Camry :: 2002 XLE - High Idle After Cleaning Throttle Body
2002 Camry XLE.
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).
Grand Prix :: 2002 Pontiac Speed Dropping On Highway - Temperature Really High On Gauge
One day, I was on the highway and my Pontiac's speed started dropping. I looked at the temperature gauge, and the temperature was really high. I flushed the coolant system, and changed the gasket. Also the mechanic said that the oil might be leaking after they changed the oil. I paid like $700 for something that has nothing to do with the problem (I paid for a spark plug, ignition wires, fuel filter, and an oxygen sensor). After they changed the oil, oil started leaking all over my driveway, which didn't happen before. It also looked like coolant was leaking out. None of this happened before I got my oil changed with these guys.
After I changed the gasket, the car was running smoothly. But today, the same thing happened again, and I don't know if it's the thermostat, or water pump, or oil leaking, or coolant. The mechanic always suggests to fix something that doesn't have to do with the problem. I don't have much money on hand, so I need to only fix what has to do with the temperature rising, and I need my car to run.
Grand Prix :: 2001 Pontiac GT - High Idle / Stuck Accelerator After Fuel Filter Change
I just changed my fuel filter and now I am having issues with the idle/accelator. When I get the car going to a speed of 40mph for example, I let off the gas and the speed barely drops. Then when I went down a side street about 20 mph, I let off the gas and the car just kept going. The idle was initally high, but then dropped down to it's normal 800rpm.
The only thing I touched under the hood was releasing the pressure from the fuel pressure regulator before the fuel filter change. I just removed the idle control unit and cleaned it but that didn't work.

View 1 RepliesGrand Prix :: 1997 GT Running Extremely Rich And Pressure Build Up In Fuel Tank
I'm having this weird problem with my car, 90% of the time it will start to run rich, until it reaches normal temp, to the point that I can smell it coming out from the exhaust. LTFT is at around -15% and it seems to go down after cruising for some time but will go back to negative at idle. My first suspect was the FPR so I checked it and found no gas smell on the vacuum hose, then I decided to run the engine with the vacuum hose disconnected and see if any fuel would come out, 5 minutes later and it was still dry.
There is a chance that the MAF sensor is bad, I'm 90% sure it is, because it will sometimes read 2.9-3.1 gps at idle and according to the rule of thumb of 1gps per liter of displacement, it shouldn't go that low but I might be wrong about it; I disconnected the MAF and the smell was still there, today while driving it was reading 5.45gps (A/C was on) and the smell was still present; car also feels sluggish from time to time only at normal operating temperature (which I assume is because of it running rich).
There is also a vibration felt through the steering wheel only while idling in gear at all temps. Today when I got home and after I turned off the engine I heard a noise like water was running. It was coming from the car so I tried to find where the noise was coming from and it's from the fuel tank. I removed the fuel cap and lots of air came out (or sucked in?). I reinstalled the cap and pressure started to build up almost immediately! I have a video, which I'm sharing, so you can see what I'm talking about; I was even able to hear the fuel tank expanding because of the pressure inside, not sure if you can hear it towards the end of the video (when I put the phone under the car). [URL] .....
It also happened today that I was cruising and the engine hit the rev limiter after I stepped on the gas (WOT) to overtake another car. I immediately removed the foot from the pedal and gave it less gas and it acted normal, no slipping from the transmission at any other time. There is one more thing that I'm not sure about it. Every morning, the engine will sputter for 1 or 2 seconds after starting it but it will be fine for the rest of the day. I once tried disconnecting different sensors from the engine and the only one that seemed to make a difference (it didn't sputter) was the TPS.
Things done so far:
- I replaced the EVAP purge solenoid (P0441 was present) back in february.
- Rubber pieces at charcoal canister also replaced, old ones were rotted to the point my hands would look black just by rubbing against the hoses.
- Upper intake manifold was also replaced by me in november last year.
- New NGK spark plugs and OEM spark plug wires last december.
- Cleaned the MAF sensor with MAF cleaner, no dice. Used brake clean, no change. It's a reman Cardone from autozone, which tells us it's 90% sure it's broken.
- New Duralast MAP sensor back in 2010 because a mechanic broke the original.
- 10qts transmission fluid and filter replacement 2 weeks ago.
- Fuel pump was also replaced back in 2009 maybe, can't remember the exact year. The old one would start making some kind of a hissing noise after prolonged driving.
NO DTC'S PRESENT. I once checked Mode $06 data with a mid-level scanner I have (AutoXray EZ-scan 6000) and saw a test had failed, I think it said something about the MAF and EGR. IHaven't connected my fuel pressure gauge tester. Since I can smell it running rich, I didn't think it would be necessary. I'm thinking that there could be a problem with the EVAP system that's causing the excessive pressure in the tank but I'm not sure what that could be. Is there any chance that the pressure is also causing the rich mixture?
Camry :: 2004 V6 LE - High Idle After Throttle Body Cleaning
I 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.

