Camry :: 2008 Engine Don't Idle / In Reverse, RPM Drops
I own Camry 2008, 4 cyl, 2AZFE engine, 2400cc.
I recently, started facing strange issues,
No matter whether engine is stone cold or oven hot, it does not idle where it used to be (2 weeks ago). The car idles at ~800 RPM and the rpm suddenly drops to ~700 and engine flushes in more fuel to rev it up to 1100 rpm. Will take another 10 - 12 sec to reach ~700 rpm and the same story continues.
This however, sometimes go away, in Neutral. Once I put it in Reverse the problem becomes worse with RPM dropping every other second, as if the current in the coils is failing.
All this fuss continues, even when car is at 30 mph. However beyond 30 mph I feel nothing.
Services done in last 2 weeks:
1. Throttle body clean-- complete removal of all the gunk.
2. PCV valve changed from toyota dealer.
3. Mass airflow sensor cleaned.
4. Spark Plugs changed with new Iridium plugs from toyota dealer.
5. New Ignition Coils.
Nothing solved the idle problem - missing in the car. The mechanic convinced me that Head gasket is blown. He was indeed right as the Head Gasket had crack b/w cyl 2 and cyl 3. It was changed and car was much better. But now I am again facing issues.
Yaris/Scion & Vitz :: 2007 - Shaking / Rattling During Idle - Running Roughly
I have a Toyota Yaris '07 ... The car has been running pretty rough and ready over the last few weeks... During idle, it started rattling & shaking pretty hard... this progressed with the add-on feature of changing revs during an otherwise steady drive..... It chose the (in)opportune time of driving with our 3-year-old son, grumpy at that time, down heavily trafficked busy roadways during the holidays and stalled 3 x times.... It is in the garage/service center for the 2nd time ... They are stumped. They've checked air, fuel mix, filters, injectors, spark plugs, etc., basics. Computer diagnostics show nothing (briefly showed fault at Cylinder #4 but then that changed and now showing nothing). Toyota Technical is (apparently) stumped. They are talking about needing to order a new computer from Japan (minimum $1200 just for the part).

I have a 1996 Dodge Ram 1500 5.9L V8 4x4 ... Automatic transmission sport model
I have a severe shaking at 1500 rpm last gear and a slight shaking at idle doesn't shake when I'm off the gas barely shake when I kick it into higher revs but I than hear piston slap.
I replaced the spark plugs and I have brand new U-joints. Last night I checked all the plug wires and they are all getting spark. But my exhaust is skipping like I'm not firing in a couple cylinders
I checked the rear transmission mount (I'm replacing it). And the Engine mounts look ok but I'll check again today
I've read a ton of forums and they all have different answers so I'm really trying to figure out what is wrong before I spend a bunch of money replacing things that won't fix it!
I've read that it can be my tranny, TC, Harmonic Balancer, Steering Stabilizer, pinions, Tie rods, Steering(over all), IAC, Fuel System, IgnitionSystem.

View 6 RepliesTiguan :: 2013 - RPM Drops Quickly When Idle
I purchased a CPO 2013 Tiguan about 5 weeks ago with just under 29k miles. I now have about 30.5k miles. I have noticed this occur a couple of times. After the car is warmed up, and I am sitting idle for a little bit, I notice the RPMS bounce down to about 600, but then quickly correct itself and get back up to 750-800. When I purchased the car, they said they did the 30k mile maintenance. I have done 1 oil change withe the Pennzoil Platinum 5w40 euro blend. I do not feel like the oil change is the issue at all as I have changed oil plenty of times with numerous cars. Maybe I just need the ECU re-flashed?

