2002 mercury grand marquis high vibrating air pressure is in the throttle body it become louder with the more gas you give the car.The vibration is the worst in the idle speed control.The vibration extend all the way down to the air filter.The air filter is not stopped up.The noise use to come and go and the car would cut off at a idle.

I cleaned my throttle body today. Since the throttle plate moves by a motor, in order to keep it open, I turned the key to ON and held the gas pedal down by using some weight.
After I put everything back, the idle was high 2000+, then stays at 1300 to 1400 range. I drove about 10 miles and it is still the same. When stopped at a light in drive, the idle is still 1000
Did I mess up the e-throttle or the throttle position sensor? (Since I used a weight to hold the gas pedal down, I am worried now).
Just took off the throttle body of my 2002 GT to clean it. Had all of the sensors off (IAC, MAF, TPS). Put everything back together and it fired right up but immediately went to 3000 rpm and acted like it would keep climbing.
Thought I was very careful putting everything back together. Obviously the throttle is open but there is no play in the throttle cables. Could it be a sensor?
The rpm with the A/C on are 550 , I was told to replace Throttle body, I did, rpm continue the same,when im driving and I stop the car start vibrating, some one told me that i have to program the new throttle body , how can i do that?
View 3 RepliesI have a 2004 V6 LE with about 135k miles. I cleaned the throttle body two weeks ago, just because I hadn't ever done it. It wasn't too dirty. Before the cleaning, it idled at < 1k revs. Now, when I start the engine cold, it revs at around 1500, sometimes higher. It goes back to normal after the engine warms up to operating temperature.
Also, I hear a very slight high-pitched whining (maybe hissing?) noise when I accelerate. The noise is more prominent when the engine is cold. I checked for vacuum leaks but couldn't find any.
It feels like I'm depressing the gas pedal a little bit when I have it in drive or reverse, and it wants to pull harder than usual. When I bring the car to a stop with light brake pressure, as it drops into first gear, the car gives a slight tug forward, again, as if the gas pedal is depressed. I mention this to show that it's not just an issue with the rpm at startup.
I suspect that the issue lies with the throttle position sensor, which I may have jostled when I moved the throttle valve. The method I used when cleaning was, I first tried opening the valve by hand with the ignition off, but the resistance was much higher than I had anticipated. So I did the key-in method by turning the ignition to ON and putting a brick on the gas pedal. There was a high-pitched whine coming from somewhere in the engine bay when the key was ON, which I had not noticed before; I wonder if that is normal.
This seems to be a rather common issue after cleaning the throttle body cleaning, but there doesn't seem to be any consensus solution besides to wait it out.
I cleaned my daughters throttle body on her 2005 prius. Sprayed it down on the vehicle trying to fix my P0505 code and now its idling high. Is there a learn procedure to reset this after service.
View 6 Replies97 Sierra K1500, 5.7 liter. High pitched whistling sound underhood in the vicinity of the throttle body. Starts after truck warms up and quiets down when accelerating. I've wiggled hoses, disconnected what I could without stalling engine, checked air lines into throttle body, checked air filter, etc. Sound does not change when I apply brakes so I don't think it's related to master cylinder. The only time it changes is when I accelerate, then only gets quiet until I come back to steady speed.
Truck has 85,000, runs great. No codes.
The other day I disconnected battery, then removed and cleaned the throttle body. Now cold-start idle is high, and erratic,
goes to 1,600, drops to 1,000
- back to 1600, drops, up to 1,400
-- wavers there, and then finally,
starts to taper down to steady idle of about 650-700 rpm.
Since battery disconnected, does not seem there would be a chance for TB to "un-synch" with cars computer.
High mileage 1999 4.6 4wd 5 spd: Needed to replace the rear ABS sensor and decided to clean the throttle body too while the battery was unplugged. Cleaned it around the butterfly and not much else. Truck idled at 750 BEFORE cleaning the TB. Now it fluctuates between 820 and 950 rpms. Also tends to stay at a higher rpm after pushing in the clutch and taking it out of gear.
Did a thorough check for vacuum leaks, nothing. After research, I cleaned the IAC and re installed (battery was disconnected then too). No improvement. Unplugged the IAC while running- ZERO change in idle. Installed new IAC, no change whatsoever. Unplugged NEW IAC, no change whatsoever. Is there an issue with the PCM needing time to fully re learn? Am I missing something.
08 Accord. After replacing the starter and cleaning the throttle body I keep having a CEL and the P0507 code.
Checked for leaks around intake, vacuum lines, etc. found none.
Tried the relearn procedure and still no luck. Car idea higher than normal ( just over 1000 rpms warm). Also feels like it wants to pull even when stopped.
So I figure I have either:-damaged the throttle body somehow cleaning it- Have incorrectly implemented the re learn procedure- missed a vacuum leak ( possible but doubtful)- or something else I don't know about
I recently cleaned the throttle body and now it surges up and down. Not really sure what to check next. 2002 toyota camry 4 cyl.
View 3 RepliesI have a 02 1.8t passat that if I don't start it for two days the battery will be totally dead. I have taken it to two places and they cant find what the draw is. The only thing that i could think of is my horn that sometimes when I am in the car it goes of randomly and my right side mirror that sometimes runs on. And my other problem is that when I drive it and I get to 3500rpm the throttle body shots of and I loose all my boost. I got a new turbo installed trying to fix the problem but still keeps happening. The only thing I could think of is that i have a stage 1 revo flash and when I took the old turbo out it may have erased the memory of the flash.
View 2 RepliesSo I'm at my wits end trying to locate (and fix) a loud, high frequency rattle noise inside the engine compartment.
It can be heard when applying the gas pedal a certain amount. In other words, I can "find" the noise and maintain it at a certain rpm.
