Acura - TL :: 2003 - Hesitation On Cold Start

When I start my car from a cold start - mostly in the AM, the car hesitates to start - but always starts. But the check engine light comes on along with the Vehicle Stability Assist indicator light and the VSA Activation Indicator lights come on. If I let the car warm up and then shut it off and restart, all lights go off except the check engine light. After two or three stops and starts (shut off and restart) the check engine light goes off.

I took it too the dealer and they said the computer indicated the cooling system had a malfunction. They did a pressure test on the system which indicated a leak. However, they could not find any coolant leaking from the radiator or belts. They only conclusion they could come to is that the head gasket "might" be cracked. The oil has not indication that the coolant is leaking into the oil.

There is no smoke coming from the tail pipes. So they said they think the exhaust is leaking into the radiator and forcing the coolant into the coolant reservoir thus leading to the engine to "overheat". BUT the engine is not overheating. if it is a cracked head gasket, will additives to the radiator such as Steelseal or blue devil really work?

Silverado :: 99 With 4.8 - Rough Idle And Hesitation On Cold Start Up

I have a 99 silverado with the 4.8 w/186k on the clock. I am having an issue with rough idle and hesitation on cold start up. Once the truck warms up the idle and hesitation go away. I have replaced the PCV valve hoping this fixed it, but it did not. I have also cleaned the TB and the MAF.

GTI 337/20th Anniversary :: 1.8T Cold Start Hesitation - Choking And Sputtering

Recently purchased a 2005 Jetta GLI with 31,xxx miles on it. It is my second 1.8T. My first was very reliable, with never any issues even after the 100k mile mark and is the reason I didn't hesitate to buy another one. That, and the Recaro Edition GLI has always been one of my favorite cars.

So I've had it for about a month now and I've noticed on occasion a problem with cold starting. One weekend it sat for almost two days because we used our other car, and then again this morning it was particularly chilly here in Pittsburgh, about 35degrees F and it took me two starts to get it going.

I always turn the key to 'on' for a few seconds and let the fuel pressurize and all the indicators light up. It doesn't appear to be the battery as it turns over strong, though I have not yet confirmed this is a Voltage reading. Once it kicks over, it seems to be choking or sputtering, unable to get up to idle. The second time, it does it again but gets past it and all is well...

I'm checking records now to see if the 30k mile service was completed. perhaps a tune up and new plugs would work?

Sonata NF (2006-10) :: 2007 3.3L - Cold Start Hesitation / ESC-Off And CEL Illuminates

Relative owns a 2007 Sonata 3.3L V6 (58k or so), purchased from in-laws so no warranty, unfortunately. Recently, in cold weather the car has developed hesitation issues upon start up, ESC-Off light illuminates and CEL. Has to restart for somewhat normal operation.

Had a chance to look at it today and CEL had already turned off and only code stored is P2135.

Researching issue (mostly here, so thx!), looks like TPS is faulty and can be replaced separate from throttle body to save $.

Sonata NF (2006-10) :: Hesitation When Engine Is Cold

Ok, got a hesitation when the engine is cold, almost feels like a miss. Dealer could not find anything and there are no engine codes. They wanted to replace the plugs with new platinum plugs. I said did you pull any plugs, not that is what the tech said it could be. Could it be the Mass air flow sensor? Or a coil. After a mile or 2 it is fine. I switched to shell premium since dealer told me I had to get a decarbonization from using cheap gas. I used exxon regular and BP regular with a treat of premium every few tanks. But now I am on shell and they said I needed another decarbonization, This is getting rather expensive, I may go back to my local mechanic once the warranty is out. But the hesitation puzzles me.

Ford F-150 (2009-2014) :: Slight Stumble / Hesitation When Start The Truck Cold

A couple questions I have about my truck. I'm still new to the F150.

First, my truck has an Ecoboost and I have a slight stumble/hesitation when you start the truck cold. It clears up within 10 seconds and doesn't seem to affect drivability whatsoever.

Second, it seems that only my driver side mirror has the "dimming feature" to it. Is this normal?

Ford 6.0L Power Stroke Diesel :: 2007 F350 DRW - Cold Start Hesitation No DTC / CEL

Recently I replaced the unison ring on my turbo, EBP sensor and cleaned carbon out EBP tube/upper part of motor. After doing so she seemed to run fine but not like I remember when I first got her. Plenty of power but ever so slightly off, only an owner would notice. Few weeks later she hesitates a little bit while she's cold in the morning. I let her run 3-5 minutes b4 actually driving but as u know it's a little while to get up to operating temp. Temps seem OK 190-200 EOT/ECT. Fresh oil/filter, air filter, coolant, EGR was cleaned out a little while back and EGR valve replaced 25k ago. I'm not sure where to look at this point...the motor has about 30k on it.