On my 2001 Prius, while driving down the road the red triangle comes on and the ICE drops down to idle and the car slows down to 29mph. If I floor the gas peddle the car may or may not pick up speed slowly but if I let off of the gas peddle the least little bit it will slow down to 29mph. If I stop and turn the car off and then back on the triangle is still there but the car runs fine. After turning the car on and off 2 or 3 times the triangle disappears.
View 2 RepliesGolf/GTI VII :: Rough Idle And Shuts Down Sometimes
Symptoms:
- rough start-up, car shuts down
- backfire when releasing after WOT
- OBD-II codes (see below)
Okay so these issues started to appear only 1 day after I got tuned...
Problem History:
Day 1:
- car started mildly rough
- I got an EPC light on my dash 2 minutes after moving and for 2 seconds the car sounded like an STI (the sound you hear with a misfire)
- I turned it off and on, EPC gone car started up normally
- took it straight to dealer, they checked coils and plugs and said that it's a tune issue.
- went to take it back from the dealer and that was the first time the car shutdown immediately after start-up. it started at second attempt with a quite long ignition sound and the STI-like sound briefly once again.
Day 2:
- I went to my friend and we pulled the codes from OBD-II and only got the P0420 00 [175] - Efficiency Below Threshold code only (as the dealer probably erased any other code related to my EPC light)
- we deleted the code and drove around
- every time we turn the car off and on. The car starts up mildly rough and the code comes back up
Every 2 days or so:
- the car would require 2 attempts to start but no EPC light coming up.
Day 4:
- I had a night of possibly 6 WOTs to test the cars performance, and it was performing great. didn't feel any loss in power or anything. (was friendly racing my friends modded 135i with very impressive outcomes)
- car backfires after i release the gas pedal at WOT (not with every WOT but 2 out of 6 runs it backfired)
- After the last WOT i got the EPC light. turned the car off and let her relax for 5 minutes.
- car took 2 attempts to startup. with severe roughness and shakes (as if the car is cammed V8 engine) for 5 seconds and then back to normal.
Now since the EPC light came back on i wanted to check if there is another code from the OBD-II. I was hoping that the issue will only be the P0420 00 [175] - Efficiency Below Threshold code but my fears were true and i got another very annoying code
This is last nights code pull
2 Faults Found:
14914 - Boost Pressure Regulation
P0299 00 [096] - Control Range Not Reached
Intermittent - Not Confirmed - Tested Since Memory Clear
[Code] .....
Day 7:
- The car had the sever start-up roughness again
As I'm trying to find a solution for my problem here are the steps i took/will take:
- took it to the dealer for nothing.
- ordered an O2 sensor extender for the P0420 00 [175] - Efficiency Below Threshold code and i hope it's somewhat related to the start-up issue. it will arrive today or tomorrow.
- once the extender is here, I'll take it to an exhaust shop to install the extender and check for any DP/Exhaust leaks
- I will take it to a mechanic to check any leaks in all intake/air connectors and piping, any leaks in DV (I have forge recirculating DV), Boost pressure sensors (the piggy back was connected to them and one might be loose when we removed it), spark plugs and coils.
Passat (B5) :: GLX Shuts Off When Levels At Idle
I've been searching for a few days, Can not find an exact same posted issue. 2004 Passat GLX 2.8 Auto FWD. The car starts great, will idle all day if you let it. Will move down the driveway or a small ways down the road and die. start it again, will start easy. die once it levels at idle. Also if you rev it, it will die within a second of revving. If you can get it high enough, say 4000+ it will die, but as the engine speed slows down it will catch again and come alive. and kinda repeat. will do that as long as you hold the gas down. after about 15mins of restarting, it will level out at idle and you can continue on your way. the fuel pump still runs for it's second after the engine dies, so i know it's still going. The car recently had new plugs put on, New brake switch, and the pcv hose that runs from passenger side valve cover to the rear of drivers side along the front was replaced with the same size rubber hose. it broke during new plug install. It idles smooth, drives good while acting right. but does have a noticeable power loss, but still very driveable.
View 1 RepliesVolvo :: Idles At About 1200 RPM / When Engage Drive Idle Drops To Very Low
My Auto 2.4 850 SE (38600miles) does this lately:
- idles at about 1200 rpm, and takes long to settle to its 850 position, even when warm;
- when I engage Drive, idle drops to very low, car vibrates as if engine wants to switch off, then rises again as I give gas and pull away.
Why this is the case, and what I could do to remedy this? (About 2 months ago, idling was going really nuts! I removed the flame trap and fresh air hose: it was full of oily gunk and I gave all components a good clean up with carb cleaner and then replaced them, and then idling all fine after that).
Golf IV R32 :: Startup Then Drops To Almost Dead And Goes Back Up To Normal Idle
So every morning I get in my car and start it up. Usually, It starts right up, hit 1.5K RPM and then drops to almost dead (~3-400RPM) and then goes back up to a normal idle. This has always concerned me but never thought too much of it since the car goes right back to normal after a few seconds. Today the car did the normal startup and then died. What is causing this?

