed.

OH SHIT, NOOO!!!!!
I let it run for 25 min and went out and sat in it. It started getting hot. The temp gauge went up and I could hear the sizzling when I shut it off.

All that white smoke makes me think headgasket. Or a shitload of carb cleaner being combusted. How hot did it get and where'd you hear sizzling from? Coulda blown out your intake manifold gasket too

Nothing other than the sizzling and white smoke.
No gaskets or anything, but I sure phucked this up.

Gonna have to give me some more info to work with.

Lbwd contacted me via PM's. Probably should have kept it here so everyone is on top of the situation. He sprayed TB cleaner into the manifold. It is probably pooled and that is what the sizzling is. I told him to idle the engine to heat it and burn off the liquid, but there must be a lot in there. I then said to hold the throttle plate open and stuff a rag in there to soak up as much as possible or get a shop vac and tape a small hose to the nozzle and shove it in there to suck out as much as possible, then run the engine again to heat it up and evaporate as much as possible before driving it so as not so suck in a slug and hydrolock it. I also suggested blocking the throttle plate open while it sat overnight to give the cleaner some ventilation for evaporation. I think he just got carried away with the cleaner and will be OK once it evaporates and burns off.

Thanks, Ranger.
Indeed I got carried away w. the cleaner :)
I have the shop vac and the custom tube and I am going to clean it in a few minutes. Will report back later, maybe tomorrow so it has plenty of time to dry out.

Good luck. I have to get ready for work. I'll check back in latter.

I used the shop vac and I didn't get much out...
I used a sheet and stuffed it in. How far back should I go?
Is there a way I can remove the top end and get directly to it?

Another update:
I left the hose to the shop-vac in there, with the shop-vac turned on and I let it set like that for a fair while. As of now, the TB is propped open with a pipe.

As I look into the area behind the TB, I can see only a little moisture; no puddles from what I can see. I also got new screws to hold the MAF screen on. I'll re-assemble it later and idle it.

The TB junk is on the shirt and old walmart tooth brushes. The rest of the photos are carbon build up and the inside, behind the TB...

:eek: Holy carbon Batman! That thing was in dire need of a cleaning. One more thing to try. On the front of the engine, behind the P/S pump there is a big "hole" on the front of the manifold. There is a spring loaded door (pressure relief valve). If you can pull it open (outward) you may get access to the opposite end of the manifold to vacuum and stuff a rag. Be careful not to damage any seals around the perimeter or you'll have a vacuum leak and another problem. Then go back and start it again. Let it run and get hot. If you hear sizzling, let it go, thats just liquid boiling and that is what you want. Vaporize it and burn it. Once it starts running better, throttle it up a little. If all seems well take her for a ride.

I can't find the hole. Does the engine cover need to be removed?

I don't think so. It is exactly opposite of the TB. If you can't find it or get at it, forget it. Just start it and run it some more like I said in the last post and see how it reacts.

So far the start and idle are good.
The rev (revved once) still has some gargling.
I'll let it idle longer.

So far there's no over heating...
I have my hopes up :)

It'll be fine. Once you can drive it and are comfortable that there is no pooling in the manifold (I doubt it anymore), give her some WOT.

It heats up a bit, then cools back down. I'll give it a little more time, then take a ride tonight :)

One other question, if you have the answer...
My temp guage is always just slightly over the mid point, just slightly.
Is there something I should do?

Thanks for all of your help, too :thumbsup:

Sounds about normal. Nothing I'd get too excited about. Thermostat ever been replaced? Condenser clear of bugs? Purge line clear? Belt tensioner tight?

Okay, thanks.
Still can't drive her yet... hear the gargle upon rev. It's not getting hot anymore, but th rpm moves around a notch under 1000.

Still workin on that part.
Can't wait to drive it... should I drive if it gargles like that?

Hold the throttle at the gargle point and see if it goes away. Are you sure the "gargle" is not a misfire?

A misfire from what though? Will test again...

It gargles when I release the accelerator.

Misfire maybe from a fouled plug from too much TB cleaner. Does the exhaust smell normal or like TB cleaner? The gargling is from the exhaust?

The gargling is from the exhaust, yes.
The exhaust, on 2000+ RPM is whitish in color.
It smells off, not like exhaust, more like the cleaner I used.
It's also still heating a bit much.

It actually smells fairly normal, like really rich premium fuel.

Is there something I need to blow out via the accelerator?
I still can't drive it until I can tell what's going on :(

How much of that stuff did you spray in the manifold?

I don't know -- but it was a lot I guess. I mostly sprayed it upward into there, some straight back.

It ought to be gone by now.

I have had RF2560 for a while now, maybe about 3 months...
Should I drive it even if there is that gargle?

it heats up upon acceleration now

How hot?

It goes almost one notch past the mid point.

I'd take it for a ride.

Okay, I'll try in a sec. I'll drive slow to start with. Just hop it doesn't do the hydroplane thing.

He he, I think you mean hydrolock. I don't think you sprayed enough in there to hydrolock it. Besides, it's been running long enough and is hot enough to have evaporated it by now.

OK COOL! LOL I didn't know I said 'hydroplane' LMAO! Nice :cool:
I promise that I meant to say hydrolock, I just wasn't paying attn.

Sweet...
Drives normal. Now I'm taking it out of the hood and onto the roads...

Keep us posted.

Alright! She drives and rides good. I am letting the exhaust tips cool down before I cover her up for the night. I think I'll do some WOT tomorrow. I did get into the high RPM's. She stays normal temperature-wise as well :)

Thanks Ranger and all :thumbsup:
I appreciate your kind help and effort!

Whew, glad that's over with.

Maybe Im stupid, but how did this have anything to do with the coolant temperature?

BTSOM (shrug)

Maybe Im stupid, but how did this have anything to do with the coolant temperature?

What, the TB? Everything.
I still have some exhaust gargle, but I am not sure that third screw is holding the MAF screen tight enough. I'm going to get the $4.00 screw from the dealer next week.
