Acura - TL :: 2003 - Hesitation On Cold Start
Oct 2, 2013
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?

My 1991 Acura Legend LS does not start in cold weather and in the morning. Once it does, it keeps on starting and runs great. Prior to catching and starting it rattles and shakes and when I press the accelerator, it makes sounds like it is not getting enough air. The problem occured abruptly after a mechanic tried to find out why the radiator fan does not come on. That has been fixed by putting a new relay. The car has 176,000 miles and has never given starting problem before.

2000 Acura Integra 98k miles. Around 90k timing belt, water pump and all sealants were done - and valve adjustment.
Since then I thought that there is a minor loss of coolant - also heard some grinding sound at cold start.
Today in calif, weather is under freezing. I saw handful of coolant under the car where the water pump is. The reserve tank is almost empty - at 95k coolant was topped up.
I went to another mechanic and he wanted to bring the car next week - he will try pressure test - if it is minor leak, it might not work he said - will do other tests. Didn't say the price. Not sure what the fee is for diagnostic.
What are some practical tips? This is the first car now and plan on keeping it. Given it is been about 2yrs with the timing belt job, I am not sure if I have any recourse. Credit card companies only take care if it is within 2 yrs.

Experiencing engine hesitation after a cold start? I've have noticed this and after the engine is warm there is no hesitation.

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.

My 2003 Acura TL has trouble starting if I am running errands and the car is turned off and then I turn it back on. This only occurs when the air temp is 50 degrees. I have had the local Acura dealer evaluate it without a confirmed diagnosis.

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?

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 $.

My '92 Integra has ~280K miles. A couple of years ago the tachometer started "bouncing" up and down while the engine seemed to run fine. Some time after, it started to hesitate under acceleration. A few months ago the car died while driving along the highway. The tachometer went up and down as the engine cut off and came back on before finally dying. A tow to the repair shop lead to a tune up, changing of spark plugs, wires, distributor cap and the ignition coil. That got the car running again, with its usual erratic tach and hesitation on acceleration. Then, the car died again in a similar way while driving. I was found to have a dead battery. Replacing it got the car running again...but the tach is still erratic and the car still hesitates. I am concerned that there is still some underlying issue that has not been fixed. I sometimes think it is a loose connection because there are times when the car seems just fine, but that is happening less frequently.

The last few days, when I would start my 1990 Acura Integra (morning or afternoon after sitting at work), it had just the slightest hesitation before the engine would start or "turn over", if that is the correct term.
Sometimes I just thought I did not have the clutch engaged the whole way and did not worry. This morning I went to start it and it hesitated again, but now won't start at all..makes the clicking starter sound after a second attempt, but nothing else. NO lights were left on!
The Battery (Duralast Gold 8 year battery) was replaced in Feb 2011, the Distributor in August 2011 and the Distributor in 2007. Could it be the latter?

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?

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.

My truck - early 2000 CC short bed, 300K miles
Background on my problem: I had a short list of long overdue maintenance and updates to do that time and money kept me from tackling. Found a little of both so I replaced the water pump, HPOP lines, re O-ringed the HPOP/IPR, deleted the AIH, replaced all of the brake lines in the engine bay, put new fuel lines to the filter bowl. All of this took me about 2 weeks so the truck sat with the batteries out for that long.
After buttoning it all up, it fired right up, a little slower than normal but figured that was air in the fuel lines, HPOP, etc. The only issue I had was the battery light stayed on. Thinking I had an alternator issue, I checked it and it was getting about 14.25v so figured that was good. I used it regularly for about 3 weeks, the light stayed on, and noticed some surging during warm up and some low rpm hesitation.
Then it stop dead on me driving down the road. Turns out it was all my doing, I had torqued the bolts on the water pump pulley but didn't use Locktite. The bolts backed out, shredded the belt, and ended up yanking the CPS wire harness out of the sensor. So that made total sense.
Fast forward another week, got new wiring pigtail and CPS (never replaced it before now) from a couple of the good FTE vendors. I am not sure about the wiring on the pigtail, my truck has a green, blue and brown/gray wires, the wiring diagram I found online showed green, blue and gray. I wired it connecting the brown/gray where the gray line goes (center contact) and closed everything up.
Another thing to mention is that I have an Edge Juice with Attitude that has been on the truck since '06. I lost that connector in the process and they were absolutely no support in trying to get me running again. Wouldn't or couldn't tell me which wire they connect to so I used the green wire which is the CPS signal wire to the ECM. Once I am running again, going to get rid of the Edge.
So that is where I am now. No start, I've been reading some of the "what to do" posts, the most likely is that I don't see the tach bounce when trying to start. So I want to check the wiring to make sure I have good connections to the CPS.
So I don't have any diagnostic software to read codes, etc. I really need to fix this myself and only have one set of hands most of the time. Not really sure what the problem was before it stopped running and now I can't diagnose the surging and hesitating.

96 Acura with a weird habit. On cold mornings, after a few minutes it starts this thing where it revs up about 500 or so, then back down. It does this while parked or when driving. When driving, it still revs up, but also revs down - like it's putting in extra resistance or something; have to give it extra gas when it does that. This usually stops once it warms up. Also, it runs a fair bit higher until warmup, then settles back down to 'normal.'

I have a 2009 Acura TSX that I bought used ~85,000 miles on it. It has been inspected 5 times and each mechanic says the car is basically new in perfect condition. However, it has an extremely difficult time starting after sitting in cold temperatures for more than about 12 hours. If I drive it every 8 hours or so it is fine. Everything has been checked repeatedly; alternator, wiring, battery connection etc. .. . The battery is only 3 months old.

I have an 88 acura integra and the problim is that once in a while it would not start after it had been running. If I let it sit for 5 min it would start. Now it is happening everyday. One time it will start great and run fine, but when I turn it off I don't know if it will start again. I checked the gas and it is getting gas and the pressure is fine, but when it last happened it would turn over but wouldn't start for the rest of the day, I checked and it had no spark. After I replaced the ignition control mod and rotor, it started on the second try but when i got to work and turned it off the same thing. I let it sit for a while (about 15 min) and it started. Like I said after it starts it runs great, lots of power, no missing or any thing.

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.

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?

Once a week or so my car doesn't start right away after I have driven some where, such as to get coffee, the library, or shirts from the cleaners, It makes noise as if it will start, but then gives up. If I sit and wait patiently -- doing nothing for 15 to 20 minutes or so, it will start. The mechanics have checked it over several times, but can't figure out what's wrong. They suggested putting in a new engine relay a week and half ago. Since then, the problem has happened twice.