View 3 RepliesCivic - Honda :: 2004 - Temperature Gauge Drops At Idle
I have a 2004 Honda Civic that has about 183,000 miles.The problem is that when I start my car in the morning, the car never totally warms up when it's cold outside (I live in VA), until I press the gas pedal and rev the engine. Until I press the gas pedal, the temperature gauge stays at cold, and the heater blows cool air. I've taken it to the dealer 12 times for the same issue, but they can never find the real problem.
They flushed the A/C hoses and radiator, replaced the radiator cap, installed an upper hose, installed head gasket, water pump, and while there, the timing belt. They've also "burped" it numerous times. Also, when I have the heater on and fan on high, the temperature gauge drops as I'm going down a mountain and not pressing the gas pedal. After driving, and I stop, it also slowly drops while idling for about 5 - 10 min.
When it's warmer outside, I don't have any problems, because I don't have the heater on. This has been going on for about 1 1/2 years now, and it's starting to get cooler again, so I need to get it fixed or sell it.

Sierra :: 02 Dies As Idle Drops When Slow Down To Park Or At A Stop Sign
I got a 2002 sierra 1500 with a 5.3l. I just replaced both catalytic converters and y pipe. After I did this, I am having a few problems. First, when slow down to park or at a stop sign the idle drops way down and it dies. I cleaned the throttle body, maf sensor, and ran a can of seafoam and a can of b12 chemtool through it. It did this for a couple of days and now when the idle slows down the "check oil pressure" light comes on before it dies. Then yesterday the "check oil level" light started coming on. Is this all related, would the low idle cause low oil pressure, where to start?
View 1 RepliesDodge - Stratus :: 2003 2.7L - Stalling At Idle / Engine Suddenly Drops RPM When Hot
I have a 2.7L flex fuel Dodge Stratus with 120K+ miles on it and a problem local mechanics and the Dodge dealership cannot seem to locate. When the engine is hot, and only when it's hot, the car will jerk suddenly while driving for a split second, then resume normal operations. It feels almost like you hit something and is scaring the bejeesus out of my wife. It also sometimes stalls out when at a light after sitting at idle for a few seconds. It idles down from 600 RPM like the air conditioning compressor is cutting on and then dies completely.
The car shows no error codes and the check engine light does not come on when this happens. I have replaced the spark plugs, and the transmission solenoid, which is what the Dodge dealer said "fixed" the car for almost $900, and it did it again on the way home from the dealership. My next idea was to change the fuel filter, or maybe the cam position sensor or timing belt or chain. I wonder if I am just trowing money down a hole at this point though, since Kelly Blue Book on this car is under 2K anyway.
Santa Fe (CM - 2007-12) :: Idle Drops And Loss Power After Engine Warms Up
When I start the engine it works fine while the motor is cold (idle normal all smooth). When the engine the temperature reach normal operating range the car loose power and idle drops to 350-500 rpm and if i am driving I can not go over 40mi/h. I drive a 2008 Sta Fe now with 96000 KM (~~60000 miles). A month ago the engine start shaking severely and knocking noise (like some spark plugs where not working), from this to now:
Changed all sparks plugs
Changed all ignition coils
Now this situation looks more related to temperature of the engine.

My wife has her 03 escape v6. It has a very rough and low idle. On start up it idles nicely and then the idle drops and pulses if that makes any sense. I've pulled I think its the idle control sensor. It killed the engine as soon as I did. I've cleaned the throttle body.
