When engines are cold, it is usually normal for them to run a little bit rough due to the EGR valve and the timing of the engine with the manifold and components being cold. It takes time to vaporize the fuel to achieve full combustion. The automatic throttle should activate and put the engine at an RPM approximately 1500 to 1800. At this RPM, you should not run the car otherwise you risk losing your transmission in the long run. It may be also wise to tune up your car by checking the spark plugs, the contact points and the timing mechanism. An erratic timing mechanism can give you a rough idle.

Sounds like a faulty mass air flow sensor.Try spraying the small thin wires with a nono-chlronated brake cleaner then let it dry for 10-15 minutes then re-install.Make sure to reset the computer whether you clean it or replace it with a new one.

I have a 2000 gmc sonoma with a 2.2l. truck shifts through all gears fine but in overdrive running at 55 or 60 the rpm will jump between 1800 and 2500 but runs most of the time at 2500. If i work the gas...


Sounds like TPS (Throttle Positioning Switch) They develop "hot spots" or wear spots usually at throttle positions that are commonly used alot IE: cruising speed. When they get hot spots they fluctuate looking for solid connection. Replace TPS.

It's been almost 2 years since you posted the question so it's likely you will not see my answer to your question.

First, do NOT make any adjustments to your throttle body idle setting. The screw most likely never budged since 2006 so you should not touch it since this is not the root cause. But yes it is wise to check all vacuum lines as "craig" suggested.

I have a 2007 Corolla CE, 1.8 liter VVT engine, 5 speed manual transmission which I bought new from the dealer. Currently has about 108k miles on it. After about 4 or 5 years in cool to cold weather it started doing the same thing. I researched it online then asked my local Advance Auto Parts person who confirmed my hunch. It is known as "idle hunting" when the engine is cold, in colder outside temperatures the idle rpm's will increase up to roughly 2000 rpm then drop to idle, then back to 2000 rpm, then repeats multiple times. Then after driving a short distance, stopping and running at idle, the idle speed may drop to 600 or 500 or as low as 400 rpm, running quite roughly but still keeps running. My Corolla normally idles smoothly and steadily at 800 rpm when warm or hot. The idle hunting or low idle rpm will typically correct itself when the engine warms up enough.

The problem: the intake manifold gasket has aged and shrunk a bit, allowing engine compartment air to get pulled directly past the gasket and into the cylinder head intake port. This causes an imbalance between the reduced air filter airflow sensed by the Mass AirFlow (MAF) sensor versus the actual air/fuel ratio versus the engine rpm versus the oxygen level in the exhaust stream. The gasket will shrink more as the temperature under the hood drops, allowing more air to flow past the gasket. The Engine Control Unit (ECU) is simply trying to do its job as programmed by increasing fuel delivery to compensate for the overall imbalance, then when rpm's get too high it will reduce fuel delivery.

The solution: purchase a new intake manifold gasket for roughly $10 to replace the stock gasket. Mine is a thin orange polymer gasket with round cross-section which seals around all 4 intake ports. You can search for instructional video of how to install it on YouTube.

I purchased one but did not install it yet. I am sure this will resolve the problem since all other suggested fixes I found on the internet did nothing but unnecessarily frustrate the owners.

Cruise control went out on my 2005 ford taurus and my accelerator gets stuck at times. Should I replace the cruise control?


This is a dangerous defect. What you want to do is isolate the Cruise cable from the Throttle mechanism. Then get the Cruise cable away from the Throttle so it can not jam the Throttle accidentally.

With the engine OFF use your hand and move the remaining Throttle mechanism and feel for sticking or roughness in the control. If you feel binding, start removing the connection of the Throttle cable and work your way through all the moving parts like a Butterfly flap on the Airhorn, the TPS (throttle position sensor) and so on until you find out what is rubbing.

It is possible that the Cruise was disengaging because the Throttle parts were binding. If disconnecting the Cruise eliminates the sticking throttle, then all the problems came from the Cruise control cable or the Cruise Box. Once you have made a thorough check of the Throttle you can blame the Cruise for your problems and replace the parts.

Check idle air control valve. If functioning properly and next common problem from my experience is a BAD CRANK SENSOR. Good Luck and thanks for using FIX YA