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.
Ford F-150 - 1997-2003 :: 1999 - High Idle After Cleaning Throttle Body
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.

View 3 RepliesHonda - Accord :: 2008 - After Cleaning Throttle Body Getting Code P0507 - High Idle?
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
Grand Prix :: BTSI / Gear Shift Knob Removal?
I've tolerated having to release my key with the manual push button for years. Now the interior is disassembled (after replacing evap core) so I'm looking into fixing the BTSI.
I've never been clear on whether the problem is in the console by the gear shift or in the steering column. The thing is in the steering and has a solenoid that will mechanically allow the key to turn to the LOCK position when energized. The manual release is at the bottom.
I connected the leads of that white thing to battery voltage and sure enough, the post retracts. So that seems to work. However, when connected to the car wiring, there is not enough voltage to retract. It retract, it will hold. I concluded the problem is near the gear shift. Probing the lead (with the white thing disconnected) indicate battery voltage, but that's without any current.
Battery voltage is getting to the wiring harness in the console. Probing the leads to the Park switch indicates 90 ohms resistance. I suspect this is too high and causing a big voltage drop so there's not enough to energize the solenoid in the column.
What can be replaced in the console to remedy this? Is it only the park switch?
How is the gear shift knob removed? I see a slit in the back of the knob, but don't know how the mechanism works.

Grand Prix :: 2003 3.1L SE - Idles High Around 3000rpm In Park Or Neutral After Thermostat Replaced
I replaced the thermostat in my 2000 3.1L Grand Prix SE yesterday. I had to remove the throttle body to get access to it. After putting it all back together, my car now idles around 3000rpm in Park or Neutral. It drops to around 2k when driving which is still a little high. I can definitely feel it taking off faster and it seems to buck a little bit here and there while driving. I did hear a loud hissing sound when I first started it up right around the throttle body area. I don't hear the hissing sound anymore, though. It justs sounds like it's running a lot harder. So my question is, would a leak around the throttle body (I did not use a new gasket and it's possible that the gasket wasn't properly seated) cause these symptoms? On the plus side, my car seemed to heat up super fast!

Drove 28mi out to dinner and when leaving after, she wouldn't start. Took it to work in the morning, and it ran fine prior to that. It was 15degrees outside, added heat to the gastank thinking the fuel line was frozen. Tryed to fire on, but it would only idle briefly surging while doing so and die, like not enough gas. It did start after I held the key down during this surging process grinding the starter also, should have driven home, but I shut it off like a idiot, as a result, had to tow home. Noticed TCS OFF light was lite up while it was running, then I shut it off, TCS OFF LIGHT went away when I turned key back on to attempt a 2nd restart. After i did that, it wouldn't fire on again. Towed to my house, I do not hear the fuel pump trying to kick on when i turn on the key. Fuel system is dry. Cranked over next day and definitely no gas in the lines. Bled the fuel system, no fuel shot out. Have checked the fuse box and the one under the hood too. Replaced the fuel pump relay but still no go just (this blows)...