Prius (2010-12) :: Low Rev Cold Start With Delaying Engine Shutdown

My Prius is having a problem during cold start. When I bought it, the cold start was very energetic with a high rev tone then gradually regulate to a normal pace and petrol engine shuts down. But about 4 months I noticed the tone of the cold start has changed, it starts with a weak and low engine rev and delays to turn off the engine. Today it took about 10 mins to power off the engine. Got 2 months I changed my 12V battery (Bosch now), thought that these symptoms was to notify that battery is failing. But the problem is persistent despite I put new battery..

Prius (2004-09) :: Engine Speed Higher Than Before Mainly On Cold Start Or Go Uphill

I found recently that my 04' Prius' engine easily goes higher rev than before (based on engine sound pitch). It happens mainly when cold start, go up hill. After warmed up and on flat road, it goes back to normal. Overall, still in great condition at 211K. MPG stays at 46 on meter when temp is around 45F with 50% highway drive at 100 miles/day. I suspect the serpentine belt slippery or something. What do you think? I think the belt is original. I bought it used at 104K.

Prius (2010-12) :: Rough Cold Start - Engine Sounded Like Working On 3 Cylinders

So I had 1st rough cold start today on 2010 Prius with 72K. Wasn't too cold low 40s. The fix was to shut it down and then turn on again.

Engine sounded like it was working on 3 cylinders. It is probably ignition or perhaps valve train issue.. with ignition being prime suspect. If it happens again I'll pull and check plugs.

Ford - Mustang :: 1971 - Cold Engine Start Fine But Will Not Start When Warmed Up / Sluggish Crank

A cold engine crank will turnover and start normally. But stop to run and errand or grab lunch...and the warm 302 2 barrel engine will turn over very sluggishly, lke the battery is dying. If you wait until the engine is cool, an easy start is assured but that takes hours! A local repair shop has rebuilt the carb, the battery & cables are new, and the starter works fine when engine is cold. My local repair shop is out of suggestions. It seems to work a little to hold the gas pedal down on the floor for a warm engine start....but engine still turns over sluggishly when trying to start when warm. Now If I drive it.....I just drive it around town a bit then back home ...unless I stay several hours somewhere while the engine cools....but that's not fun. It is a convertible, fun to drive...and this problem needs to be solved.

Passat (B6) :: FSI Engine Chirp Noise When Start The Car And Engine Is Cold

I have a 2008 FSI engine and I have a chirping noise when I start the car and the engine is cold. The noise goes away when the engine is warmed up. This noise has been like this for a very long time (more than two years) and I was not seriously concerned about this until I found the below video which has exactly the same noise.

The owner in the below video says that the timing belt and the belt tensioner had to be replaced and that his engine was only at 26K miles. I am at 46K miles right now but I definitely had this noise when I was around 20K miles as well.

Honda - Accord :: Hesitation During Acceleration When Cold On V6

I have a 2003 Honda Accord V6 that has some acceleration hesitation and general jerkiness, usually noticeable when the car has been sitting for a long period of time (overnight). The symptoms seem to dissipate after 5 - 10 minutes of driving.

When I begin accelerating, the car feels like it hesitates when shifting from 1st to 2nd gear. If I let off the gas a bit, then the car jerks a bit.

I'm sure it's not the transmission, because the dealer said the fluid and everything looks fine. Additionally, I have another Accord (2000) that does have a failing transmission and the symptoms on that one are very different from this 2003.

A couple of months ago, I was getting a CEL and had a friend of mine read the code with his OBD tool. It indicated that Bank 1 Sensor 1 was bad. I replaced it with a Denso. I think the problem got better at that point, but has "worsened" again over the past month or so.

Any clues what this might be? Things I can try? Ways to narrow down the issue?

Phaeton :: Hesitation When First Pulling Away From A Dead Stop Especially When Cold

I need to better qualify when it happens (it may be always, not certain) but when I first drive off in my car in the morning I find the initial 10s or so there is a delay before my power comes on stream.

So I am moving, but very slowly and the V8 doesn't seem to be pulling. There is a stop sign at the end of my street that is maybe 5 houses away, so there isn't a lot of time for acceleration, but its mostly momentum before I hit the stop sign, even if I had depressed the accelerator.

It doesn't jerk or anything when the power comes online but it is very strange to me that there is a delay. Is this normal or an indication of a problem or wear item somewhere?
