I believe that car has the intake plenum on top of the intake manifold. If you're having a leak, you can poke around the plenum (the big aluminum thing on top of your engine) with a piece of tubing as a stethoscope. You'll know then if you have an air leak. If you are somewhat savvy with a wrench, you may be able to make that repair yourself.
It sounds like your cam belt has slipped. If this is the 4-cam engine, you are supposed to replace the belt at a frequency outlined in your owner's manual. This is a much more advanced repair procedure. If this is the problem and you take it on and have a problem... post back here for help. Good luck.

What are the symptoms of a bad intake gasket on a 1999 buick century?


Coolant leaks,When the intake manifold gasket cracks or blows out, coolant will leak out of the intake manifold. You may see puddles underneath your car or notice smoke or steam coming off of the engine and exhaust from the coolant dripping onto it and then burning.Overheating, If the intake manifold gasket fails and allows coolant to leak out into the engine, your car will begin to overheat. If your car frequently runs low on coolant or begins to overheat, check the intake manifold gasket.Running poorly, When the intake manifold gasket falters, it affects the way the motor handles its emission gases. The change in pressure can affect the vacuum in the intake as well as how smoothly your car runs. Mainly, it will idle roughly and may hesitate, cough or sputter.

2004 Ford ranger rough idle at 1200 RPM. Hi, my ranger just came from the garage with no fix. It has 64000 miles and developed a sputter between 1000 and 2000RPM. Runs like hell and idle is fine , no...


Hello, I suspect the problem can be one of three things. An idle speed control Solenoid or a leak in the Intake system or bad valve runner operation. First, disconnect the accelerator cable at the Throttle connection. I am reading that you have a rough idle at 1200RPM and then that the idle is fine.

The idle is too high if it is set at 1200. By disconnecting the accelerator cable, you will find out if the cable is binding at low rpm. If the engine now idles slower with the cable off, you have found part of the problem.

The ISC, idle speed control, usually fits in a shallow well in the Intake, has a valve which routes extra air into the engine to smooth the idle. The valve shaft can be cleaned with WD40 and you can degum the passageway. Too much air at the wrong time can increase RPM and give the other controls fits trying to compensate, resulting in sputter.

A leaking intake manifold or manifold gasket can create the problems you describe. Use a hand spray bottle of water and mist the seams while the engine is running. A leak will draw in the water and change the RPM. Then fix the leak. Some 6 cylinder manifolds have 2 piece sandwich designs and the gaskets usually fail over time.

If you have the type of engine with intake runners, there are activating Pods which move rods underneath the Pods. Some have plastic clips which break and the rods fail to work after that.
Since the Electronics work, you will not get a check light. This defect sounds a lot like your problem because the Intake has certain flow designs to regulate power at different RPMs'. You are having problems only within a certain RPM range.

I hope my solution gives you new ideas on inspecting your engine for the problem.

1992 Lumina Backfire - I have a 1992 Lumina Euro, 77K miles, 3.1 V-6. Under moderate to hard acceleration the engine will backfire and you can smell gas. The spark control module, coils, wires, plugs,...


I know you mentioned the EGR valve has been replaced, but you may have a bad 'new' part. I know the car is electronic, but has anyone checked its ignition timing (timing belt been looked at, I know it only has 77k on it). Is the fuel pressure regulator OK and it vacumm supply?

Overheated , now a leak, dead battery, intake gasket, !!!


Could be the intake manifold gasket leak is upsetting the manifold vacumn which in turn will have an effect on the idling adjustments. The extra drag of the Auto Trans wnen engaged may cause the engine to 'cut-out'. Fix the manifold gasket first, re-adjust the idle, then see what you find.

Changed intake gaskets now car will start barely and idle really rough? rocker arms adjusted to 89 in lbs.


it sounds like you installed the wrong gaskets. this allows air to leak past the gasket causing a massive vacuume leak. It could also be the gasket is too small chocking off the air and causing the car to run rich.

Rough idle, Car shakes, sputters and misfires upon acceleration


It sounds like you may have a problem feeding the fuel to your engine, I had the same problem with my 89 RS. All the 1989 model's fuel systems were recalled. I think you may need a new fuel pump. The fuel pump is located inside the gas tank in the rear of the car right under the rear axle. The fuel pump itself isn't too expensive, but with other small parts such as the electrical harness upgrade and fuel filter and the labor you should be looking somewhere in the $500 range. I hope this helps.
