I have a 2001 SLK320. Throttle response when engine warm is non-existant until pedal half way down. If my problem is the Air Flow Sensor (MAF) is there any way to bench check the 5 terminals for continuity, shorts, opens, etc.?

If thats your only symptom and you have no error codes and no CEL I would not suspect the MAF. First thing is to check your transmission fluid and that there is no problem with transmission fluid wicking into the TCU. If they check out then reset the adaptive response of your transmission so it can relearn when to change gears by changing throttle response, its not difficult Turn the Key to the "on" position (the position right before you start your engine) Press and hold your gas pedal down for at least 5 seconds Turn Key to "off" position (dont remove the key) and then slowly release the gas pedal. than wait about 2 minutes or so, do not remove the key do not open the doors etc just sit there. afterwards, go drive your car the way you like to drive it and your transmission will readjust/relearn your style of driving (it stores the changes after the first 40 gear changes have been completed so pick a road that does a lot of changing) if you want to retrain the adaptive part of the transmission have a look at this link in benzworld http://www.benzworld.org/forums/w210-e-class/1387073-post-graduate-education-your-22-6x.html hope thats some help

Is there an O2 sensor on the pipe that the fuel module connects to? It should work perfectly as it does on my Yamaha Raider, and I have similar modifications.

Why do you mean Nuetral? If you mean no throttle but connected...put the left stick in the down position.

Check all connections, and press in on the remote wheel when accelerating. Maybe that would help.

Tighten the idle screw or loosen with engine runing I believe tightening it with gain you more torqe but losening it will get you top end speed . So if you tighten you will have better throttle responce in launch but it will decrease how fast you want to go . Loosen less power at. Start 1-10mph but witl pick up and haul @$$

Please explain what you mean by neutral? As far as I know the throttle is either on or off.

Press the throttle stick to off then full throttle and back which initializes the motor controller. Its like a safety so you can connect with partial throttle.

Although not critical, most manufacturers highly recommend disconnecting the battery before removing/connecting MAF sensors. Failure to do so may introduce a spurious voltage spike into this sensitive device, thus maybe damaging/destroying it.

It's one of the actuators, there are two. If you replaced the control panel listed here already then this is the problem. If driver is blowing cold then you likely replaced the wrong actuator. http://www.sparkys-answers.com/2009/09/2004-chevrolet-tahoe-blows-hot-air.html?m=1

I sincerely don't have the answer, sorry. But if you google this "2004 Lancer 1.6 GLX motor" and see the images, you can see that some people uses an extension instead of the MAF sensor. (Didn't even knew you could NOT have the MAF)

Does it stop spinning if you lower the throttle to zero? If it doesn't then the controller is defective. Suggest returning the complete unit it to exchange for a new set. Best wishes.

Interesting thing...I experienced this issue yesterday as well. The wire which opens throttle for auger and connected to the bar which engages it gets a bit loose. Try to pull it with your hand, you will see the difference. That being said, there is a metal plate with holes under the rubber cover on that wire where you can adjust tension of the wire connected to the throttle. Please note it is not easy to do, sometimes, if no one helps you. But it is doable. Let me know if you have further questions.

There are two fuel adjustments, one for low speed (idle) and one for high speed, Don't touch them. The carb is ready to go as it is. The only air flow adjustment is the choke control for starting. Once the unit is warmed up the choke should be wide open for normal operation. Just make sure you replace the gasket between the engine and the carb.

Hi Graziela, I had this problem as well I took the car to the dealership and after troubleshooting it turned out to be an error from the mass airflow sensor. They told me it was no big deal and they reset the error codes for me. If your car is still under warranty I suggest taking it to the dealership so they can fix that for you, if not, you can take your car to an AutoZone and they can clear those codes for you for free.

Hi John. I bought this hoping that I wouldn't have to replace the whole throttle body as you are probably trying to do. As I recall, the position of the slot relative to the body cannot be changed, it is spring loaded. I had hoped to install it, adjust the position by turning the body, and then securing it with the screws when I got the position right based on the idle, but I could not get it to work. The idle was too high and I could not bring it down. The local shop couldn't adjust it either, apparently they are calibrated together at the factory. I ended up having to buy a whole new throttle body assembly. Hi John. I bought this hoping that I wouldn't have to replace the whole throttle body as you are probably trying to do.

Make sure you follow the instructions regarding the throttle. If it is in the wrong position it will shut off.

Very cool. Thanks. Im hoping its the temp sensor as I already replaced the element so far and thats the only thing left. Thanks again
