Chevrolet - 1500 :: 1989 Truck Will Start But Not Run For More Than 30 Seconds

My truck hasn't run for over a year and no one seems to be able to tell me why. The fuel pump supposedly has 10 lbs of pressure, it has new fuel pump relay, new throttle body, and probably more new things (can't remember exactly). It will start up normally and then it will act like it's not getting fuel and within seconds die. If I keep my foot on the gas and kind of pump it (I know it's EFI) it will try to keep running, but will die, and it really gets rough toward the end like the whole engine's going to fall out. The truck has 300K+ on it but the engine was replaced about 10,000 miles ago. It still has a lot of original equipment.

Ford Fuel System :: Fast Idle Speed Holds The Throttle At 1500 RPM On Cold Start

Carburetor: Autolite 4100
Fast Idle Speed: 1250 RPM
Curb Idle Speed: 600 RPM (At normal operating temperature)

When I cold start my truck, the fast idle speed holds the throttle at 1500 RPM. I will let it idle about 30 seconds or so, and then I will tap the gas to bring the idle down.

When I do this, the idle will immediately drop all the way down, and too low for a cold engine. The engine won't stall, but it will hover just below 500 RPM, which is a bit too low to idle smoothly.

But when the engine is at operating temperature, the idle speed is 600 RPM and the engine will happily idle smoothly.

Shouldn't there be an "in between" speed? When I tap the gas pedal at 1500 RPM to bring the idle down some, shouldn't the speed drop down a little lower, like 1000 RPM since the engine is still a bit cold?

If so, what do I need to adjust? The Autolite 4100 works PERFECTLY otherwise.

Cavalier - Chevrolet :: 2002 - Surges Forward While Idle & Rev Up To 1500 Rpm?

I am having issues with my 2002 chevy cavalier.

The car occasionally surges forward while idle and revs up to 1500 rpm approximately occasionally when the air conditioner is on... if the brake is not applied I move forward.. the lurches are continuous every 3 seconds or so.

I am getting a code for an evap leak.. I have replaced the purge solenoid valve, gas cap, and checked all connections with no luck... slightly decreased gas mileage has occurred.

A little bit of a slick substance has been leaking from the car.. it has the consistency of water, but leaves a slight brown tinge on concrete.

Chevrolet - 1500 :: 1997 - Won't Start / Idle Rough?

I have a 97 Chevy K1500 truck that i have been having problem with starting. Sometimes it will start. When it does the idle is rough. When i put in in gear it almost acts like it will shut off. Then it comes back and it drives fine. If it shut it off it may or may not start. I had the distributor cap a rotor replaced. Then I replaced the spark plugs and wires. Still does not start. It seems like it is getting too much fuel. I pulled the fuel pump relay and the truck would start then die out. When i put the relay back in truck does not start. I am not sure what might be the next piece to look at. I was thinking the MAP sensor or the throttle position sensor. So far i have not had any codes come up.

Chevrolet - 1500 :: 1991 Truck Died For 2 - 3 Seconds Only To Refire Itself

1991 chevy silverado 1500 4.3 ... Cruising at 55 down highway truck died for 2-3 seconds only to refire itself. After doing so for a few days it wouldn't start at all. Changed fuel pump,fuel filter and all spark plugs. Now runs fine until I shut it off briefly. Then it stalls on me on 3rd,4th and 5th gears. Bucks badly. Is it a fuel issue or something to do with starting it while it's warm. Also it runs good with the check light ON. Soon as it goes off it starts shutting off and refiring itself when I give it gas.

Accent LC (2000-05) :: 2003 - Idle Varies Between 800 To 1500 Intermittently Within Seconds

My car is standard 5 speed transmission, when my car is running my idle varys between 800ish to 1500 intermittently within seconds and if I don't drive it after starting the car it will stall on me (in neutral) after the rpms go up and down about 9 times.

The thing I found is if I disconnect my idle air control valve attached to my throttle body it stops the jumps in rpm. I have tried replacing the valve with one of my friends control valve Hyundai accent 2004 that works and fits perfectly on his doesn't work on mine. Right now I have my idle air control valve disconnected at the moment but i want to fix this issue because my rpms are at 1300 at idle.

Chevrolet - 1500 :: 2004 - No Pressure At Idle Just Below 40 When Driving

2004 1500 5.3 low oil pressure after using Lucas engine stop leak. No pressure at idle just below 40 when driving. Replace the sending unit and pressure improved for about a day. Just had a manual pressure gauge hooked up and it shows the same as cluster. No engine noise at all. I was informed that using Seafoam or another solvent could loosen up build up and cause damage. Trying to find out if using an engine flush machine may support. I am assuming that the cause of the low oil pressure is due to build up from using several qt of the stop leak over a four months. I am the only owner and I have always changed the oil according to schedule and have always used Valvoline synthetic.

Chevrolet - 1500 :: 2009 - Noticed Irregular Fluctuation In Idle

I just bought a 2009 Chevy Silverado , have only had for a week and have noticed an irregular fluctuation in idle, also the transmission has lack of a better term jarred a few times and seems to downshift rough sometimes. The irregular idle seems to be worse when the ac is on, I can hear the compressor kick on and off alot. And just once I was driving and tried to accelerate and it didn't want to very much. Factory warranty is out and dealer didn't give option for extended warranty. They have agreed to look at it but aren't willing to do much other than clean injectors and throttle body.

I tried all the ways to do it like on YouTube. What is wrong with my truck?

Chevrolet - 1500 :: Loud Whining / Spinning Noise On Startup - High Idle

My question is what could cause a high idle?I have a 95 Chevy pickup 4x4 with a 5.7... Recently the lower radiator hose fell came off the radiator, dumping the liquids all over the street. The motor shut down, and every time we went to start it there would be a loud whining/spinning noise. We thought that the motor seized, so we pulled the plugs, turned the motor by the crank bolt.Turned out that the starter went bad, the spindle and bendex werent catching on the flywheel.

After examining the flywheel teeth, and gapping the plugs to the recommended manufacture gap, (they werent when we pulled them), we got a new starter installed. It started right up! But it ran at a high idle, around 1500-2000 RPM. I did not have a chance to really let it warm up (it was cold and raining). Now there is a gray flexhose that is running from the air filter housing down to the exhaust manifold. If i remember correctly, it was not seated very well when I took it off. Could it be causing too much of a vacuum?

Passat (B6) :: Cold Start Idling / RPMs Would Stay At 1500 For A Quick 20 Seconds

In the first two years of ownership of my Passat, when I would turn the car on during cold days, the rpms would stay at 1500 for a quick 20 seconds until the car got a bit warm and then would drop down to about 800. Recently, when I turn the car on cold days, the rpms drop directly to 900 and below.

The problem: Steerage issue. No problem exhibited while driving. However, at stop or very slow there is a loss of power steering but only when turning the wheels right. There is also an audible sound when turning to the right. Kind of a whooshing or air expulsion?
