Sierra :: 1999 V6 - Hard Time Starting When Hot / Engine Idles Very High
Aug 20, 2013
My high mileage V6 1999 Sierra starts fine and runs great in the morning or when it is cold. As soon a you try to restart hot is spins fast enough, but has a very hard time starting. When it does start, there is smoke from the gas and the engine idles very high for about 10 minutes before settling down. Same thing reoccurs over and over when the engine is hot. May idle up to 2500 rpm, cant kick it off.

I have the strangest problem on my 2006 Audi A6: whenever I fill up my tank with gas the car has a very hard time starting. This has happened 3 times in a row now. I run the tank fairly low - to about 1 quarter tank or a little lower but never to empty....then I fill the tank. When I get in the car to start it, the engine just keeps turning over trying to start but will not start. Then I stop trying, let the ignition rest for a bit, and try to start it about 5 minutes later and it starts just fine on the first try.
What could be causing this?One thing that has also started happening around the same time as the problem above is that when I'm idling at a stop light, I notice the car may start to idle roughly and seem like it is about to die out. I am the first and only owner of this car...I take good care of it and am an easy going driver. But I do drive a lot and have about 200,000 miles on it after 7 years.

I have a 1999 F250 Ford with a V-10 gas engine. It has 65000 mi. Mostly, it starts and runs great. However, when its 10-15 degrees F, it has a hard time starting. It may start and run very rough - then smooth out. Or it may not start- I come back in 2-3 min and it will start. Once it starts and gets past the rough/missing stage, its fine. If the temp hits 25 degrees F, it usually starts just fine.
There are no warning lights and I've taken it to 2 different car parts place and plugged in a computer- but it shows no alarm code. I've taken it to 2 mechanics and told them they had to work on it first thing - when its 10 degrees.
Once the temp reaches 25, it'll start every time. Both mechanics found no problem starting - I'm sure they didn't get to the truck until it warmed up. Its hard to fix something that works fine. I don't know where to look, but I don't want a truck I cannot trust to start. I've changed air, fuel filter and spark plugs.

2003 1.8t gti ... Today when I got in my car...it fired up perfectly normal but when I got in it from leaving school it took 5min to fire up. The engine turned over but wouldn't fire all the time as if the spark plugs were bad. So I bought new NGK spark plugs and had the same issue just a little bit ago.
I know the obvious thing would be to change the ignition coils but they're out of stock everywhere so I have to have them shipped. My question is is the ignition coils the problem? They looked a bit worn but nothing serious.

My Focus has 102,000 miles. It has thrown a p0171 code and I have been attempting to fix it. So far this is what I have done:Changed MAF, air filter, PCV Valve, plugs, Valve cover gaskets, Bank 1 O2 sensor and fuel filter. All new. I have cleaned the throttle body, fuel rail intake manifold. Cannot hear vacuum leaks and tested for leaks with carb cleaner.
Symptoms: engine cranks but has a hard time starting, usually on second try. When tank is about half full I get Rough acceleration, higher RPMs (doesn't change gear) and engine stalls on hard left turns. Idle gets rough at times but usually stabilizes at around 700 rpms.
At the beginning, #1 spark plug chamber had a lot of oil in it. It's been a few months and no oil after Valve cover gasket and PCV change. Tested coils and the plugs get a spark. Before I start messing with the fuel pump, am I missing something else that I can do?

We're currently RV camping in the Wyoming Wind River Range at 8500 ft and is getting to freezing at night. The past two mornings the truck has been very difficult to start and I got quite a bit of smoke. This morning it took two or three tries but I got it going.

Have a very high pitched squeal on cold starts as well as when idle occasionally.
Bad compressor?

I now have a 1991 ranger 3.0 super cab. I need a step by step walkthrough of how to time it. Keep in mind that I ha the distributor out while turning the engine over so I need from start to finish, including the spout connector. It runs right now but idles high at the start and the. Stumbles down to about 500rpm and sometimes dies....

I have a 1999 F150 4x4 5.4, I pulled the heads due to blown head gasket. Prior to pulling heads truck started and run fine other than miss on #1 cylinder. I timed the engine according to Haynes manual and posts on this site. Truck is now hard to start and idles very rough. I does seem to smooth out when reving the engine and seems to have plenty of power. Cant find any vacuum leaks or unplugged wires.

I'm having a issue with my Chevy Lumina Z34 (1991). When it's cold outside the car has a hard time starting up! I have to crank it multiple times while giving it gas. When it starts and is warm she runs great. I've been recommended to get a fuel injector flush. I also read synthetic oil could work also. It doesn't happen all the time.