The noise is coming from the back of the engine near the firewall. It feels and sounds like it's coming from the throttle body plate and vibrating the gas pedal. I cleaned the plate and it isn't loose.
The issue doesn't seem to be affecting engine performance.
The sound is noticeable while driving (under load). When in park, I can find an rpm where the throttle body seems to take a heavy wave of vibration from the engine and hum (but not nearly as loud as while driving). Issue existed before I put on new motor mounts, and still persists after replacing all 4 (although the vibration and noise are reduced).
Took my car in to get the tire and headlight replaced. Not my usual mechanic. While they were in there, they took it upon themselves to open up the filter and root around the throttle body. They said it was heavily gunked up, and asked to clean it. The car has been having serious starting issues, so this made sense to me, so I overlooked them examining a part of the car that had nothing to do with what I'd asked them to repair, and told them to go ahead.
Mechanic cleaned out the throttle body. Now he says there are scratches in it, he suspects from a mouse or rodent. Says it needs to be replaced, but he couldn't source a part today. Either way, I can't afford that. Says it's fine to drive, though.
Whatever they did, the car is now worse. Engine revs up high in park or when I start the car, and then drops dow and keeps revving rhythmically while idle. And I swear that while in drive, it's running faster even with my foot off the gas, and not dropping out of higher gears as fast. I go back and confront the mechanic. He says yes, that's all because of those scratches. But I don't understand how before, when it still had these scratches, WASN'T clean, when it was, in his words, all gunked up, it was working BETTER than it is now, when it's clean and just has those scratches?
2002 camry. The car will not accelerate. The throttle body makes a clicking sound when pedal is depressed.
So.. I took it apart and cleaned the contacts in it. In the mean time located a spare throttle body from a 2003 from a local yard. The old throttle body has a part number 22030-28030 and the replacement has a part number 22030 0H010. The replacement throttle body wouldn't even move when the pedal was depressed.
I put the old one back on.. and now it doesn't click anymore but the car in Park only revs to 2000 rpm's. Its not sticking or having any mechanical issue.
I checked the parts site for Toyota and the replacement is the new number. Superseded. Does the throttle body after replacement need to be reprogrammed? Or whats the deal. I wish I was more Toyota literate when it comes to this.
I have got a 5 door 2002 Golf 1.6l petrol, manual transmission with 190k kilometers on the clock. It has been playing up recently and the authorized VW garage is clueless, but still happy to charge for a miserable job...
The "symptoms" are always the same: I can start the car no problem. Plenty of water coming out of the exhaust and EPC light comes on, no power transmission (or very little). In this state, the engine runs irregular. Before all this happens, you can tell there will be a problem (this is not super obvious), as the car does not run smoothly in neutral, especially when it is at a a hill You might get away with another 50k but that's it.
Breakdown 1: Called out road side assistance and got it towed. Volkswagen dealer retrieved the error code P1564 and they replaced the throttle and some of the contacts of the throttle. (Costs 800 GBP)
Breakdown 2: However, 300 km later, same problem as before road side assistance retrieved error code P0638. The memory was reset and it did run perfectly fine for a short while (2000 km).
Breakdown 3: As before, error message P1564 was read. This time they thought there was a problem with the coil in cylinder 2 and replaced it (250 GBP) - also the one in cylinder 1 as "old". Picked up the car and it was not running smoothly in neutral and it eventually broke down after only 90 km.
What to get changed next? What is the real root of the problem here?
I'm trying to remove the throttle body on my 2002 Echo. However, the transmission dipstick tube is in the way of one of the throttle body bolts. How can I remove the transmission dipstick tube so that I can remove the throttle body?

View 4 Replies2 002 Jetta Bad misfire P0301 a bit long. 02 jetta gls with 2.0 AVH engine auto trans. over summer my brother overheated it & blew head gasket & valves. All parts listed are new between aug and now. I repaired engine as follows new head & bolts head gasket timing belt water pump coolant flange on drivers side new fuel rail and injectors car also has new coil pack, new VW plug wires and 1 week ago new iridium plugs my brother didn?t want car, so i bought it from him. Ran great after I rebuilt top end.
Car did 140 on the turnpike & ran great. once or twice while giving moderate to high throttle CEL would flash and I pulled P0300 as a pending code. Problem stopped after 2 days. last week after 4 hrs of idling(don't ask) started misfiring and CEL flashes constantly P0301 The misfire seems worse at idle and low speed. Car will get to highway speed but has bad pickup. This is what I?ve done/checked New iridium plugs Plug wires 4.5 ohms Coil pack is good and producing enough spark at each wire MAF sensor cleaned Cyl 1 compression good all injectors are clicking and when disconnected cause appropriate CEL error code Brought car to VW dealer for diagnosis VAG COM shows multiple misfire on cyl 1 Mechanic confirmed all the steps I took and components tested ok. He tried new coil pack, new plug and wire for cyl 1 and no change.
My Pontiac also has oil on the engine now with the oil pressure at 120. It started at 40 then went to 60. I had the oil changed and they put 5w30 which they were not supposed to do. I wanted 10w30.
Is this a common problem with Pontiacs? Is there a non engine replacing solution? Will I have to tow it to the mechanic?
So while driving yesterday I had a EPC and Check eng light come on and go away shortly after... maybe 1hr of drive time. Any way I took into dealer today to have them scan and they stated it was an issue with my throttle body.
Now as soon as he told me that he also said he can not do any work under warranty on my engine due to Stage 2 software and intake/down&mid pipe...... no big deal as I figured he would say something like that anyway. Should I take it apart and try to get it cleaned..... or what?
Its a 2010, with roughly 21k miles.... Had APR stage 2 for a few months now and this is the first thing that has come up.
