I have a 2000 Lincoln Towncar. 50k mi. Erratic idle, surges, occasionally stalls when idling and foot on brake, only when engine is cold... 4.6L. Runs fine when engine is warmed up. It also has air suspension. Cold where I live is 40F...so it only acts this way in the winter months...OK in the spring, summer, and fall. I have not taken the car to a mechanic.

1994 jimmy 4.3 vortec. revs and idles perfect in park. start driving down road and engine surges almost cuts out. even tried putting under load with foot on brake gave it gas, no misses till driving down road

This sounds like a dirty fuel filter to me hence the load has no effect till driving as the fuel supply will be proportional to the revolutions of the engine whether it's fuel injection or not.When you are driving you are obviously using more fuel so ... Cars & Trucks

1985 mercury grand marquis. Starts then stall, usually more then once. Once started motor surges and then may stall again when put in reverse. Motor surge continues as you begin to accelerate and proceed down the road. When stepping on the accelerator, no response for a few seconds, lift foot and press again, might respond. When stopped with foot on brake, motor continues to serge and must keep foot on accelerator and brake at the same time to keep running. Then sometimes, it runs like a t

My 2001 Saturn SL1, when in gear idles (when I have my foot on the brakes) at 1300-1500 RPM. When I put it in park it idles at 2500 RPM. Tonight I noticed that from a complete stop at a stop sign, I can let my foot off the brakes and it will go and gain speed up to about 35 MPH without me stepping on the accelerator. Is this a throttle issue or something else?

Erractic abnormal high idle.. When first started the idle runs high 2200 plus rpms did not kick down to normal sometimes for quite a while..

98 dodge ram 3500 4x4 5.9l cummins diesel vin dthis truck will start everytime. Will idle all day long in park or neutral. It stumbles and dies when put in drive or reverse.

I own a 1998 Ford F150 V8, 4.6L engine with approx. 273,000 miles. My truck has a high idle problem. Whenever I am driving for awhile and come to a stop, the engine idles well pass 1500 RPMs. In fact, the idle is so high, it requires me to keep my foot on the brakes to prevent running into the car in front of me. Once it starts idling high, it continues until I turn the truck off. Can you advise on what is causing the truck to idle at very high RPMs after being driven?

When stopped at anytime in gear or neutral on a 99 Astro it idles normal, but when you start to move the idle jumps up like you are double foot driving. If you are moving and put it in neutral it will drop to normal idle, or you stop at a red light it is high until you come to a complete stop then it returns to idle. It is like you are power braking until you stop exp.

My 2006 Kia Sorento Ex 3.5L V6 idles at 1000 and when driving when I remove my foot the idle doesn't go down quick. What is supposed to be the engine idle speed for this model as the car seems to keep pushing and we have the apply the brakes harder to slow it down. The dealership says the high idle is ok and won't do anything about it. We asked another friend that works at a Kia far from us and he says 750.

Kia Optima I just replaved my timing belt, oil pump belt, crank senser, map senser, R & R senser. The timing belt was not broke but did have a few missing teeth. It will start and run just fine on a cold motor. After the motor warms up it has a rough idle, low idle, and will eventually die without keeping the idle up with my foot on the gas pedal. It will surge on highway speeds, most climbing hills. It also has developed a vibration while accelerating. Jump before it shifts into a higher gear.

Is the car flashing any codes. I would look for fuel issues possibly fuel filter, injectors etc. Because these items are easier to check. Otherwise it sounds as if the timing is off on the car. If the Hydraulic tensioner is not replaced this coul ... 2004 Kia Optima

My 2000 Chevy Impala 3.4 shuts down when I take my foot off of the gas peddle completely. At a light I must have a foot on the brake while the other foot is on the gas and I must give it gas to start it. I.v changed the master air flow, The Idle control sensor, the throttle position sensor and the pcv valve connections. What else could the problem be? (oh yeah, there is no check engine light with all of this)

Surging I have a 2001 Crown Vic that surges only when the AC is on. It idles higher then it should whe the AC kicks in. It will also surge when I take my foot off the gas when driving on the highway. It only happens when the AC kicks in. What gives? Any ideas? Thanks

Surge Problem Robotek, The surge is pretty substantial. The RPM's go up top the point where the car wants to lurch ahead even with your foot on the brake. Coming into the garage I need to be very careful with it as it will go into the wall if I am not really anticipating the surge. Any ideas?

You could try disconnecting the air valve and see what happens.The car may stall when idling if you turn on the air, just set it to idle high and leave the air on all the time :)Keep me updated manregardsrobotek ... 2001 Ford Crown Victoria

2000 chevy s10 runs for a few minutes then dies. Had fuel pump, fuel pump relay and fuel filter replaced at shop but the thing will still not run properly. You have to keep your foot on gas to keep it from dying so the idle has to be above 1500 rpms to stay running. If you let foot off gas it dies. So you have to keep foot on gas pedal and one on brake to drive it. Someone help me I am about to run the thing off a bridge

Hi Allen, The brake booster is connected to the intake manifold and that is where the low pressure is generated. If the diaphragm or one way valve, or connection pipe is leaking it will give the same effect as a leakage on the intake manifold. The sy ... GMC Sierra