In the morning, my Treg won't start on the first attempt. If I just click the key to the right (to start the automatic ignition process) it just grinds and grinds then dies. The second time it will start. This has only happened the last couple of days. Also I should mention that it has gotten quite cold around here. Although the car is in a garage and my wife's Jetta fires right up.
I've also been having Insufficient Coolant problems. After one week of owning it I took it to the dealer and they topped off the coolant. A week later the Insufficient Coolant message came on again and I topped it off with about 1 quart (litre) of distilled water. It's been ok for the last day or so. I haven't seen any external leaks. I love my Touareg, but I really hope this isn't the beginning of a bunch of problems.

Vehicle- 98 honda crv lx problem- it always starts when its cold (hasn't run for several hrs). Once its been running for a short while and is shut off, it either has a very hard time starting again or just won't start.
specifics- always starts the first time once engine is warm the problem starts engine turns but doesn't fire. Wears downs the battery. When I get it jumped the car will start sometimes the car will act sluggish during a left turn or from a dead stop when trying to accelerate quickly.
question- does this sound fuel pump related or battery related or both?
statement- car problems blow!

Our 1997 Lumina with a 3.1 liter engine and about 190,000KMS is having difficulty starting in the morning.
I have changed the spark plugs, plug wires, checked the connections to the battery and put dielectric grease on them. None of that seemed to make much of a difference. The key has to be held for about 5-7 seconds and it coughs to life and then runs rough for about another 5 seconds and the interior lights are dim during this too. After that it comes to life and runs great.
Is it possible for starters to start to weaken? I have never had a starter do that, they have either worked or not. Besides that, I don't know what else could be the problem.
I have heard that these engines can have condensation issues when the temperature straddles the freezing mark, which it has been the last few weeks. Maybe it just needs to get below zero and stay there?

Last summer and this summer I have had a hard time starting my car when it is hot and humid out. In the winter or on cooler days it starts right up, but on hot and humid days I have to crank on it for a while before it will fire up. Sometimes it will start up right away on these days but die immediately, then I am stuck sweating my butt off in a hot car while I crank on it to start.
What this might be? The Honda dealer was of no support, they tried to sell me a new starter and battery (it is turning so I know they are not the culprits.) When I finally got someone at the dealer to listen to me, he suggested a fuel relay, a sensor,r something else I can't recall. But in the end he said they would just be changing out all of these until one works, at my expense.

My moms 09 camry has a hard time starting and runs rough. I found out that when my father went to get an oil change, they put in 5W-30. The engine cap on the engine says 0W-20 or 5W-20. The car is at 70K and it has never had any issues, always ran smoothly, always started... until the last oil change. I have looked through the all the service logs and it seems that the last 3 services, they also used 5W-30 oil in the car.

So I have an 03' Camry le 4 cyl. And it has been having a hard time starting for a while. Finally it completely died. I tried to jump it but accidentally hooked up the jumper cable on the other car backwards. The car then wouldn't even try to start, found and replaced the alt fuse in the engine compartment (what a pita), so I jumped it correctly and it started, but would not move when shifted Into drive or reverse. When in gear pushing the gas pedal does nothing, no rpms at all.

I have a 1995 Toyota Previa that is having a hard time starting up consistently. Most of the time it starts like a charm, but about 15% of the time the vehicle won't start. It will crank away, sounding like it's out of gas, but just won't start up. BUT if I wait a couple hours and try again it will start up on the first time.
Mechanics have looked at it twice now and are stumped- and of course it starts up fine when it's at the shop. A new battery and a new relay device haven't worked.

I have a 2002 Nissan Altima that has a hard time starting but runs fine once started. It is very difficult in the winter when the temp is below 25 degrees. Sometimes it take me 5 to 6 tries to get it started. I have had the vehicle checked by two mechanics and recently had the battery replaced. The mechanics said the car looks fine. Could this be a fuel injector problem or moisture in the fuel system?

So I've had my car for 3 years now. I've done an emissions delete, replaced maf, diverter valve, coolant temp sensor, thermostat, timing belt kit, fuel filter, air filter, starter and battery (for another issue) have a 3" DP and replaced the O2 when I did that, valve cover gasket, spark plugs, tested another n75 in my car.
The problem: the car sometimes has a really hard time starting when it it way below freezing. When it's around cold, at freezing or under the car will start fine. But the problem starts after I back out of my driveway and take the clutch out and put on the gas. When I try to accelerate the car will not accelerate. You can have your foot pressed to the floor and the car will act as it's stalling out and sputter but it actually won't stall because the call will keep driving and then all of a sudden power will come back and it will take off. The situation can be remedied by either pushing the clutch in. The car will idle no mall or if when the car is sputtering I can tap the gas quickly an it will build up speed and the problem will go away.
